PDG_AttributeData::PDG_AttributeData ( )

Constructs a new instance with a specified type and owning map, called by child classes.

virtual PDG_AttributeData::~PDG_AttributeData ( )

virtual

Member Function Documentation

virtual PDG_AttributeData* PDG_AttributeData::clone ( ) const

pure virtual

Deep copies this attribute.

Implemented in PDG_AttributeFile, PDG_AttributeArraySimple< AttribType, DataType, ArrayType, JSONType >, PDG_AttributePyObject, and PDG_AttributeGeometry.

virtual bool PDG_AttributeData::compare ( const PDG_AttributeData * ) const

pure virtual

Compares this data object with another data object.

Implemented in PDG_AttributeArray< AttribType, DataType, ArrayType >, PDG_AttributeArray< PDG_AttributeType::eFileArray, PDG_File, PDG_File::Array >, PDG_AttributePyObject, and PDG_AttributeGeometry.

static PDG_EventType PDG_AttributeData::eventType ( PDG_AttributeType type )

static

Static utility for returnign an event from type from an attribute type.

static PDG_AttributeData* PDG_AttributeData::fromType ( PDG_AttributeType type )

static

Static utility for constructing an attribute of the specified type, used during deserialization

virtual int64 PDG_AttributeData::getMemoryUsage ( bool inclusive ) const

pure virtual

Returns the memory usage of the attribute and its data.

Implemented in PDG_AttributeFile, PDG_AttributeArraySimple< AttribType, DataType, ArrayType, JSONType >, PDG_AttributePyObject, and PDG_AttributeGeometry.

virtual bool PDG_AttributeData::hash	(	SYS_HashType &	hash_value,
		UT_WorkBuffer &	errors
	)		const

pure virtual

Return a hash value derived from the attribute data.

Implemented in PDG_AttributeArray< AttribType, DataType, ArrayType >, PDG_AttributeArray< PDG_AttributeType::eFileArray, PDG_File, PDG_File::Array >, PDG_AttributePyObject, and PDG_AttributeGeometry.

static PDG_AttributeIntrinsic PDG_AttributeData::intrinsicFromName ( const UT_StringRef & name )

static

Returns an intrinsic type from an attribue name.

virtual bool PDG_AttributeData::loadData ( const UT_JSONValue & )

pure virtual

Loads data from a JSON value.

Implemented in PDG_AttributeFile, PDG_AttributeArraySimple< AttribType, DataType, ArrayType, JSONType >, PDG_AttributePyObject, and PDG_AttributeGeometry.

static bool PDG_AttributeData::makeValidName	(	UT_StringHolder &	name,
		const UT_StringHolder &	str,
		bool	allow_internal = `false`
	)

static

Forces the string into a valid attribute name as described above, and returns true if any changes were made. If allow_internal is false then a __pdg prefix is replaced with __.

virtual PDG_AttributeMergeError PDG_AttributeData::merge	(	PDG_AttributeMergeOp	merge_op,
		int	stride
	)

pure virtual

Applies a merge op to the data in this attribute.

Implemented in PDG_AttributeArray< AttribType, DataType, ArrayType >, PDG_AttributeArray< PDG_AttributeType::eFileArray, PDG_File, PDG_File::Array >, PDG_AttributePyObject, and PDG_AttributeGeometry.

static PDG_AttributeMergeError PDG_AttributeData::merge	(	UT_StringArray &	data,
		PDG_AttributeMergeOp	merge_op,
		int	stride
	)

staticprotected

Merge op utility for string array data.

static PDG_AttributeMergeError PDG_AttributeData::merge	(	PDG_File::Array &	data,
		PDG_AttributeMergeOp	merge_op,
		int	stride
	)

staticprotected

Merge op utility for file array data.

static PDG_AttributeMergeError PDG_AttributeData::merge	(	UT_ValArray< fpreal > &	data,
		PDG_AttributeMergeOp	merge_op,
		int	stride
	)

staticprotected

Merge op utility for float array data.

static PDG_AttributeMergeError PDG_AttributeData::merge	(	UT_ValArray< exint > &	data,
		PDG_AttributeMergeOp	merge_op,
		int	stride
	)

staticprotected

Merge op utility for int array data.

static UT_StringHolder PDG_AttributeData::mergeName ( PDG_AttributeMergeOp merge )

static

Returns the string name for the specified merge op.

static UT_StringHolder PDG_AttributeData::nameFromIntrinsic	(	PDG_AttributeIntrinsic	attrib_type,
		const UT_StringHolder &	name
	)

static

Returns an attribute name from a intrinsic type a name string.

virtual bool PDG_AttributeData::saveData ( UT_JSONWriter & ) const

pure virtual

Serializes the data to a JSON writer.

Implemented in PDG_AttributeFile, PDG_AttributeArraySimple< AttribType, DataType, ArrayType, JSONType >, PDG_AttributePyObject, and PDG_AttributeGeometry.

static PDG_AttributeType PDG_AttributeData::typeFromString ( const UT_StringHolder & type_name )

static

Returns an attribute type enum from the specified string name.

static UT_StringHolder PDG_AttributeData::typeName ( PDG_AttributeType type )

static

Returns the string name for the specififed attribute type.

static bool PDG_AttributeData::validName	(	const UT_StringHolder &	str,
		bool	allow_internal = `false`
	)

static

Returns true if the specified string is a valid attribute name. A valid name cannot start with __pdg prefix unless allow_interal is true. All names must begin with a letter or _ character and only contain letters/numbers/_ for subsequent character. E.g. they must match UT_String::isValidVariableName.
