ElfPrFPRegSet

private ElfPrFPRegSet(byte[] singleNoteData,
                      Elf elf)

Method Detail

setFPRegisterBuffer

public void setFPRegisterBuffer(byte[] buffer)

Sets the FP register buffer from buffer.

Parameters:

byte[] - buffer - the ptrace byte buffer representing the block of memory the fp registers reside. As fp registers are very arch specific this is the only way we can represent in a genric way.

getFPRegisterBuffer

public byte[] getFPRegisterBuffer()

Returns the FP register info as a byte array

Returns:

- buffer of fp registers

decode

public static ElfPrFPRegSet[] decode(ElfData noteData)

getNoteData

public static long getNoteData(ElfData data)

getEntrySize

public long getEntrySize()

Specified by:

fillMemRegion

public long fillMemRegion(byte[] buffer,
                          long startAddress)

Specified by:
