Interface AnnotationConfigurer<O,B extends AnnotationBuilder<O>>

Type Parameters:

O - The object being built by the AnnotationBuilder B

B - The AnnotationBuilder that builds objects of type O. This is also the AnnotationBuilder that is being configured.

void	init(B builder) Initialise the AnnotationBuilder.
boolean	isAssignable(AnnotationBuilder<O> builder)

Method Detail

init

void init(B builder)
          throws java.lang.Exception

Initialise the AnnotationBuilder. Here only shared state should be created and modified, but not properties on the AnnotationBuilder used for building the object. This ensures that the configure(AnnotationBuilder) method uses the correct shared objects when building.

Parameters:

builder - the builder

Throws:

java.lang.Exception - if error occurred

configure

void configure(B builder)
               throws java.lang.Exception

Configure the AnnotationBuilder by setting the necessary properties on the AnnotationBuilder.

Parameters:

builder - the builder

Throws:

java.lang.Exception - if error occurred

isAssignable

boolean isAssignable(AnnotationBuilder<O> builder)
