Class TestASTReadWrite

java.lang.Object

uk.ac.sheffield.jast.test.TestASTReadWrite

public class TestASTReadWrite
extends java.lang.Object

Demonstrates the use of ASTReader and ASTWriter to perform bi-directional mapping between XML and Java objects. ASTReader is a pull-parser that builds a custom AST from user-defined Java classes, using XMLScanner to scan the input and Unmarshaller to map from XML to Java. ASTWriter writes the AST directly to file, using Marshaller to map from Java to XML. Both share a common Metadata repository.

Method Detail

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Demonstration program to unmarshal an XML file to a custom Java AST and marshal the AST back to XML again. ASTReader is instructed to map XML to Java classes from the package "uk.ac.sheffield.jast.test" and then reads the input file "Catalogue.xml" into an AST, which is rooted in the user-defined class "Catalogue". ASTWriter is instructed to use the same Metadata as ASTReader, then marshals the AST back to the file "Catalogue_Marshal.xml". The Metadata object is then examined to list its namespace-to-package mappings, its XML-to-Java name mappings and its metadata attribute mappings.

Parameters:

args - are ignored.

Throws:

java.lang.Exception - if an error occurs.
