MatrixValueI	evaluate(MatrixNodeI node, MatrixEvaluator visitor, MatrixJep jep) Returns the result of evaluating this node and the tree below.

Method Detail

evaluate

MatrixValueI evaluate(MatrixNodeI node,
                      MatrixEvaluator visitor,
                      MatrixJep jep)
               throws ParseException

Returns the result of evaluating this node and the tree below. This method has the responsibility for evaluating the children of the node and it should generally call

 MatrixValueI val = (MatrixValueI) node.jjtGetChild(i).jjtAccept(visitor,null); 
 

for each child.

The final results should be copied into the mvalue field of the node using

 MatrixValueI mvalue = node.getMValue();
 mvalue.setEles(res);
 return mvalue;
 

Parameters:

node - The top node.

visitor - The parser visitor

jep - The current MatrixJep instance.

Returns:

Value after evaluation.

Throws:

ParseException
