Constructor Detail

ClassFabImpl

public ClassFabImpl(CtClassSource source,
                    javassist.CtClass ctClass)

Method Detail

toString

public java.lang.String toString()

Returns a representation of the fabricated class, including inheritance, fields, constructors, methods and method bodies.

Overrides:

toString in class java.lang.Object

Since:

1.1

addField

public void addField(java.lang.String name,
                     java.lang.Class type)

Description copied from interface: ClassFab

Adds a new field with the given name and type. The field is added as a private field.

Specified by:

addField in interface ClassFab

containsMethod

public boolean containsMethod(MethodSignature ms)

Description copied from interface: ClassFab

Convenience method for checking whether the fabricated class already contains a method.

Specified by:

containsMethod in interface ClassFab

Parameters:

ms - the signature

Returns:

whether or not the fabricated class already contains the method

addMethod

public MethodFab addMethod(int modifiers,
                           MethodSignature ms,
                           java.lang.String body)

Description copied from interface: ClassFab

Adds a method. The method is a public instance method.

Specified by:

addMethod in interface ClassFab

Parameters:

modifiers - Modifiers for the method (see Modifier).

ms - defines the name, return type, parameters and exceptions thrown

body - The body of the method.

Returns:

a method fabricator, used to add catch handlers.

getMethodFab

public MethodFab getMethodFab(MethodSignature ms)

Description copied from interface: ClassFab

Returns a previous defined method so that it can be further enhanced (perhaps by adding additional catches, etc.).

Specified by:

getMethodFab in interface ClassFab

Parameters:

ms - the signature of the method previously added

Returns:

the MethodFab for that method, or null if the method has not been added yet

addConstructor

public void addConstructor(java.lang.Class[] parameterTypes,
                           java.lang.Class[] exceptions,
                           java.lang.String body)

Description copied from interface: ClassFab

Adds a constructor to the class. The constructor will be public.

Specified by:

addConstructor in interface ClassFab

Parameters:

parameterTypes - the type of each parameter, or null if the constructor takes no parameters.

exceptions - the type of each exception, or null if the constructor throws no exceptions.

body - The body of the constructor.
