org.eigenbase.xom.MetaGenerator

public class MetaGenerator
extends java.lang.Object

MetaGenerator is a utility class which reads a XOM Meta Model description in XML and generates the corresponding .dtd and .java definition files. MetaGenerator is invoked during the build process to help generate files for the build.

Constructor Detail

MetaGenerator

public MetaGenerator(java.lang.String xmlFile,
                     boolean testMode)
              throws XOMException,
                     java.io.IOException

Construct a MetaGenerator from an XML file. The XML should meet the specifications of the XOM Meta Model.

Parameters:

xmlFile - a filename for the xml description of the model to be processed.

Throws:

XOMException

java.io.IOException

MetaGenerator

protected MetaGenerator(java.lang.String xmlFile,
                        boolean testMode,
                        java.lang.String className)
                 throws XOMException,
                        java.io.IOException

Throws:

XOMException

java.io.IOException

Method Detail

getTypeInfo

public org.eigenbase.xom.MetaGenerator.TypeInfo getTypeInfo(java.lang.String name,
                                                            boolean fail)
                                                     throws XOMException

Return the TypeInfo class associated with the given name.

Throws:

XOMException - if the type has not been defined

Post-condition:

fail == false || return != null

writeFiles
