Member Function Documentation

◆ compareByHigh()

bool ghidra::PcodeOpNode::compareByHigh ( const PcodeOpNode &  a,
const PcodeOpNode &  b 
)
inlinestatic

Compare Varnodes by their HighVariable.

Allow a sorting that groups together input Varnodes with the same HighVariable

Parameters
ais the first Varnode to compare
bis the second Varnode to compare
Returns
true is a should come before b

◆ operator<()

bool ghidra::PcodeOpNode::operator< ( const PcodeOpNode &  op2) const
inline

Simple comparator for putting edges in a sorted container.

Compare PcodeOps (as pointers) first, then slot

Parameters
op2is the other edge to compare with this
Returns
true if this should come before the other PcodeOp
