◆ restoreDefault()

Component restoreDefault ( )

inlineinherited

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 mv.impact.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 ( int index )

inlineinherited

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 mv.impact.acquire.Component objects are selected by the current one call mv.impact.acquire.Component.selectedFeatureCount. This value minus 1 will also be the max. value for index.

See also: mv.impact.acquire.Component.selectedFeatureCount,
mv.impact.acquire.Component.selectedFeatures

Since: 1.11.20

Returns: A mv.impact.acquire.Component that is selected by the current one.

Parameters

[in] index The index for the component to query.

◆ selectingFeature()

inlineinherited

Retrieves a component that is selecting the current one.

This function retrieves a component that is selecting 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.

Property Documentation

◆ changedCounter

uint changedCounter

getinherited

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 mv.impact.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.

Example

//-----------------------------------------------------------------------------
public struct ComponentRef
//-----------------------------------------------------------------------------
{
  mv.impact.acquire.Component m_pc;
  uint m_lastChangedCount;
  public ComponentRef( mv.impact.acquire.Component* pc ) : m_pc(pc), m_lastChangedCount(0) {}
};
 
//-----------------------------------------------------------------------------
public void fn( ComponentRef cr )
//-----------------------------------------------------------------------------
{
  if( cr.m_pc )
  {
    uint currentChangedCount = cr.m_pc.changedCounter;
    if( currentChangedCount != cr.m_lastChangedCount ) )
    {
      // something has happened since the last check.
      doWhatNeedsToBeDone();
      // and remember the current changed counter
      cr.m_lastChangedCount = currentChangedCount;
    }
  }
}

Returns: The current changed counter of this object.

◆ changedCounterAttr

uint changedCounterAttr

getinherited

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 mv.impact.acquire.ComponentAccess.changedCounter (except in case of a wrap around) when called at the same time for the same object.

See also: mv.impact.acquire.ComponentAccess.changedCounter

Returns: The current attributes changed counter of this object.

◆ componentEnumerable

get

Returns an enumerator that iterates through the collection.

This interface will allow to e.g. write code like this:

ComponentList cl = new ComponentList(getHandleFromSomewhere());
foreach (Component c in cl.componentEnumerable)
{
  Console.WriteLine("{0}", c.name);
}

See the frameworks documentation about the System.Collections.IEnumerable interface for more information.

Returns: An enumerator that iterates through the collection

◆ componentListEnumerable

IEnumerable<ComponentList> componentListEnumerable

get

Returns an enumerator that iterates through all the mv.impact.acquire.ComponentList elements in the collection.

This interface will allow to e.g. write code like this:

ComponentList cl = new ComponentList(getHandleFromSomewhere());
foreach (ComponentList cl in cl.componentListEnumerable)
{
  Console.WriteLine("{0}", cl.name);
}

See the frameworks documentation about the System.Collections.IEnumerable interface for more information.

Returns: An enumerator that iterates through the collection

◆ componentTree

String componentTree

get

Returns a string representation of the full component tree residing in the current list.

◆ contentDescriptor

String contentDescriptor

get

Returns a string containing information about what's in this list.

This string might not be defined by every list but in any case this function will return a valid string. However this string might be empty.

◆ displayName

String displayName

getinherited

Returns the display name of the component referenced by this object.

Returns: The display name of the component referenced by this object. This might be an empty string if no display name has been specified.

◆ docString

String docString

getinherited

Returns a string containing general information about the component referenced by this object.

Returns: A string containing general information about the component referenced by this object.

◆ firstChild

Component firstChild

getinherited

Moves to the first child of this component(moves down one level).

Calling this function will only succeed, if the current mv.impact.acquire.Component references a list.

Returns: A new mv.impact.acquire.Component object

Examples: Properties.cs.

◆ firstSibling

Component firstSibling

getinherited

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

Returns: A new mv.impact.acquire.Component object

◆ flags

TComponentFlag flags

getinherited

Returns the flags associated with this component.

Returns: The flags associated with this component.

◆ hObj

int hObj

getinherited

Returns a unique identifier for the component referenced by this object.

Returns: A unique identifier for the component referenced by this object.

Examples: GenICamCallbackOnEvent.cs, and Properties.cs.

◆ isDefault

bool isDefault

getinherited

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

bool isList

getinherited

Checks if this component is of type mv.impact.acquire.ComponentList.

Returns

true if the component references a list
false otherwise

Examples: Properties.cs.

◆ isMeth

bool isMeth

getinherited

Checks if this component is of type mv.impact.acquire.Method.

Returns

true if the component references a method
false otherwise

◆ isProp

bool isProp

getinherited

Checks if this component is of type mv.impact.acquire.Property or a derived type.

Returns

true if the component references a property
false otherwise

Examples: GenICamCallbackOnEvent.cs, and Properties.cs.

◆ isValid

bool isValid

getinherited

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 mv.impact.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.

Examples: GenICamCommonSettingsUsage.cs, and Properties.cs.

◆ isVisible

bool isVisible

getinherited

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 mv.impact.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 mv.impact.acquire.Component when it's not visible however the actual data will be used only if the Component is visible (mv.impact.acquire.TComponentFlag.cfInvisible must NOT be set).

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

◆ isWriteable

bool isWriteable

getinherited

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.

Examples: Properties.cs.
