MatrixPreprocessor visitor,
MatrixJep jep,
MatrixNodeFactory nf)
throws ParseException
SpecialPreProcessorIMatrixNodeI children[] = visitor.visitChildrenAsArray(node,null);The final step is to construct a node of the correct type. The MatrixNodeFactory argument has a number of methods to do this. For example
return (ASTMFunNode) nf.buildOperatorNode(node.getOperator(),children,rhsDim);Note how the dimension is specified.
preprocess in interface SpecialPreProcessorInode - the top node of the tree representing the function and its arguments.visitor - A reference to the preprocessing visitor.jep - A reference of the MatrixJep instance.nf - A reference to the node factory object.
ParseException - if some error occurs.
