Constructor Detail

WrapperQueryProcessor

public WrapperQueryProcessor()

Create an instance of the Query Processor. More than one instance can be created without possibility of inteference with any other instance of the query processor.

Method Detail

process

public void process(ASG g,
                    Schema s,
