hou.DopDataType class

Describes the type of data in a DOP object.

Not implemented yet

See hou.DopData.dataTypeObject for a function that retrieves a DopDataType instance from a hou.DopData instance. Note that not all DOP data type names have a corresponding DopDataType instance.

Methods

name(self)

Not implemented yet

Return the name of this data type.

>>> obj = hou.node("/obj/AutoDopNetwork").simulation().objects()[0]
>>> obj.dataTypeObject().name()
'SIM_Object'
nodeType(self) → hou.NodeType

Not implemented yet

Return the DOP node type that creates this DOP data type. 

>>> hou.dop.findDataType("SIM_SDF").nodeType()
<hou.NodeType for Dop volume>

allowedChildData(self) → tuple of hou.DopDataType

Not implemented yet

Return a tuple of DopDataTypes that are allowed to be attached as subdata to instances of this data type.

These allowed child data types give hints to Houdini to prevent you from accidentally building DOP networks that attach DOP data to the wrong location. Houdini will validate the network and flag possible mistakes when the “Provide Data Hints” option is on.

Houdini also uses this information to decide how many data inputs to display on DOP nodes and how to label those inputs.

The default data hints are stored in $HFS/houdini/scripts/dophints.cmd.

maxNumAllowedChildData(self, type) → int or None

Not implemented yet

Given a DopDataType, return the maximum number of allowed children of that type, or None if there is no maximum. If the type is not allowed at all, return 0.

See also hou.DopDataType.allowedChildData and hou.DopDataType.allowedChildDataName.

allowedChildDataName(self, type) → str or None

Not implemented yet

Given a DopDataType, return what any subdata of that type must be named, or None if there is no name restriction.

See also hou.DopDataType.allowedChildData and hou.DopDataType.maxNumAllowedChildData.

addAllowedChildData(self, dop_data_type, max_num=None, child_name=None)

Not implemented yet

Allow a DOP data type to be a child of this one, with possible restrictions.

max_num

If not None, the maximum allowed number of children of this type. If None, there is no maximum.

child_name

If not None, the subdata must have this name when added as a child. If None, there are no name restrictions.

See hou.DopDataType.allowedChildData for more information.

removeAllowedChildData(self, dop_data_type)

Not implemented yet

No longer allow a particular DOP data type to be a child of this one. See hou.DopDataType.allowedChildData and hou.DopDataType.addAllowedChildData for more information.
