Detailed Description

An iterator over values a switch variable can take.

This iterator is intended to provide the start value for emulation of a jump-table model to obtain the associated jump-table destination. Each value can be associated with a starting Varnode and PcodeOp in the function being emulated, via getStartVarnode() and getStartOp().

Member Function Documentation

clone()

virtual JumpValues * ghidra::JumpValues::clone ( void  ) const

pure virtual

Return the number of values the variables can take.

Implemented in ghidra::JumpValuesRange, and ghidra::JumpValuesRangeDefault.

getStartOp()

virtual PcodeOp * ghidra::JumpValues::getStartOp ( void  ) const

pure virtual

Get the PcodeOp associated with the current value.

Implemented in ghidra::JumpValuesRange, and ghidra::JumpValuesRangeDefault.

getStartVarnode()

virtual Varnode * ghidra::JumpValues::getStartVarnode ( void  ) const
