Detailed Description

Serialize/deserialize vtkCellMetadata records.

vtkCellGridIOQuery is a concrete subclass of vtkCellGridQuery that helps serialize/deserialize vtkCellGrid objects to/from JSON. Specifically, it reads/writes data specific to subclasses of vtkCellMetadata.

◆ IsTypeOf()

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

◆ IsA()

virtual vtkTypeBool vtkCellGridIOQuery::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 vtkCellGridQuery.

◆ SafeDownCast()

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

◆ NewInstanceInternal()

virtual vtkObjectBase * vtkCellGridIOQuery::NewInstanceInternal ( ) const

◆ NewInstance()

vtkCellGridIOQuery * vtkCellGridIOQuery::NewInstance ( ) const

◆ PrintSelf()

void vtkCellGridIOQuery::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.

◆ PrepareToDeserialize()

void vtkCellGridIOQuery::PrepareToDeserialize ( const nlohmann::json &  sourceData,
const nlohmann::json &  attributeData,
std::vector< vtkCellAttribute * > &  attributeList 
)

Prepare to deserialize cell metadata from the given sourceData JSON object.

Note that sourceData, attributeData, and attributeList must be kept alive for the duration of the query's execution; the query only references them (rather than copying them).

◆ PrepareToSerialize()

void vtkCellGridIOQuery::PrepareToSerialize ( nlohmann::json &  destination,
nlohmann::json &  attributeData,
const std::unordered_map< vtkAbstractArray *, vtkStringToken > &  arrayLocations 
)

Prepare to serialize cell metadata to the given parent JSON object.

◆ GetData()

nlohmann::json * vtkCellGridIOQuery::GetData ( )
inline

Return the JSON object that holds attribute data.

Definition at line 63 of file vtkCellGridIOQuery.h.

◆ GetAttributeData()

nlohmann::json * vtkCellGridIOQuery::GetAttributeData ( )
inline

Return the JSON object that holds attribute data.

Definition at line 66 of file vtkCellGridIOQuery.h.

◆ GetArrayLocations() [1/2]

const std::unordered_map< vtkAbstractArray *, vtkStringToken > & vtkCellGridIOQuery::GetArrayLocations ( ) const
inline

Return the map of array pointers to the names of groups which contain them.

Definition at line 69 of file vtkCellGridIOQuery.h.

◆ GetArrayLocations() [2/2]

std::unordered_map< vtkAbstractArray *, vtkStringToken > & vtkCellGridIOQuery::GetArrayLocations ( )
inline

Return the JSON object that holds attribute data.

Definition at line 73 of file vtkCellGridIOQuery.h.

◆ GetAttributeList()

const std::vector< vtkCellAttribute * > & vtkCellGridIOQuery::GetAttributeList ( ) const
inline

Return a vector of cell-attributes that matches AttributeData.

Definition at line 79 of file vtkCellGridIOQuery.h.

◆ IsSerializing()

bool vtkCellGridIOQuery::IsSerializing ( ) const
inline

Return true if the query is serializing cells (as opposed to deserializing).

Definition at line 82 of file vtkCellGridIOQuery.h.

◆ ExtractCellTypeAttributeInfo()

bool vtkCellGridIOQuery::ExtractCellTypeAttributeInfo ( vtkCellGrid grid,
vtkCellAttribute::CellTypeInfo cellTypeInfo,
const nlohmann::json &  jsonInfo,
vtkStringToken  cellTypeName 
)

Extract JSON array information into vtkCellAttribute::CellTypeInfo.

This is a helper intended to be called by responders. It extracts data from jsonInfo specific to cellType into the cellTypeInfo you pass in.

The jsonInfo object point to data for one cell-attribute's "cell-info" key.

◆ InsertCellTypeAttributeInfo()

bool vtkCellGridIOQuery::InsertCellTypeAttributeInfo ( vtkCellGrid grid,
const vtkCellAttribute::CellTypeInfo cellTypeInfo,
nlohmann::json &  jsonInfo,
vtkStringToken  cellTypeName 
)

Insert vtkCellAttribute::CellTypeInfo into the given jsonInfo object for the given cellTypeName.

This is a helper intended to be called by responders to insert the base CellTypeInfo data into jsonInfo. If subclasses of vtkCellMetadata ever insert subclasses of CellTypeInfo (not currently supported), then they will also need to add information specific to the subclass.

◆ AddMetadataEntry()

nlohmann::json & vtkCellGridIOQuery::AddMetadataEntry ( vtkStringToken  cellTypeName)

Add a metadata entry for cellTypeName to the output.
