updateInstructionThreadID

public void updateInstructionThreadID(String pattern,
                                      String replace)

All instructions that have thread-specific filenames or names encoded in it should overwrite this method in order to update (1) the in-memory instruction and (2) the instruction string

Parameters:

pattern - ?

replace - ?

preprocessInstruction

public Instruction preprocessInstruction(org.apache.sysml.runtime.controlprogram.context.ExecutionContext ec)

This method should be used for any setup before executing this instruction. Overwriting methods should first call the super method and subsequently do their custom setup.

Parameters:

ec - execution context

Returns:

instruction

processInstruction

public abstract void processInstruction(org.apache.sysml.runtime.controlprogram.context.ExecutionContext ec)

This method should be used to execute the instruction.

Parameters:

ec - execution context

postprocessInstruction

public void postprocessInstruction(org.apache.sysml.runtime.controlprogram.context.ExecutionContext ec)

This method should be used for any tear down after executing this instruction. Overwriting methods should first do their custom tear down and subsequently call the super method.

Parameters:

ec - execution context
