Detailed Description

DAG Node Function Set.

Provides methods for attaching Function Sets to, querying, and adding children to DAG Nodes. Particularly useful when used in conjunction with the DAG Iterator class (MItDag).

The MFnDagNode function set is used to query and set the attributes of nodes in the DAG (Directed Acyclic Graph). The DAG is a graph that describes the hierarchy of the objects in the model. At each level of the hierarchy there is a four by four transformation matrix that affects all of the objects beneath it in the DAG.

In the DAG, geometry objects (also known as shapes) do not have transformation information associated with them. Only transform nodes have actual transform matrices (see MFnTransform).

Each node that exists in the DAG is also a dependency node that exists in the dependency graph. This makes it possible to control the attributes of a DAG node based on calculations performed by dependency nodes.

There are two ways to specify a DAG node in Maya. The first is to use an MObject handle, which acts as a pointer to a specific node in the DAG. Given only an MObject, it is not possible to do world space operations on a DAG node because there may be more than one path through the DAG to any given node. In other words, it is not possible to identify a particular instance only given an MObject.

In many cases it is preferable to use a DAG path (MDagPath) to specify a DAG node. A DAG path always refers to a specific instance of an object. This makes it possible to perform unambiguous world space transformations.

It is also possible to iterate over the nodes in the DAG using a DAG iterator (MItDag).

MStatus MFnDagNode::addChild ( MObject &  child,
unsigned int  index = kNextPos,
bool  keepExistingParents = false 
)

Makes the given DAG Node a child of the DAG Node to which this instance of the Function Set is attached.

By default, the child will be added to the end of the child list. If an index is specified, and it is less than or equal to the upper bound, Maya will add the child to the specified index and shift the position of subsequent children onto the next position. If the index is greater than the upper bound, the behavior is undefined.

By default, the child is removed from its existing parents as a result of this operation. If the flag keepExistingParents is set to true, the child will keep its existing parents and a new instance connection will be created for the new node. Any instanced attributes downstream from the new child will be updated with new instance numbers.

Parameters:
[in] child The node to be added as child
[in] index The index that the child should be position. Defaulted to MFnDagNode::kNextPos
Returns:
Status Code
Status Codes:

MStatus MFnDagNode::removeChild ( MObject &  child  ) 

Removes the given DAG Node from the parent. Once the child is removed, all children at higher indices would shift 1 position to the left.

If the child being removed is an instance, any instance attributes downstream from the node being removed will be updated with the new instance count.

Parameters:
[in] child The Node to be removed as child
Returns:
Status Code
Status Codes:

MStatus MFnDagNode::removeChildAt ( unsigned int  index  ) 

Removes the child at the given index from the parent. Once the child is removed, all children at higher indices would shift 1 position to the left.

If the child being removed is an instance, any instance attributes downstream from the node being removed will be updated with the new instance count.

Status Codes:

MStatus MFnDagNode::setInstanceable ( const bool  how  ) 

Sets whether or not the DAG node is instanceable. If the node is marked as noninstanceable, then if Maya attempts to create instances on the node the instancing operation will not succeed and instead an error will be reported. A node cannot be marked non-instanceable if it or any of its children are currently instanced. MS::kFailure will be returned it this occurs. The default instanceable state for newly created nodes if true, meaning that nodes can be instanced by default.

Parameters:
[in] how true if the node should be made instanceable, false to make the node noninstanceable.
Returns:
Status code
Status Codes:
  • MS::kSuccess successfully set the instanceable state on the node
  • MS::kFailure function set does not have a valid node, or the node or one of its child nodes is already instanced and you are attempting to flag the node as non-instanceable, or the node is locked.

bool MFnDagNode::isInstanced ( bool  indirect = true,
MStatus *  ReturnStatus = NULL 
) const

Determines whether the DAG Node attached to the Function Set is directly or indirectly instanced.

If indirect instance flag is false, the result is true if and only if the Node itself is multiply instanced (node->parentCount > 1).

If the indirect flag is true, the result is true if and only if the Node itself is multiply instanced (node->parentCount > 1) or if the Node is not multiply instanced, but it has a directly instanced parent (node->parentCount()=1 amd parent->parentCount >1).

Parameters:
[in] indirect Indirect instance flag
[out] ReturnStatus Status Code (see below)
Returns:
Boolean value: true if the node is instanced (directly or indirectly according to indirect instance flag), false otherwise.
Status Codes:

bool MFnDagNode::isInstancedAttribute ( const MObject &  attribute,
MStatus *  ReturnStatus = NULL 
) const

Returns true if the specified attribute is instanced. An instanced attribute is an array attribute whose index depends upon which instance of the node is being referred to.

Attributes are not instanced by default.

Parameters:
[in] attribute The attribute to test.
[out] ReturnStatus Return status.
Returns:
A boolean value indicating whether the attribute is instanced
Status Codes:

unsigned int MFnDagNode::instanceCount ( bool  total,
MStatus *  ReturnStatus = NULL 
) const

Determines the number of times the Node attached to the Function Set is instanced.

If indirect instance flag is false, the number of direct instances is returned.

If the indirect flag is true, the total number of times the Node is instanced in the DAG above it is returned.

Parameters:
[in] total Indirect instance flag
[out] ReturnStatus Status Code (see below)
Returns:
Number of instances (direct or indirect according to indirect instance flag).
Status Codes:

MObject MFnDagNode::duplicate ( bool  instance = false,
bool  leafInstance = false,
MStatus *  ReturnStatus = NULL 
) const

This method duplicates the DAG hierarchy rooted at the current node. The copy will have the same parent, if any, as the original node.

If instance is false then a true copy will be made, otherwise a new node will be created which instances the child nodes of the original node. If instance is false then instanceLeaf is ignored.

If instance is true and instanceLeaf is false then the child nodes of the original node are instanced. If instanceLeaf is true, then the results are similar to a copy, but the leaf level objects are instanced.

If the function set is initialized without an MDagPath, then this method uses the first path to the node. This is only a problem if the node has been instanced, in which case the simple solution is to use an MDagPath to initialize the function set.

Parameters:
[in] instance Duplicate using instancing if true
[in] leafInstance Instance only at the leaf level if true
[out] ReturnStatus Status Code (see below)
Returns:
A reference to the newly created node.
Status Codes:
Examples:
polyModifierCmd.cpp.

MStatus MFnDagNode::getPath ( MDagPath &  path  ) 

Returns a DAG Path to the DAG Node attached to the Function Set. The difference between this method and the method dagPath below is that this one will not fail if the function set is not attached to a dag path, it will always return a path to the node. dagPath will fail if the function set is not attached to a dag path.

Parameters:
[out] path The DAG Path that is found (implicit return)
Returns:
Status Code
Status Codes:
Examples:
cgfxShaderCmd.cpp, helixTool.cpp, instanceCallbackCmd.cpp, and polyModifierCmd.cpp.

The partial path name
Status Codes:

MMatrix MFnDagNode::transformationMatrix ( MStatus *  ReturnStatus = NULL  )  const

Returns the object space transformation matrix for this DAG node. In general, only transform nodes have matrices associated with them. Nodes such as shapes (geometry nodes) do not have transform matrices.

The identity matrix will be returned if this node does not have a transformation matrix.

Parameters:
[out] ReturnStatus Status Code (see below)
Returns:
Object space transformation matrix.
Status Codes:

bool MFnDagNode::isIntermediateObject ( MStatus *  ReturnStatus = NULL  )  const

Returns true if this object is an intermediate in a geometry calculation.

When geometry calculations are performed using dependency nodes, it is sometimes necessary to use intermediate objects. These objects are not draw or rendered. For example, deformers use intermediate geometry during their calculations.

This method exists to provide a more convenient way of accessing the intermediateObject attribute of DAG nodes.

Parameters:
[out] ReturnStatus Status Code (see below)
Returns:
Boolean value determining whether this is an intermediate object
Status Codes:
Examples:
polyExporter.cpp.

MStatus MFnDagNode::setIntermediateObject ( bool  isIntermediate  ) 

Sets whether this object is an intermediate in a geometry calculation.

When geometry calculations are performed using dependency nodes, it is sometimes necessary to use intermediate objects. These objects are not draw or rendered. For example, deformers use intermediate geometry during their calculations.

This method exists to provide a more convenient way of accessing the intermediateObject attribute of DAG nodes.

Parameters:
[in] isIntermediate whether to make this an intermediate object
Returns:
Status Code
Status Codes:
Examples:
polyModifierCmd.cpp.

int MFnDagNode::objectColor ( MStatus *  ReturnStatus = NULL  )  const

Determines the index for the current user defined inactive color used by the node. Valid indices are from 0 to 7.

Returns:
Status Code
Status Codes:

bool MFnDagNode::usingObjectColor ( MStatus *  ReturnStatus = NULL  )  const

Determines whether or not the user defined inactive color will be used for the node, or whether the default inactive color will be used.
