PDG_AttributeInfo::PDG_AttributeInfo | ( | ) |
Default attribute origins are initialized to static.
Adds attributes that are consumed by this object.
Adds the attributes from the maap to the output map of this object.
void PDG_AttributeInfo::addUpstreamAttribs | ( | const PDG_AttributeInfo & | info, |
bool | dynamic_generator | ||
) |
Adds the input attributes from the attribute info to the input map of this object
bool PDG_AttributeInfo::checkNeedsDynamic | ( | bool | require_inputs | ) | const |
Returns true if the node needs to be dynamic in order to access the attributes it needs to generate.
|
static |
Loads a Config object from a JSON array.
Returns the attributes referenced or use during the current cook.
Definition at line 95 of file PDG_AttributeInfo.h.
Returns the output attribute map, i.e. attributes produced by the node that owns this object
Definition at line 91 of file PDG_AttributeInfo.h.
void PDG_AttributeInfo::processExpressionAttribs | ( | const PDG_NodeInterface * | node_interface, |
const UT_ArrayStringMap< int > & | ports | ||
) |
Copies expression attributes to inputs based on the port map.
void PDG_AttributeInfo::reset | ( | ) |
Resets the internal structures of this object. Called during a cook, so the info can be re-filled from the inputs, node options and parms
Returns the upstream attribute map, i.e. the total set of all upstream attributes that might be available to work items in this node.
