List of extendMethod() Examples

Examples of extendMethod()

org.apache.tapestry.services.ClassTransformation.extendMethod()
Extends an existing method. The provided method body is inserted at the end of the existing method (i.e. {@link javassist.CtBehavior#insertAfter(java.lang.String)}). To access or change the return value, use the $_ pseudo variable.
The method may be declared in the class, or may be inherited from a super-class. For inherited methods, a method is added that first invokes the super implementation. Use {@link #addMethod(MethodSignature,String)} when it is necessary to control when thesuper-class method is invoked. @param signature the signature of the method to extend @param methodBody the body of code @throws IllegalArgumentException if the provided Javassist method body can not be compiled
org.apache.tapestry5.services.ClassTransformation.extendMethod()
Extends an existing method. The provided method body is inserted at the end of the existing method (i.e. {@link javassist.CtBehavior#insertAfter(java.lang.String)}). To access or change the return value, use the $_ pseudo variable.
The method may be declared in the class, or may be inherited from a super-class. For inherited methods, a method body is added that first invokes the super implementation. Use {@link #addMethod(TransformMethodSignature,String)} when it is necessary to control when the super-class methodis invoked.
The extended method is considered new. New methods are not scanned for {@linkplain #removeField(String)} removed}, {@linkplain #replaceReadAccess(String,String)} read replaced}, or{@linkplain #replaceWriteAccess(String,String) write replaced} fields. Generally that's what you want! @param methodSignature the signature of the method to extend @param methodBody the body of code @throws org.apache.tapestry5.internal.services.MethodCompileException if the provided Javassist method body can not be compiled @deprecated Use {@link TransformMethod#addAdvice(ComponentMethodAdvice)} instead. This method is non-functionalas of Tapestry 5.2.
