Constructor Detail

MethodCodeAdapter

public MethodCodeAdapter(org.objectweb.asm.MethodVisitor mv,
                         String owner,
                         int access,
                         String name,
                         String desc,
                         Set<String> fields)

MethodCodeAdapter constructor.

Parameters:

mv - : MethodVisitor

owner - : Name of the class

access - : Method access

name - : Method name

desc - : Method descriptor

fields - : Contained fields

Method Detail

visitFieldInsn

public void visitFieldInsn(int opcode,
                           String owner,
                           String name,
                           String desc)

Visit an instruction modifying a method (GETFIELD/PUTFIELD).

Overrides:

visitFieldInsn in class org.objectweb.asm.MethodVisitor

Parameters:

opcode - : visited operation code

owner - : owner of the field

name - : name of the field

desc - : descriptor of the field

See Also:

MethodVisitor.visitFieldInsn(int, String, String, String)

visitAnnotation

public org.objectweb.asm.AnnotationVisitor visitAnnotation(String name,
                                                           boolean visible)

Visits an annotation. If the annotation is visible, the annotation is removed. In fact the annotation was already moved to the method replacing this one. If the annotation is not visible, this annotation is kept on this method.

Overrides:

visitAnnotation in class org.objectweb.asm.MethodVisitor

Parameters:

name - the name of the annotation

visible - the annotation visibility

Returns:

the null if the annotation is visible, otherwise returns MethodVisitor.visitAnnotation(String, boolean)

See Also:

MethodVisitor.visitAnnotation(java.lang.String, boolean)

visitParameterAnnotation

public org.objectweb.asm.AnnotationVisitor visitParameterAnnotation(int id,
                                                                    String name,
                                                                    boolean visible)

Visits a parameter annotation.

Overrides:

visitParameterAnnotation in class org.objectweb.asm.MethodVisitor

Parameters:

id - the parameter number.

name - the annotation name

visible - if te annotation visibility

Returns:

the null if the annotation is visible, otherwise returns MethodVisitor.visitAnnotation(String, boolean)

See Also:

MethodVisitor.visitParameterAnnotation(int, java.lang.String, boolean)
