Parameters:: src - The object into which the new reference will be stored; slot - The address into which the new reference will be stored.; value - The value of the new short; metaDataA - A value that assists the host VM in creating a store; metaDataB - A value that assists the host VM in creating a store; mode - The context in which the store occurred

shortBulkCopy

public boolean shortBulkCopy(ObjectReference src,
                             Offset srcOffset,
                             ObjectReference dst,
                             Offset dstOffset,
                             int bytes)

Description copied from class: MutatorContext

A number of shorts are about to be copied from object src to object dst (as in an array copy). Thus, dst is the mutated object. Take appropriate write barrier actions.

Overrides:: shortBulkCopy in class MutatorContext

Parameters:: src - The source array; srcOffset - The starting source offset; dst - The destination array; dstOffset - The starting destination offset; bytes - The number of bytes to be copied
Returns:: True if the update was performed by the barrier, false if left to the caller (always false in this case).

wordWrite

public void wordWrite(ObjectReference src,
                      Address slot,
                      Word value,
                      Word metaDataA,
                      Word metaDataB,
                      int mode)

Write a Word. Take appropriate write barrier actions.

Overrides:: wordWrite in class MutatorContext

Parameters:: src - The object into which the new reference will be stored; slot - The address into which the new reference will be stored.; value - The value of the new Word; metaDataA - A value that assists the host VM in creating a store; metaDataB - A value that assists the host VM in creating a store; mode - The context in which the store occurred

wordTryCompareAndSwap

public boolean wordTryCompareAndSwap(ObjectReference src,
                                     Address slot,
                                     Word old,
                                     Word value,
                                     Word metaDataA,
                                     Word metaDataB,
                                     int mode)

Description copied from class: MutatorContext

Attempt to atomically exchange the value in the given slot with the passed replacement value. By default do nothing, override if appropriate.

Overrides:: wordTryCompareAndSwap in class MutatorContext

Parameters:: src - The object into which the new reference will be stored; slot - The address into which the new reference will be stored.; old - The old Word to be swapped out; value - The new Word; metaDataA - A value that assists the host VM in creating a store; metaDataB - A value that assists the host VM in creating a store; mode - The context in which the store occurred
