Member Function Documentation

allowsValueCombinations()

boolean allowsValueCombinations ( )

inherited

Checks if this enumerated property allows the combination of enum values.

If this function returns true, the enum constants can be 'ored' together. This works for the enum constants as well as for the string representations returned in the properties translation dictionary.

if a property e.g. defines a dictionary (('1', "one"), ('2', "two")) the following write operations will be valid:

prop = getPropFromSomewhere()
prop.write( 1 | 2 )
prop.write( "one | two" )

If this function returns true code like this will be valid:

ImageProcessing ip = new ImageProcessing( pDev );
ip.getMirrorMode().write( TMirrorMode.mmTopDown | TMirrorMode.mmLeftRight );

Returns

• true if this property allows the combination of enum values.
• false otherwise.

changedCounter()

long changedCounter ( )

inherited

Returns the current changed counter for the component referenced by this object.

This changed counter is incremented internally each time the component is modified. To check if this component has been modified since the last time, this check has been performed, keep track of the last return value of this function and compare it with the new value. This can be helpful e.g. to keep a GUI up to date. The value returned by this function will always be larger than or equal to the value returned by mvIMPACT.acquire.ComponentAccess.changedCounterAttr (except in case of a wrap around) when called at the same time for the same object as it's always incremented when the component has been modified in any way while the latter one will only be incremented if the attributes (e.g. the flags) but NOT if e.g. the value(s) of a property has been modified.

import mvIMPACT.acquire.*;
 
//-----------------------------------------------------------------------------
public class ComponentRef
//-----------------------------------------------------------------------------
{
  private Component c_;
  private long lastChangedCount_;
  public ComponentRef( Component c ) : c_( c ), lastChangedCount_( 0 ) {}
  public Component getComponent()
  {
    return c_;
  }
  public long getLastChangedCounter()
  {
    return lastChangedCount_;
  }
  public void setLastChangedCounter( long changedCounter )
  {
    lastChangedCount_ = lastChangedCount;
  }
}
 
// ...more code, class definition etc.
 
//-----------------------------------------------------------------------------
public static void fn( ComponentRef cr )
//-----------------------------------------------------------------------------
{
  if( cr.c_.isValid() )
  {
    final long currentChangedCount = cr.getComponent().changedCounter();
    if( currentChangedCount != cr.getLastChangedCounter() )
    {
      // something has happened since the last check!
      doWhatNeedsToBeDone();
      // and remember the current changed counter
      cr.setLastChangedCounter( currentChangedCount );
    }
  }
}

Returns

The current changed counter of this object.

changedCounterAttr()

long changedCounterAttr ( )

inherited

Returns the current attribute changed counter for the component referenced by this object.

This changed counter is incremented internally each time the components attributes have been modified. To check if this components attributes have been modified since the last time, this check has been performed, keep track of the last return value of this function and compare it with the new value. This can be helpful e.g. to keep a GUI up to date.

Note

Attributes changes are e.g. a modification to a property's translation dictionary, but NOT a property's value. Because of this the value returned by this function will always be less or equal than the value returned by the function mvIMPACT.acquire.ComponentAccess.changedCounter (except in case of a wrap around) when called at the same time for the same object.

Returns

The current attributes changed counter of this object.

inherited

Returns whether this property defines a translation dictionary or not.

Returns

• true if this property defines a translation table
• false otherwise

Since

1.12.63

Returns

• true if this property defines a minimum value
• false otherwise

hasStepWidth()

boolean hasStepWidth ( )

inherited

Returns

A unique identifier for the component referenced by this object.

isDefault()

boolean isDefault ( )

inherited

Checks if this component is currently referencing the default for this component.

This function will return true only for derived components that have not been modified.

Returns

• true if the component is currently set to its default value
• false otherwise.

isList()

boolean isList ( )

inherited

Checks if this component is of type mvIMPACT.acquire.ComponentList.

Returns

• true if the component references a list
• false otherwise

isMeth()

boolean isMeth ( )

inherited

Returns

• true if the component references a property
• false otherwise

isValid()

boolean isValid ( )

inherited

Checks if the internal component referenced by this object is still valid.

This function can be used to verify whether a referenced component is still valid or not. When e.g. referencing a driver property after mvIMPACT.acquire.Device.close has been called this function would return false. Calling any other function that tries to access the referenced component in that case would raise an exception.

Returns

• true if this object currently references a valid component
• false otherwise.

isVisible()

boolean isVisible ( )

inherited

Checks if the component is currently shadowed due to a settings made elsewhere or not.

Settings applied to certain components might affect the behaviour of others. For example an activated automatic gain control might shadow the value written to the gain property by the user as the gain is calculated internally. In order to check if modifying the actual component will affect the behaviour of the system this function may be used. When it returns true, the mvIMPACT.acquire.Component will have an impact on the system, if false is returned, the feature might be modified, but this will currently NOT influence the acquisition process or the overall behaviour of the device or driver.

This is what is called visibility. The user still might modify or read the current mvIMPACT.acquire.Component when it's not visible however the actual data will be used only if the Component is visible (mvIMPACT.acquire.TComponentFlag.cfInvisible must NOT be set).

The visibility of a mvIMPACT.acquire.Component object will change only if other mvIMPACT.acquire.Component objects are modified and NEVER when a program runs but does not change any mvIMPACT.acquire.Component.

isWriteable()

boolean isWriteable ( )

inherited

Checks if the caller has write/modify access to the component.

Returns

• true if the caller is allowed to call write/modify operation for this component.
• false otherwise.

lastSibling()

Component lastSibling ( )

inherited

Moves to the last sibling(the last feature in the current list of features).

Since

1.10.64

A new mvIMPACT.acquire.Component object

maxValCount()

long maxValCount ( )

inherited

For the majority of properties this function will return '1', but as properties might manage more than a single value, this value might be interesting from time to time.

Returns

the maximum number of values that can be managed by this property.

name()

String name ( )

inherited

Returns the name of the component referenced by this object.

Returns

The name of the component referenced by this object.

resizeValArray()

Property resizeValArray ( long newSize )

inherited

Resizes the property's data array.

This function resizes the internal data array of this property. The size of this array represents the number of values, which can be stored within the property. This function will only succeed, if the mvIMPACT.acquire.TComponentFlag.cfFixedSize is NOT set for this property and the user has "write rights" for this property. Otherwise an exception will be thrown. Whenever the user successfully writes an array of values to a property and this array contains more elements than the current internal data array can accommodate at the desired offset the internal data array will be increased automatically.

Note

If the caller does not have the needed rights this function might throw an exception of the type mvIMPACT.acquire.ImpactAcquireException.

In order to be allowed to modify the number of values a property can store, the mvIMPACT.acquire.TComponentFlag.cfFixedSize flag must NOT be set.

See also

mvIMPACT.acquire.Component.isWriteable

Returns

A const reference to the calling property.

Parameters

newSize

[in] The new number of values this property shall be allowed to store

restoreDefault()

Component restoreDefault ( )

inherited

Restores the default for the referenced component.

Calling this function will restore the default value for the component referenced by this object.

If this function is called for an object of type mvIMPACT.acquire.ComponentList every component in that list is restored to the default value.

Note

The caller must have the right to modify the component. Otherwise an exception will be thrown.

Returns

A const reference to the component.

selectedFeature()

Component selectedFeature ( long index )

inherited

Retrieves a component that is selected by the current one.

This function retrieves a component that is selected by the current one. This information is mainly useful for GUI applications that want to arrange features in a way that dependencies between features can easily been spotted.

When a component 'selects' other components, this indicates that selected components may change whenever the selecting component changes. An example for a selector might be a property defining the index within a LUT while the value of a particular LUT entry could be a selected feature. Assuming 2 properties LUTIndex and LUTValue then changing LUTIndex will invalidate and possibly change LUTValue.

To find out how many mvIMPACT.acquire.Component objects are selected by the current one call mvIMPACT.acquire.Component.selectedFeatureCount. This value minus 1 will also be the max. value for index.

writeS() [3/4]

Property writeS ( StringVector sequence )

inherited

Assigns new values to this property.

The user must have "write rights" for this property in order to be able to modify its values. Also if index is greater than the current internal data array size of this property the user must be allowed to change to size of the properties internal data array (the mvIMPACT.acquire.TComponentFlag.cfFixedSize flag must NOT be set). This function behaves exactly like mvIMPACT.acquire.Property.writeS except that is can be used to assign more than one value at the same time. The parameter index here serves as an offset. If for example a property holds 3 values 'one', 'two' and 'three' before this call and the function is then called with an array containing the string 'orange' and 'blue' and index = 2 then after a successful call to this function the property will hold the data 'one', 'two', 'orange' and 'blue'.
