A base class to implement access to internal driver components.
Objects of this class can be constructed directly even if nothing is known about the type of driver object we are referring to. This class acts as a base class to provide access to internal properties, methods and component lists offered by the driver.
This object can be used to navigate through component lists of unknown content.
Consider the following structure:
Where the prefix 'L' means this is a list, 'P' that this is a property. Assuming that we have and iterator referencing list 'C', calling mvIMPACT.acquire.Component.firstChild e.g. would return a new iterator referencing object 'PE', while calling mvIMPACT.acquire.Component.nextSibling would have returned a reference to 'PD' and mvIMPACT.acquire.Component.parent would have returned a reference to object 'LA'.
"EXAMPLE 1":
A new mvIMPACT.acquire.Component is created with the ID of list 'C':
"EXAMPLE 2":
Iterate over a complete list including sub lists. This will result in a list of all lists and properties that reside in the list the iterator currently is moving through to be written to the standard output. The name of the component and every parent component will be printed into the standard output:
| __init__ | ( | self, | |
| * | args ) |
Constructs a new access object to a driver object.
OVERLOAD 1:
| hObj | [in] A valid handle to a component object |
OVERLOAD 2: Constructs a new unbound access object.
OVERLOAD 3: Constructs a new mvIMPACT.acquire.Component from an existing one.
| src | [in] A constant reference to the mvIMPACT.acquire.Component object, this object shall be created from |

| docString | ( | self | ) |
Returns a string containing general information about the component referenced by this object.
| firstChild | ( | self | ) |
Moves to the first child of this component(moves down one level).
Calling this function will only succeed, if the current mvIMPACT.acquire.Component references a list.
| firstSibling | ( | self | ) |
Moves to the first sibling(the first feature in the current list of features).
| flags | ( | self | ) |
Returns the flags associated with this component.
| flagsAsString | ( | self, | |
| * | args ) |
Returns the flags associated with this component as a string.
| separator | [in] A user definable string to separate the individual flags. The default value is ' | ' resulting in the string to look e.g. like this: 'cfWriteAccess | cfReadAccess' |
| getIsDefault | ( | self | ) |
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.
| getIsList | ( | self | ) |
Checks if this component is of type mvIMPACT.acquire.ComponentList.
| getIsMeth | ( | self | ) |
Checks if this component is of type mvIMPACT.acquire.Method.
| getIsProp | ( | self | ) |
Checks if this component is of type mvIMPACT.acquire.Property or a derived type.
| getIsValid | ( | self | ) |
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.
| getIsVisible | ( | self | ) |
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.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.
| getIsWriteable | ( | self | ) |
Checks if the caller has write/modify access to the component.
|
static |
Returns the recommended representation converted to a string.
| representation | [in] The representation to query the string representation for |
|
static |
Returns the type of the component referenced by hObj.
| hObj | [in] The component the type shall be retrieved for |
|

| visibility | [in] The visibility to query the string representation for |
| lastSibling | ( | self | ) |
Moves to the last sibling(the last feature in the current list of features).
| nextSibling | ( | self | ) |
Moves to the next sibling(the next feature in the current list of features).
| parent | ( | self | ) |
Moves to the parent of this component(moves up one level).
| representation | ( | self | ) |
Returns the recommended representation for this component.
The representation can be used e.g. to develop a GUI that creates convenient controls for certain features.
Valid values for this property may be: mvIMPACT.acquire.crUndefined, mvIMPACT.acquire.crLinear, mvIMPACT.acquire.crLogarithmic, mvIMPACT.acquire.crBoolean, mvIMPACT.acquire.crPureNumber, mvIMPACT.acquire.crHexNumber, mvIMPACT.acquire.crIPv4Address, mvIMPACT.acquire.crMACAddress, mvIMPACT.acquire.crFileName, mvIMPACT.acquire.crDirectoryName.
| representationAsString | ( | self | ) |
Returns the recommended representation of the referenced component as a string.
| restoreDefault | ( | self | ) |
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.
| selectedFeature | ( | self, | |
| index ) |
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.
| index | [in] The index for the component to query. |
| selectedFeatureCount | ( | self | ) |
Returns the number of features selected by the current one.
| selectedFeatures | ( | self, | |
| v ) |
Retrieves the list of components that are selected by the current one.
