Constructor Detail

ExpressionDeParser

public ExpressionDeParser()

ExpressionDeParser

public ExpressionDeParser(SelectVisitor selectVisitor,
                          java.lang.StringBuffer buffer)

Parameters:

selectVisitor - a SelectVisitor to de-parse SubSelects. It has to share the same
StringBuffer as this object in order to work, as:

 
 StringBuffer myBuf = new StringBuffer();
 MySelectDeparser selectDeparser = new  MySelectDeparser();
 selectDeparser.setBuffer(myBuf);
 ExpressionDeParser expressionDeParser = new ExpressionDeParser(selectDeparser, myBuf);
 
 

buffer - the buffer that will be filled with the expression
