public class GenerateProxyClass

extends Object

implements JevaParserConstants

generateClass(InterpretedClass) generates the proxy class for an interpreted object from the InterpretedClass. The proxy class has the correct signature for the class, but calls the interpreted methods and constructors for all its operations.

Note: if class calls super.methodName(..), then we must add some private methods to implement the super call. The private methods are of the form private TYPE $super$methodName(arg1..){ return super.methodName(arg1..);}

Method Summary

static void	decache() decache classes that have been generated so far this session
static String	defaultValueSource(Class storeType) generate source code for the default value for a type, e.g., "false" for boolean, "0" for numbers, "null" for non-primitive types
static String	defaultValueSource(IClass storeType) generate source code for the default value for a type, e.g., "false" for boolean, "0" for numbers, "null" for non-primitive types
static Class	generateClass(InterpretedClass iClass) Generate proxy class for iClass.
static Set	generateCompileSet(InterpretedClass iClass) From a verified InterpretedClass C for which a proxy class is to be generated, generate a list of interpreted classes which must also have their proxy classes written out along with C in order for C's proxy class to be compiled.
static String	generateSource(InterpretedClass iClass) generate compilation unit for a proxy class for iClass
static String	unwrapExpressionIfPrimitive(String expr, Class type) generate source code to unwrap a value if it is primitive, e.g., ("i", int.class)-->"((Integer)i).intValue()", ("i", Object.class)-->"i"
static String	wrapExpressionIfPrimitive(String expr, Class type) generate source code to wrap a value if it is primitive, e.g., ("i", int.class) --> "new Integer(i)", ("i", Object.class) --> "i"

public GenerateProxyClass()

Method Detail

generateClass

public static Class generateClass(InterpretedClass iClass)

Generate proxy class for iClass.

decache

public static void decache()

decache classes that have been generated so far this session

generateCompileSet

public static Set generateCompileSet(InterpretedClass iClass)

From a verified InterpretedClass C for which a proxy class is to be generated, generate a list of interpreted classes which must also have their proxy classes written out along with C in order for C's proxy class to be compiled. This includes all classes referred to by C's proxy class, which is the same as all classes referred to in C's signature, including superclass, interfaces, method, constructor, and fields type signatures, and throws declarations. It does not include types used within method/constructor bodies or static/object/field initializers, as the generated proxy classes use no additional interpreted types in their body.

generateSource

public static String generateSource(InterpretedClass iClass)

generate compilation unit for a proxy class for iClass

wrapExpressionIfPrimitive

public static String wrapExpressionIfPrimitive(String expr,
                                               Class type)

generate source code to wrap a value if it is primitive, e.g., ("i", int.class) --> "new Integer(i)", ("i", Object.class) --> "i"

wrapExpressionIfPrimitive

public static String wrapExpressionIfPrimitive(String expr,
                                               IClass type)

unwrapExpressionIfPrimitive

public static String unwrapExpressionIfPrimitive(String expr,
                                                 Class type)

generate source code to unwrap a value if it is primitive, e.g., ("i", int.class)-->"((Integer)i).intValue()", ("i", Object.class)-->"i"

defaultValueSource

public static final String defaultValueSource(Class storeType)

generate source code for the default value for a type, e.g., "false" for boolean, "0" for numbers, "null" for non-primitive types

defaultValueSource

public static final String defaultValueSource(IClass storeType)

generate source code for the default value for a type, e.g., "false" for boolean, "0" for numbers, "null" for non-primitive types
