Method Detail

loadMemory

protected byte[] loadMemory(int size)

Description copied from class: ObjectMemoryLoader

Loads the 'memory' component of the object memory from the input stream.

Overrides:

loadMemory in class ObjectMemoryLoader

Parameters:

size - the size of memory as specified by the 'size' element of the objct memory

Returns:

the contents of the 'memory' component

getHash

protected int getHash(byte[] dummy)

Description copied from class: ObjectMemoryLoader

Calculates the hash of an array of bytes.

Overrides:

getHash in class ObjectMemoryLoader

Parameters:

dummy - the byte array to hash

Returns:

the hash of arr

skipMemoryPadding

protected void skipMemoryPadding(String parentURI,
                                 int memorySize)

Description copied from class: ObjectMemoryLoader

Skips the padding that precedes the 'memory' item to ensure that it is word aligned with respect to the start of the object memory file.

Overrides:

skipMemoryPadding in class ObjectMemoryLoader

Parameters:

parentURI - the value of the 'parent_uri' item in the object memory file

memorySize - the value of the 'size' item in the object memory file

relocateMemory

protected Address relocateMemory(ObjectMemory parent,
                                 byte[] buffer,
                                 BitSet oopMap)

Description copied from class: ObjectMemoryLoader

Relocates the memory.

Overrides:

relocateMemory in class ObjectMemoryLoader

Parameters:

parent - the loaded/resolved parent object memory

buffer - the contents of the 'memory' component

oopMap - the bit set encapsulating the 'oopmap' component

Returns:

the address of the relocated memory buffer

loadOopMap

protected BitSet loadOopMap(int size)

Description copied from class: ObjectMemoryLoader

Loads the 'oopmap' component of the object memory from the input stream.

Overrides:

loadOopMap in class ObjectMemoryLoader

Parameters:

size - the size of memory as specified by the 'size' element of the objct memory

Returns:

the bit set encapsulating the oop map

getByte
