bool OP_InputChangeHelper::checkChangedSourceFlags ( const OP_Node node,
unsigned  idx,
bool &  changed 

Similar to useInput() except it doesn't affect the flags. It's used to simply query whether the given input has changed. Returns false if there's errors on the input. "changed" is updated.

int64 OP_InputChangeHelper::getMemoryUsage ( bool  inclusive) const

void OP_InputChangeHelper::inputConnectChanged ( const OP_Node node,
int  which_input 

Mark the given input as dirty. NOTE: Users of this class should override OP_Node::inputConnectChanged() to call this.

void OP_InputChangeHelper::resetChangedSourceFlags ( )

Mark all inputs as dirty. This is the default.

Definition at line 39 of file OP_InputChangeHelper.h.

bool OP_InputChangeHelper::useInput ( const OP_Node node,
unsigned  idx,
bool &  changed,
bool  force 

Use the given input on the node. This updates source flags to mark the input as now clean, returning whether the input changes. If force is true, then we treat the input as always dirty. Returns false if input has errors and we'll add an input error in that case.
