public interface InterceptorCodeGenerator

Processor-path plugin extension point for direct interceptor code generation.

Method Summary

Modifier and Type	Method	Description
void	emitAfter(InterceptedMethodModel method, InterceptorBindingModel binding, LifecycleCodeEmitter emitter)	Emit code that runs after a successful target method invocation.
void	emitAfterException(InterceptedMethodModel method, InterceptorBindingModel binding, LifecycleCodeEmitter emitter)	Emit code that runs when the target method invocation or an inner interceptor fails.
void	emitBefore(InterceptedMethodModel method, InterceptorBindingModel binding, LifecycleCodeEmitter emitter)	Emit code that runs before the target method invocation.
boolean	supports(InterceptorBindingModel binding)	Return true if this generator claims the effective interceptor binding.

Method Details

supports

boolean supports(@Nonnull InterceptorBindingModel binding)

Return true if this generator claims the effective interceptor binding.

Parameters:

binding - the effective interceptor binding.

Returns:

true if this generator claims the effective interceptor binding.

emitBefore
