Class VejalCompiler

java.lang.Object
  aspoev.vejal.generator.VejalCompiler

public class VejalCompiler

extends java.lang.Object

This class creates a Java and Jasmine representation for Vejal types. Vejal types must be compiled prior to instantiation. However, purely procedural code does not need to be compiled, as long as it has no heap storage requirements.

Field Summary

protected static java.lang.String

directory

Constructor Summary

VejalCompiler()

Method Summary

protected static void	buildGeneratedObjects(java.lang.String dir) To be called after all dependent objects are generated from meta-data.
static void	buildODQL(java.lang.String dir, java.lang.String name) Register the ODQL file with the Jasmine ODQL interpreter.
static void	compileList(java.io.File listFile) Compile a list of Vejal files.
static java.lang.String	compileObjectSlice(TypeReferenceElement one, TypeReferenceElement two) Creates an object slice for the two types, i.e.
static ClassDeclarationElement	createSliceClass(TypeComparator comparator)
static void	main(java.lang.String[] args) Runs the compiler.
protected static ClassDeclarationElement	parseFile(java.io.File file)
protected static void	populateSchema(ClassDeclarationElement classDecl)
protected static void	printHelp() Prints compiler instructions.
static void	processClassDeclaration(ClassDeclarationElement classDecl) Compile the argument class declaration.
protected static boolean	processJavaObject(java.lang.String outputDirectory, java.lang.String files)
protected static void	registerClass(ClassDeclarationElement decl)
static java.lang.String	renderClass(ClassDeclarationElement decl) Renders the Vejal class declaration in Java.

directory

protected static java.lang.String directory

Constructor Detail

VejalCompiler

public VejalCompiler()

Method Detail

main

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

Runs the compiler.

buildGeneratedObjects

protected static void buildGeneratedObjects(java.lang.String dir)

To be called after all dependent objects are generated from meta-data.

buildODQL

public static void buildODQL(java.lang.String dir,
                             java.lang.String name)

Register the ODQL file with the Jasmine ODQL interpreter.

compileList

public static void compileList(java.io.File listFile)
                        throws java.lang.Exception

Compile a list of Vejal files.

Throws:

java.lang.Exception

compileObjectSlice

public static java.lang.String compileObjectSlice(TypeReferenceElement one,
                                                  TypeReferenceElement two)

Creates an object slice for the two types, i.e. to store the fields which are present in the second type but not in the first. A slice has no defining ClassDeclarationElement. At the moment, it is derived from the field differences between the two supplied types. If slice does not exist, generate it. If it does exist, exit.

createSliceClass

public static ClassDeclarationElement createSliceClass(TypeComparator comparator)

parseFile

protected static ClassDeclarationElement parseFile(java.io.File file)

populateSchema

protected static void populateSchema(ClassDeclarationElement classDecl)

processClassDeclaration

public static void processClassDeclaration(ClassDeclarationElement classDecl)

Compile the argument class declaration.

processJavaObject

protected static boolean processJavaObject(java.lang.String outputDirectory,
                                           java.lang.String files)

registerClass

protected static void registerClass(ClassDeclarationElement decl)

renderClass

public static java.lang.String renderClass(ClassDeclarationElement decl)

Renders the Vejal class declaration in Java. Returns the names of the Java classes it creates (class*es* because it might need to create the base class for all versions of the type.)

printHelp

protected static void printHelp()

Prints compiler instructions.
