  • Method Details

    • clearCache

      void clearCache()
      Called when the memory map is re-initializing. Usually after an undo or redo.
    • getByte

      byte getByte(Address addr) throws MemoryAccessException
      Gets the byte at the given address.
      Parameters:
      addr - the address of the byte to be retrieved
      Returns:
      the byte at the given address.
      Throws:
      MemoryAccessException - if the byte can't be read.
    • getBytes

      int getBytes(Address address, byte[] buffer, int startIndex, int size) throws MemoryAccessException
      Get the bytes at the given address and size and put them into the destination buffer.
      Parameters:
      address - the address of the first byte to be retrieved.
      buffer - the byte buffer in which to place the bytes.
      startIndex - the starting index in the buffer to put the first byte.
      size - the number of bytes to retrieve and put in the buffer.
      Returns:
      the number of bytes placed into the given buffer.
      Throws:
      MemoryAccessException - if the bytes can't be read.
    • putByte

      void putByte(Address address, byte value) throws MemoryAccessException
      Writes the given byte value to the address in memory.
      Parameters:
      address - the address whose byte is to be updated to the new value.
      value - the value to set at the given address.
      Throws:
      MemoryAccessException - if the value can not be written to the memory.
    • putBytes

      int putBytes(Address address, byte[] source, int startIndex, int size) throws MemoryAccessException
      Writes the given bytes to memory starting at the given address.
      Parameters:
      address - the address in memory to write the bytes.
      source - the buffer containing the byte values to be written to memory.
      startIndex - the starting index in the buffer to get byte values.
      size - the number of bytes to write to memory.
      Returns:
      the number of bytes written to memory.
      Throws:
      MemoryAccessException - if the bytes can't be written to memory.
    • addLiveMemoryListener

      void addLiveMemoryListener(LiveMemoryListener listener)
      Adds a LiveMemoryListener to this handler. The listener will be notified when memory bytes change.
      Parameters:
      listener - the listener to be notified of memory byte value changes.
    • removeLiveMemoryListener

      void removeLiveMemoryListener(LiveMemoryListener listener)
      Removes the LiveMemoryListener from this handler.
      Parameters:
      listener - the listener to be removed.
