Package ghidra.pcode.exec

Interface PcodeUseropLibrary.PcodeUseropDefinition<T>

Type Parameters:

T - the type of parameter accepted (and possibly returned) by the userop.

All Known Implementing Classes:

AnnotatedPcodeUseropLibrary.AnnotatedPcodeUseropDefinition, AnnotatedPcodeUseropLibrary.FixedArgsAnnotatedPcodeUseropDefinition, AnnotatedPcodeUseropLibrary.VariadicAnnotatedPcodeUseropDefinition, EmuSyscallLibrary.SyscallPcodeUseropDefinition, SleighPcodeUseropDefinition

Enclosing interface:

PcodeUseropLibrary<T>

public static interface PcodeUseropLibrary.PcodeUseropDefinition<T>

The definition of a p-code userop.

Method Summary

Modifier and Type	Method	Description
void	execute(PcodeExecutor<T> executor, PcodeUseropLibrary<T> library, Varnode outVar, List<Varnode> inVars)	Invoke/execute the userop.
int	getInputCount()	Get the number of input operands acccepted by the userop.
String	getName()	Get the name of the userop.

Method Details

getName

String getName()

Get the name of the userop.

This is the symbol assigned to the userop when compiling new Sleigh code. It cannot conflict with existing userops (except those declared, but not defined, by the executor's language) or other symbols of the executor's language. If this userop is to be used generically across many languages, choose an unlikely name. Conventionally, these start with two underscores __.

Returns:

the name of the userop

getInputCount

int getInputCount()

Get the number of input operands acccepted by the userop.

Returns:

the count or -1 if the userop is variadic

execute

void execute(PcodeExecutor<T> executor,
 PcodeUseropLibrary<T> library,
 Varnode outVar,
 List<Varnode> inVars)

Invoke/execute the userop.

Parameters:

executor - the executor invoking this userop.

library - the complete library for this execution. Note the library may have been composed from more than the one defining this userop.

outVar - if invoked as an rval, the destination varnode for the userop's output. Otherwise, null.

inVars - the input varnodes as ordered in the source.
