Detailed Description

Superclass for vtkInformation keys.

vtkInformationKey is the superclass for all keys used to access the map represented by vtkInformation. The vtkInformation::Set and vtkInformation::Get methods of vtkInformation are accessed by information keys. A key is a pointer to an instance of a subclass of vtkInformationKey. The type of the subclass determines the overload of Set/Get that is selected. This ensures that the type of value stored in a vtkInformation instance corresponding to a given key matches the type expected for that key.

Constructor & Destructor Documentation

vtkInformationKey::vtkInformationKey ( const char *  name,
const char *  location 
)

Key instances are static data that need to be created and destroyed. The constructor and destructor must be public. The name of the static instance and the class in which it is defined should be passed to the constructor. They must be string literals because the strings are not copied.

vtkInformationKey::~vtkInformationKey ( )

Key instances are static data that need to be created and destroyed. The constructor and destructor must be public. The name of the static instance and the class in which it is defined should be passed to the constructor. They must be string literals because the strings are not copied.

Prevent normal vtkObject reference counting behavior.

Reimplemented from vtkObjectBase.

virtual void vtkInformationKey::UnRegister ( vtkObjectBase )
virtual

Prevent normal vtkObject reference counting behavior.

Reimplemented from vtkObjectBase.

const char* vtkInformationKey::GetName ( )

Get the name of the key. This is not the type of the key, but the name of the key instance.

const char* vtkInformationKey::GetLocation ( )

Get the location of the key. This is the name of the class in which the key is defined.

virtual void vtkInformationKey::ShallowCopy ( vtkInformation from,
vtkInformation to 
)
pure virtual
virtual void vtkInformationKey::DeepCopy ( vtkInformation from,
vtkInformation to 
)
inlinevirtual

Duplicate (new instance created) the entry associated with this key from one information object to another (new instances of any contained vtkInformation and vtkInformationVector objects are created). Default implementation simply calls ShallowCopy().

Reimplemented in vtkInformationQuadratureSchemeDefinitionVectorKey, vtkInformationInformationKey, and vtkInformationInformationVectorKey.

Definition at line 77 of file vtkInformationKey.h.

virtual int vtkInformationKey::Has ( vtkInformation info)
virtual

Check whether this key appears in the given information object.

Reimplemented in vtkInformationRequestKey.

virtual void vtkInformationKey::Remove ( vtkInformation info)
virtual

Remove this key from the given information object.

Reimplemented in vtkInformationExecutivePortVectorKey, and vtkInformationRequestKey.

virtual void vtkInformationKey::Report ( vtkInformation info,
vtkGarbageCollector collector 
)
virtual
void vtkInformationKey::Print ( vtkInformation info)

Print the key's value in an information object to a stream.

virtual void vtkInformationKey::Print ( ostream &  os,
vtkInformation info 
)
virtual
virtual bool vtkInformationKey::NeedToExecute ( vtkInformation vtkNotUsedpipelineInfo,
vtkInformation vtkNotUseddobjInfo 
)
inlinevirtual

This function is only relevant when the pertaining key is used in a VTK pipeline. Specific keys that handle pipeline data requests (for example, UPDATE_PIECE_NUMBER) can overwrite this method to notify the pipeline that a a filter should be (re-)executed because what is in the current output is different that what is being requested by the key. For example, DATA_PIECE_NUMBER != UPDATE_PIECE_NUMBER.

Definition at line 103 of file vtkInformationKey.h.

virtual void vtkInformationKey::StoreMetaData ( vtkInformation vtkNotUsedrequest,
vtkInformation vtkNotUsedpipelineInfo,
vtkInformation vtkNotUseddobjInfo 
)
inlinevirtual

This function is only relevant when the pertaining key is used in a VTK pipeline. Specific keys that handle pipeline data requests (for example, UPDATE_PIECE_NUMBER) can overwrite this method to store in the data information meta-data about the request that led to the current filter execution. This meta-data can later be used to compare what is being requested to decide whether the filter needs to re-execute. For example, a filter may store the current UPDATE_PIECE_NUMBER in the data object's information as the DATA_PIECE_NUMBER. DATA_PIECE_NUMBER can later be compared to a new UPDATA_PIECE_NUMBER to decide whether a filter should re-execute.

Definition at line 118 of file vtkInformationKey.h.

virtual void vtkInformationKey::CopyDefaultInformation ( vtkInformation vtkNotUsedrequest,
vtkInformation vtkNotUsedfromInfo,
vtkInformation vtkNotUsedtoInfo 
)
inlinevirtual

This function is only relevant when the pertaining key is used in a VTK pipeline. By overwriting this method, a key can decide if/how to copy itself downstream or upstream during a particular pipeline pass. For example, meta-data keys can copy themselves during REQUEST_INFORMATION whereas request keys can copy themselves during REQUEST_UPDATE_EXTENT.
