Method Details

addException

public MethodCreator addException(String exception)

Description copied from interface: MethodCreator

Adds an exception to the method signature

Specified by:

addException in interface MethodCreator

Parameters:

exception - The exception

Returns:

This creator

getExceptions

public List<String> getExceptions()

Specified by:

getExceptions in interface MethodCreator

Returns:

The exceptions thrown by this method

getMethodDescriptor

public MethodDescriptor getMethodDescriptor()

Specified by:

getMethodDescriptor in interface MethodCreator

Returns:

The method descriptor

getParameterAnnotations

public AnnotatedElement getParameterAnnotations(int param)

Specified by:

getParameterAnnotations in interface MethodCreator

setParameterNames

public void setParameterNames(String[] parameterNames)

Description copied from interface: MethodCreator

Sets names of all this method's parameters. The length of parameterNames must be equal to the number of this method's parameters. Removes previously set parameter names if parameterNames is null.

It is required to set all parameter names in one go, because parameter names are stored in bytecode as a simple sequence, without positions.

When generating a method with mandated or synthetic parameters (such as an inner class constructor), remember that these parameters must have names too.

Specified by:

setParameterNames in interface MethodCreator

Parameters:

parameterNames - names of all parameters of this method

getModifiers

public int getModifiers()

Specified by:

getModifiers in interface MemberCreator<MethodCreator>

setModifiers

public MethodCreator setModifiers(int mods)

Specified by:

setModifiers in interface MemberCreator<MethodCreator>

write

public void write(org.objectweb.asm.ClassVisitor file)

Specified by:

write in interface MemberCreator<MethodCreator>

resolve

ResultHandle resolve(ResultHandle handle,
 BytecodeCreator creator)

Overrides:

resolve in class BytecodeCreatorImpl

resolve

ResultHandle[] resolve(BytecodeCreator owner,
 ResultHandle... handles)

Overrides:

resolve in class BytecodeCreatorImpl

toString

public String toString()

Overrides:

toString in class Object

addAnnotation

public AnnotationCreator addAnnotation(String annotationType,
 RetentionPolicy retentionPolicy)

Specified by:

addAnnotation in interface AnnotatedElement

getDeclaringClassName

String getDeclaringClassName()

getClassOutput

ClassOutput getClassOutput()

getClassCreator

ClassCreator getClassCreator()

addFunctionBody

FunctionCreatorImpl addFunctionBody(ResultHandle instance,
 ClassCreator cc,
 MethodCreatorImpl mc,
 BytecodeCreatorImpl owner)

getSignature

public String getSignature()

Specified by:

getSignature in interface SignatureElement<MethodCreator>

setSignature

public MethodCreator setSignature(String signature)

Description copied from interface: SignatureElement

Use the convenient SignatureBuilder to build signatures for classes, methods and fields.

Specified by:

setSignature in interface SignatureElement<MethodCreator>

Parameters:

signature - The generic signature as defined in JVMS 17, chapter "4.7.9.1. Signatures"

Returns:

the element
