Method Details

getBytes

int getBytes(long address,
 byte[] buffer,
 int offset,
 int length)
      throws MemoryFault

Reads data from the memory range

Parameters:

address - Starting address

buffer - Buffer to read into

offset - Offset in buffer to write to

length - Number of bytes to read

Returns:

Bytes read

Throws:

MemoryFault

isBacked

boolean isBacked()

Specified by:

isBacked in interface IMemoryRange

Returns:

True if this memory range is backed with data (such that getBytes() won't always throw MemoryFault).
