Constructor Detail

FieldSetter

protected FieldSetter(FieldDescription fieldDescription)

Creates a new field setter.

Parameters:

fieldDescription - The field to write to.

Method Detail

isDefineMethod

public boolean isDefineMethod()

Description copied from interface: TypeWriter.MethodPool.Entry

Determines if this entry requires a method to be defined for a given instrumentation.

Specified by:

isDefineMethod in interface TypeWriter.MethodPool.Entry

Returns:

true if a method should be defined for a given instrumentation.

getByteCodeAppender

public ByteCodeAppender getByteCodeAppender()

Description copied from interface: TypeWriter.MethodPool.Entry

The byte code appender to be used for the instrumentation by this entry. Must not be called if TypeWriter.MethodPool.Entry.isDefineMethod() returns false.

Specified by:

getByteCodeAppender in interface TypeWriter.MethodPool.Entry

Returns:

The byte code appender that is responsible for the instrumentation of a method matched for this entry.

getAttributeAppender

public MethodAttributeAppender getAttributeAppender()

Description copied from interface: TypeWriter.MethodPool.Entry

The method attribute appender that is to be used for the instrumentation by this entry. Must not be called if TypeWriter.MethodPool.Entry.isDefineMethod() returns false.

Specified by:

getAttributeAppender in interface TypeWriter.MethodPool.Entry

Returns:

The method attribute appender that is responsible for the instrumentation of a method matched for this entry.

appendsCode

public boolean appendsCode()

Description copied from interface: ByteCodeAppender

Determines if this byte code appender offers an (possibly empty) implementation of a method.

Specified by:

appendsCode in interface ByteCodeAppender

Returns:

true if this byte code appender requires this method to be implemented or false if this appender describes an abstract method.

apply

public ByteCodeAppender.Size apply(org.objectweb.asm.MethodVisitor methodVisitor,
                                   Instrumentation.Context instrumentationContext,
                                   MethodDescription instrumentedMethod)

Description copied from interface: ByteCodeAppender

Applies this byte code appender to a type creation process.

Specified by:

apply in interface ByteCodeAppender

Parameters:

methodVisitor - The method visitor to which the byte code appender writes its code to.

instrumentationContext - The instrumentation context of the current type creation process.

instrumentedMethod - The method that is the target of the instrumentation.

Returns:

The required size for the applied byte code to run.

apply

public void apply(org.objectweb.asm.ClassVisitor classVisitor,
                  Instrumentation.Context instrumentationContext,
                  MethodDescription methodDescription)

Description copied from interface: TypeWriter.MethodPool.Entry

Writes the method that is represented by this entry to the provided class visitor.

Specified by:

apply in interface TypeWriter.MethodPool.Entry

Parameters:

classVisitor - The class visitor to which this entry is to be written to.

instrumentationContext - The instrumentation context to use for writing this method.

methodDescription - A description of the method that is to be written
