Detailed Description

single entry switch variable that can take a range of values

Member Function Documentation

◆ initializeForReading()

bool ghidra::JumpValuesRange::initializeForReading ( void  ) const
virtual

Initialize this for iterating over the set of possible values.

Returns
true if there are any values to iterate over

Implements ghidra::JumpValues.

Reimplemented in ghidra::JumpValuesRangeDefault.

Referenced by ghidra::JumpBasic::buildLabels().

◆ truncate()

void ghidra::JumpValuesRange::truncate ( int4  nm)
virtual

The starting value for the range and the step is preserved. The ending value is set so there are exactly the given number of elements in the range.

Parameters
nmis the given number

Implements ghidra::JumpValues.
