Examples of ptolemy.data.expr.ParseTreeTypeInference

ptolemy.data.expr.ParseTreeTypeInference
This class visits parse trees and infers a type for each node in the parse tree. This type is stored in the parse tree. @author Steve Neuendorffer @version $Id: ParseTreeTypeInference.java,v 1.65 2006/12/19 18:31:48 cxh Exp $ @since Ptolemy II 2.1 @Pt.ProposedRating Green (neuendor) @Pt.AcceptedRating Yellow (neuendor) @see ptolemy.data.expr.ASTPtRootNode
