All Implemented Interfaces:
ILogEntryProcessor, IStringLogEntryProcessor
public abstract class AStringLogEntryProcessor extends Object implements IStringLogEntryProcessor

Note: The use of this class is not always feasible in some situations, particularly due to the multiple inheritance limitations of Java.
