Method Detail

setAdditionalClassInformation

void setAdditionalClassInformation(ClassNode c)

getPluginDefaultGroovyMethods

Class[] getPluginDefaultGroovyMethods()

getPluginStaticGroovyMethods

Class[] getPluginStaticGroovyMethods()

configureAnnotationNodeFromDefinition

void configureAnnotationNodeFromDefinition(AnnotationNode definition,
                                           AnnotationNode root)

configureAnnotation

void configureAnnotation(AnnotationNode an)

configureClassNode

void configureClassNode(CompileUnit compileUnit,
                        ClassNode classNode)

invalidateCallSites

void invalidateCallSites()

getInvokeSpecialHandle

Object getInvokeSpecialHandle(Method m,
                              Object receiver)

Returns a handle with bound receiver to invokeSpecial the given method. This method will require at least Java 7, but since the source has to compile on older Java versions as well it is not marked to return a MethodHandle and uses Object instead

Returns:

null in case of jdk<7, otherwise a handle that takes the method call arguments for the invokespecial call

invokeHandle

Object invokeHandle(Object handle,
                    Object[] args)
             throws Throwable

Invokes a handle produced by #getInvokeSpecialdHandle

Parameters:

handle - the handle

args - arguments for the method call, can be empty but not null

Returns:

the result of the method call

Throws:

Throwable

getVersion

int getVersion()

Gives the version the plugin is made for

Returns:

7 for jdk7, 8 for jdk8, 9 for jdk9 or higher
