Help on built-in function addAttribute:
addAttribute(...)
addAttribute(attr) -> None
This method adds a new attribute to a user defined node type during the type's initialization.
This method will only work during the static initialization method of the user defined node class. The initialization method is the one that is passed into MFnPlugin.registerNode(). The attributes must first be created using one of the MFnAttribute classes, and can then be added using this method.
For compound attributes, the proper way to use this method is by calling it with the parent attribute. If a compound attribute is passed, this method will add all of its children.
NOTE: A failure will occur if you attempt to call addAttribute() on the children of a compound attribute.
* attr (MObject) - new attribute to add.

Help on built-in function addExternalContentForFileAttr:
addExternalContentForFileAttr(...)
addExternalContentForFileAttr(table, attr) -> bool
This method is a helper for derived clases implementing getExternalContent(). It augments the external content info table passed in with an entry describing external content whose location is described by the specified attribute.
The method will not overwrite existing items, i.e. items with the same key. (attribute name). In this context, overwriting an item means the caller has called this function twice with the same attribute, or that two separate but identically named attributes were used. If replacing an entry is the desired effect, it is the caller's responsibility to erase the previous item first.
* table [OUT] (MExternalContentInfoTable) - table The table in which the new entry will be added.
* attr (MObject) - The attribute for which the plug value will be queried for a location.
Returns True if an item was sucessfully added to the table. False if the attribute does not describe a non-empty location, or an item with the same key was already present in the table.

Help on built-in function attributeAffects:
attributeAffects(...)
attributeAffects(whenChanges, isAffected) -> None
This method specifies that a particular input attribute affects a specific output attribute. This is required to make evaluation efficient. When an input changes, only the affected outputs will be computed. Output attributes cannot be keyable - if they are keyable, this method will fail.
This method must be called for every attribute dependency when initializing the node's attributes. The attributes must first be added using the MPxNode.addAttribute() method. Failing to call this method will cause the node not to update when its inputs change. If there are no calls to this method in a node's initialization, then the compute method will never be called.
This method will only work during the static initialization method of the user defined node class. The initialization method is the one that is passed into MFnPlugin.registerNode(). As a result, it does not work with dynamic attributes. For an alternate solution which handles dynamic as well as non-dynamic attributes refer to MPxNode.setDependentsDirty.()

Help on built-in function compute:
compute(...)
compute(plug, dataBlock) -> self
This method should be overridden in user defined nodes.
Recompute the given output based on the nodes inputs. The plug represents the data value that needs to be recomputed, and the data block holds the storage for all of the node's attributes.
The MDataBlock will provide smart handles for reading and writing this node's attribute values. Only these values should be used when performing computations.
When evaluating the dependency graph, Maya will first call the compute method for this node. If the plug that is provided to the compute indicates that that the attribute was defined by the Maya parent node, the compute method should return None. When this occurs, Maya will call the internal Maya node from which the user-defined node is derived to compute the plug's value.
This means that a user defined node does not need to be concerned with computing inherited output attributes. However, if desired, these can be safely recomputed by this method to change the behaviour of the node.

Help on built-in function setDependentsDirty:
setDependentsDirty(...)
setDependentsDirty(plug, plugArray) -> self
This method can be overridden in user defined nodes to specify which plugs should be set dirty based upon an input plug which Maya is marking dirty. The list of plugs for Maya to mark dirty is returned by the plug array. This method handles both dynamic as well as non-dynamic plugs and is useful in the following ways:
- Allows attributeAffects-style relationships to be handled for dynamically-added attributes. Since MPxNode.attributeAffects() can only be used with non-dynamic attributes, use of this method allows a way for all attributes of a node to affect one another, both dynamic and non-dynamic.
- Provides more flexible relationships than what is available with MPxNode.attributeAffects(). For example, you may wish to not dirty plugs when the current frame is one. However, as the routine is called during dirty propagation, there are restrictions on what can be done within the routine, most importantly you must not cause any dependency graph computation. For details, see the IMPORTANT NOTE below.
This method is designed to work harmoniously with MPxNode.attributeAffects() on the same node. Alternately, you can do all affects relationships within a yourNode.setDependentsDirty() implementation.
The body of a user-implemented setDependentsDirty() implementation might look like the following example, which causes the plug called "B" to be set dirty whever plug "A" is changed, i.e. A affects B.
* plug (MPlug) - plug which is being set dirty by Maya.

shouldSave(plug) -> bool/None
This method may be overridden by the user defined node. It should only be required to override this on rare occasions.
This method determines whether a specific attribute of this node should be written out during a file save. The default behavior is to only write the value if it differs from the default and is not being supplied by a connection. This behavior should be sufficient in most cases.
This method is not called for ramp attributes since they should always be written.
* plug (MPlug) - plug representing the attribute to be saved.

Help on built-in function type:
type(...)
type() -> int
Returns the type of node that this is. This is used to differentiate user defined nodes that are derived off different MPx base classes.
It is not necessary to override this method.
