Interface NativeImagePatcher

All Known Implementing Classes:

AMD64NativeImagePatcher

public interface NativeImagePatcher

Patcher used during native image runtime.

Method Summary

Modifier and Type	Method and Description
int	getLength() The length of the value to patch in bytes, e.g., the size of an operand.
int	getOffset() The position from the beginning of the method where the patch is applied.
void	patchCode(long methodStartAddress, int relative, byte[] code) Patch directly in the code buffer with an offset relative to the start of this instruction.

Method Detail

patchCode

void patchCode(long methodStartAddress,
               int relative,
               byte[] code)

Patch directly in the code buffer with an offset relative to the start of this instruction.

Parameters:

methodStartAddress - address of method start within runtime installed code

relative - pc-relative offset

code - machine code generated for this method

getOffset

int getOffset()

The position from the beginning of the method where the patch is applied. This offset is used in the reference map.

getLength

int getLength()

The length of the value to patch in bytes, e.g., the size of an operand.
