public class ConstructorCodeAdapter
extends org.objectweb.asm.commons.GeneratorAdapter
implements org.objectweb.asm.Opcodes

Constructor Adapter. This class adds an instance manager argument (so switch variable index). Moreover, it adapts field accesses to delegate accesses to the instance manager if needed.

Constructor Detail

ConstructorCodeAdapter

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

PropertyCodeAdapter constructor. A new FiledCodeAdapter should be create for each method visit.

Parameters:

mv - the MethodVisitor

owner - the name of the class

fields - the list of contained fields

finalFields - the list of contained final fields

access - the constructor access

name - the name

desc - the constructor descriptor

Method Detail

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 parameter,
                                                                    String desc,
                                                                    boolean visible)

Visits a parameter annotation. Parameter annotations are moved to replacing constructor except they are injection annotations(-@Property and -@Requires). Because injection annotations shouldn't be copied to generated one in case of re-manipulation, since this is caused to wrong type resolution of injected parameters.

Overrides:

visitParameterAnnotation in class org.objectweb.asm.MethodVisitor

Parameters:

parameter - parameter index

desc - annotation description(annotation name)

visible - is parameter annotation visible

Returns:

@AnnotationVisitor

visitFieldInsn

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

Adapts field accesses. If the field is owned by the visited class:

• GETFIELD are changed to a __getX invocation.
• SETFIELD are changed to a __setX invocation.

Overrides:

visitFieldInsn in class org.objectweb.asm.MethodVisitor

Parameters:

opcode - the visited operation code

owner - the owner of the field

name - the name of the field

desc - the descriptor of the field

See Also:

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

visitMethodInsn

public void visitMethodInsn(int opcode,
                            String owner,
                            String name,
                            String desc,
                            boolean itf)

Visits a method invocation instruction. After the super constructor invocation, insert the _setComponentManager invocation. Otherwise, the method invocation doesn't change

Overrides:

visitMethodInsn in class org.objectweb.asm.MethodVisitor

Parameters:

opcode - the opcode

owner - the class owning the invoked method

name - the method name

desc - the method descriptor

itf - if the method's owner class is an interface

See Also:

MethodVisitor.visitMethodInsn(int, java.lang.String, java.lang.String, java.lang.String)

visitVarInsn

public void visitVarInsn(int opcode,
                         int var)

Visits a variable instruction. This method increments the variable index if it is not this (i.e. 0). This increment is due to the instance manager parameter added in the method signature.

Overrides:

visitVarInsn in class org.objectweb.asm.commons.LocalVariablesSorter

Parameters:

opcode - the opcode

var - the variable index

See Also:

LocalVariablesSorter.visitVarInsn(int, int)

visitIincInsn

public void visitIincInsn(int var,
                          int increment)

Visits an increment instruction. This method increments the variable index if it is not this (i.e. 0). This increment is due to the instance manager parameter added in the method signature.

Overrides:

visitIincInsn in class org.objectweb.asm.commons.LocalVariablesSorter

Parameters:

var - the variable index

increment - the increment

See Also:

LocalVariablesSorter.visitIincInsn(int, int)

visitLocalVariable

public void visitLocalVariable(String name,
                               String desc,
                               String signature,
                               org.objectweb.asm.Label start,
                               org.objectweb.asm.Label end,
                               int index)

Visits a local variable. Adds _manager and increment others variable indexes. This variable has the same scope than this and has the 1 index.

Overrides:

visitLocalVariable in class org.objectweb.asm.commons.LocalVariablesSorter

Parameters:

name - the variable name

desc - the variable descriptor

signature - the variable signature

start - the beginning label

end - the ending label

index - the variable index

See Also:

LocalVariablesSorter.visitLocalVariable(java.lang.String, java.lang.String, java.lang.String, org.objectweb.asm.Label, org.objectweb.asm.Label, int)

visitMaxs

public void visitMaxs(int maxStack,
                      int maxLocals)

Visit max method. The stack size is incremented of 1. The local variable count is incremented of 2.

Overrides:

visitMaxs in class org.objectweb.asm.commons.LocalVariablesSorter

Parameters:

maxStack - the stack size.

maxLocals - the local variable count.
