Constructor Detail

ReadWriteFieldMarker

public ReadWriteFieldMarker(MutableBoolean repeatTrigger)

Creates a new ReadWriteFieldMarker that marks fields that are read and fields that are written.

Parameters:

repeatTrigger - a mutable boolean flag that is set whenever a field gets a mark that it didn't have before.

ReadWriteFieldMarker

public ReadWriteFieldMarker(MutableBoolean repeatTrigger,
                            boolean markReading,
                            boolean markWriting)

Creates a new ReadWriteFieldMarker that marks fields that are read and fields that are written, as specified.

Parameters:

repeatTrigger - a mutable boolean flag that is set whenever a field gets a mark that it didn't have before.

markReading - specifies whether fields may be marked as read.

markWriting - specifies whether fields may be marked as written.
