Method Detail

create

public void create(Address addr,
                   DwarfEHDecoder decoder,
                   long fdeTableCnt)
            throws MemoryAccessException,
                   ExceptionHandlerFrameException

Creates an FDE Table at the specified Address.

Parameters:

addr - Address at which the FDE Table should be created.

decoder - the decoder for DWARF encoded exception handling information
