Detailed Description

Store vtkAlgorithm input/output information.

vtkInformation represents information and/or data for one input or one output of a vtkAlgorithm. It maps from keys to values of several data types. Instances of this class are collected in vtkInformationVector instances and passed to vtkAlgorithm::ProcessRequest calls. The information and data referenced by the instance on a particular input or output define the request made to the vtkAlgorithm instance.

Member Function Documentation

◆ New()

static vtkInformation * vtkInformation::New ( )

static

◆ IsTypeOf()

static vtkTypeBool vtkInformation::IsTypeOf ( const char * type )

static

◆ IsA()

virtual vtkTypeBool vtkInformation::IsA ( const char * name )

virtual

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.

◆ SafeDownCast()

static vtkInformation * vtkInformation::SafeDownCast ( vtkObjectBase * o )

static

◆ NewInstanceInternal()

virtual vtkObjectBase * vtkInformation::NewInstanceInternal ( ) const

protectedvirtual

◆ NewInstance()

vtkInformation * vtkInformation::NewInstance ( ) const

◆ PrintSelf()

void vtkInformation::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.

◆ PrintKeys()

void vtkInformation::PrintKeys	(	ostream &	os,
		vtkIndent	indent
	)

◆ Modified() [1/2]

void vtkInformation::Modified ( )

overridevirtual

Modified signature with no arguments that calls Modified on vtkObject superclass.

Reimplemented from vtkObject.

◆ Modified() [2/2]

void vtkInformation::Modified ( vtkInformationKey * key )

Modified signature that takes an information key as an argument.

Sets the new MTime and invokes a modified event with the information key as call data.

◆ Clear()

void vtkInformation::Clear ( )

Clear all information entries.

◆ GetNumberOfKeys()

int vtkInformation::GetNumberOfKeys ( )

Return the number of keys in this information object (as would be returned by iterating over the keys).

◆ Copy()

void vtkInformation::Copy	(	vtkInformation *	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).

◆ Append() [1/19]

void vtkInformation::Append	(	vtkInformation *	from,
		int	deep = `0`
	)

Append all information entries from the given vtkInformation instance.

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