Detailed Description

Numeric attribute function set.

MFnNumericAttribute is the function set for dependency node attributes that store one, two or three untyped numeric values. A numeric attribute supports both a "hard" maximum/minimum and a soft maximum/minimum. The soft maximum/minimum are used by the Attribute Editor as the limits on its slider, but values within the hard range can be typed in the input box.

As a convenience, MFnNumericAttribute will set the flags of child attributes as well when the flags of the parent attribute are set. This is important when creating a numeric pair or triplet. For example, if MFnNumericAttribute is used to create a 3 double attribute and the attribute is set to be keyable, then the three child attributes will also be marked as keyable.

Constructor & Destructor Documentation

MFnNumericAttribute	(	MObject &	object,
		MStatus *	ReturnStatus = `NULL`
	)

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters

[in]	object	The MObject to attach the function set to
[out]	ReturnStatus	the return status

Status Codes:

MS::kSuccess if the function set is successfully attached
MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

MFnNumericAttribute	(	const MObject &	object,
		MStatus *	ReturnStatus = `NULL`
	)

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters

[in]	object	The MObject to attach the function set to
[out]	ReturnStatus	the return status

Status Codes:

MS::kSuccess if the function set is successfully attached
MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

Member Function Documentation

MFn::Type type ( ) const

virtual

Function set type.

Return the class type : MFn::kNumericAttribute.

Returns: the class type.

Reimplemented from MFnAttribute.

const char * className ( )

static

Returns the name of this class.

Return the class name : "MFnNumericAttribute".

Returns: Name of this class.

MObject create	(	const MString &	full,
		const MString &	brief,
		MFnNumericData::Type	unitType,
		double	defaultValue = `0`,
		MStatus *	ReturnStatus = `NULL`
	)

Create a new numeric attribute and return it as an MObject.

If the attribute create is of a type that stores two or more values, then a compound attribute will be created. The names of child attributes will have "0", "1" and "2" appended to both the full and brief names. As well, each child will use the defaultValue parameter as its default.

The create method needs to be called on a per node basis. That means if you want to create and add the same attribute to multiple nodes, you need to call the create method for each node to get a unique MObject back. If you call create just once and add the attribute to multiple nodes, Maya will encounter a fatal error.

Parameters

[in]	full	the full (or long) name of the attribute
[in]	brief	the brief (or short) name of the attribute
[in]	unitType	an element of the MFnUnitAttribute::Type enum
[in]	defaultValue	the default value for the new attribute
[out]	ReturnStatus	MS::kSuccess the new attribute was created successfully MS::kFailure the new attribute was not created MS::kInvalidParameter the type parameter was invalid

Returns: An MObject representing the new attribute

MObject createPoint	(	const MString &	full,
		const MString &	brief,
		MStatus *	ReturnStatus = `NULL`
	)

Create a new point attribute and return it as an MObject.

The names of child attributes will have "x", "y" and "z" appended to both the full and brief names.

The create method needs to be called on a per node basis. That means if you want to create and add the same attribute to multiple nodes, you need to call the create method for each node to get a unique MObject back. If you call create just once and add the attribute to multiple nodes, Maya will encounter a fatal error.

They type of the created attribute will be MFnNumericData::k3Float.

Parameters

[in]	full	the full (or long) name of the attribute
[in]	brief	the brief (or short) name of the attribute
[out]	ReturnStatus	MS::kSuccess the new attribute was created successfully MS::kFailure the new attribute was not created MS::kInvalidParameter the type parameter was invalid

Returns: An MObject representing the new attribute

Examples:: AbcImport/NodeIteratorVisitorHelper.cpp, anisotropicShader/anisotropicShader.cpp, backfillShader/backfillShader.cpp, cellShader/cellShader.cpp, depthShader/depthShader.cpp, dynExprField/dynExprField.cpp, flameShader/flameShader.cpp, gammaShader/gammaShader.cpp, geomShader/geomShader.cpp, interpShader/interpShader.cpp, lavaShader/lavaShader.cpp, lightShader/lightShader.cpp, noiseShader/noiseShader.cpp, onbShader/onbShader.cpp, phongShader/phongShader.cpp, renderAccessNode/renderAccessNode.cpp, shadowMatteShader/shadowMatteShader.cpp, shiftNode/shiftNode.cpp, slopeShader/slopeShaderNode.cpp, solidCheckerShader/solidCheckerShader.cpp, and volumeShader/volumeShader.cpp.

		const MString &	brief,
		void *	defaultValue = `NULL`,
		MStatus *	ReturnStatus = `NULL`
	)

Create a new address attribute and return it as an MObject.

The create method needs to be called on a per node basis. That means if you want to create and add the same attribute to multiple nodes, you need to call the create method for each node to get a unique MObject back. If you call create just once and add the attribute to multiple nodes, Maya will encounter a fatal error.

		const MObject &	child3 = `MObject::kNullObj`,
		MStatus *	ReturnStatus = `NULL`
	)

Create a new numeric attribute and return it as an MObject.

This form of the create method allows the creation of a compound attribute having two or three numeric child attributes. All of the child attributes must be of the same type (eg all of type kDouble) and must already have been created but not yet added to the node.

It is also possible to use angle and distance attributes created with MFnUnitAttribute. These attributes will act the same as a double attribute.

[in]	brief	the brief (or short) name of the attribute
[in]	child1	a numeric attribute
[in]	child2	a numeric attribute
[in]	child3	a numeric attribute (optional)
[out]	ReturnStatus	MS::kSuccess the new attribute was created successfully MS::kFailure the new attribute was not created MS::kInvalidParameter the given child objects were not all numeric attributes or one or more of them has already been added to the node

Returns: An MObject representing the new attribute
