Detailed Description

Store zero or more vtkInformation instances.

vtkInformationVector stores a vector of zero or more vtkInformation objects corresponding to the input or output information for a vtkAlgorithm. An instance of this class is passed to vtkAlgorithm::ProcessRequest calls.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

◆ PrintSelf()

void vtkInformationVector::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObjectBase.

◆ GetNumberOfInformationObjects()

int vtkInformationVector::GetNumberOfInformationObjects ( )
inline

Get/Set the number of information objects in the vector.

Setting the number to larger than the current number will create empty vtkInformation instances. Setting the number to smaller than the current number will remove entries from higher indices.

Definition at line 49 of file vtkInformationVector.h.

◆ SetNumberOfInformationObjects()

void vtkInformationVector::SetNumberOfInformationObjects ( int  n)

◆ SetInformationObject()

void vtkInformationVector::SetInformationObject ( int  index,
vtkInformation info 
)

Get/Set the vtkInformation instance stored at the given index in the vector.

The vector will automatically expand to include the index given if necessary. Missing entries in-between will be filled with empty vtkInformation instances.

◆ GetInformationObject()

vtkInformation* vtkInformationVector::GetInformationObject ( int  index)

◆ Append()

void vtkInformationVector::Append ( vtkInformation info)

Append/Remove an information object.

◆ Remove() [1/2]

void vtkInformationVector::Remove ( vtkInformation info)

◆ Remove() [2/2]

void vtkInformationVector::Remove ( int  idx)

◆ Register()

void vtkInformationVector::Register ( vtkObjectBase o)
overridevirtual

Initiate garbage collection when a reference is removed.

Reimplemented from vtkObjectBase.

◆ UnRegister()

void vtkInformationVector::UnRegister ( vtkObjectBase o)
overridevirtual

Decrease the reference count (release by another object).

This has the same effect as invoking Delete() (i.e., it reduces the reference count by 1).

Reimplemented from vtkObjectBase.

◆ Copy()

void vtkInformationVector::Copy ( vtkInformationVector from,
int  deep = 0 
)

Copy all information entries from the given vtkInformation instance.

Any previously existing entries are removed. If deep==1, a deep copy of the information structure is performed (new instances of any contained vtkInformation and vtkInformationVector objects are created).

◆ ReportReferences()

void vtkInformationVector::ReportReferences ( vtkGarbageCollector )
overrideprotectedvirtual

Reimplemented from vtkObjectBase.
