getWorkData
public WorkData getWorkData()
Returns working data.

visit
public void visit(int version, int access, java.lang.String name, java.lang.String signature, java.lang.String superName, java.lang.String[] interfaces)
Creates destination subclass header from current target class. Destination name is created from targets by adding a suffix and, optionally, a number. Destination extends the target.- Overrides:
visit
in classClassVisitor
- Parameters:
version
- the class version. The minor version is stored in the 16 most significant bits, and the major version in the 16 least significant bits.access
- the class's access flags (seeOpcodes
). This parameter also indicates if the class is deprecatedOpcodes.ACC_DEPRECATED
or a recordOpcodes.ACC_RECORD
.name
- the internal name of the class (seeType.getInternalName()
).signature
- the signature of this class. May be null if the class is not a generic one, and does not extend or implement generic classes or interfaces.superName
- the internal of name of the super class (seeType.getInternalName()
). For interfaces, the super class isObject
. May be null, but only for theObject
class.interfaces
- the internal names of the class's interfaces (seeType.getInternalName()
). May be null.
-
visitMethod
public MethodVisitor visitMethod(int access, java.lang.String name, java.lang.String desc, java.lang.String signature, java.lang.String[] exceptions)
Creates proxified methods and constructors. Destination proxy will have all constructors as a target class, usingProxettaCtorBuilder
. Static initializers are removed, since they will be execute in target anyway. For each method,ProxettaMethodBuilder
determines if method matches pointcut. If so, method will be proxified.- Overrides:
visitMethod
in classClassVisitor
- Parameters:
access
- the method's access flags (seeOpcodes
). This parameter also indicates if the method is synthetic and/or deprecated.name
- the method's name.desc
- the method's descriptor (seeType
).signature
- the method's signature. May be null if the method parameters, return type and exceptions do not use generic types.exceptions
- the internal names of the method's exception classes (seeType.getInternalName()
). May be null.- Returns:
- an object to visit the byte code of the method, or null if this class visitor is not interested in visiting the code of this method.
-
visitField
public FieldVisitor visitField(int access, java.lang.String name, java.lang.String desc, java.lang.String signature, java.lang.Object value)
Ignores fields. Fields are not copied to the destination.- Overrides:
visitField
in classClassVisitor
- Parameters:
access
- the field's access flags (seeOpcodes
). This parameter also indicates if the field is synthetic and/or deprecated.name
- the field's name.desc
- the field's descriptor (seeType
).signature
- the field's signature. May be null if the field's type does not use generic types.value
- the field's initial value. This parameter, which may be null if the field does not have an initial value, must be anInteger
, aFloat
, aLong
, aDouble
or aString
(forint
,float
,long
orString
fields respectively). This parameter is only used for static fields. Its value is ignored for non static fields, which must be initialized through bytecode instructions in constructors or methods.- Returns:
- a visitor to visit field annotations and attributes, or null if this class visitor is not interested in visiting these annotations and attributes.
-
visitAnnotation
public AnnotationVisitor visitAnnotation(java.lang.String desc, boolean visible)
Copies all destination type annotations to the target.- Overrides:
visitAnnotation
in classClassVisitor
- Parameters:
desc
- the class descriptor of the annotation class.visible
- true if the annotation is visible at runtime.- Returns:
- a visitor to visit the annotation values, or null if this visitor is not interested in visiting this annotation.
-
visitEnd
public void visitEnd()
Finalizes creation of destination proxy class.- Overrides:
visitEnd
in classClassVisitor
-
makeStaticInitBlock
protected void makeStaticInitBlock()
Creates static initialization block that simply calls all advice static init methods in correct order.
-
makeProxyConstructor
protected void makeProxyConstructor()
Creates init method that simply calls all advice constructor methods in correct order. This created init method is called from each destination's constructor.
-
processSuperMethods
protected void processSuperMethods()
Checks for all public super methods that are not overridden.
-
visitSource
public void visitSource(java.lang.String source, java.lang.String debug)
Visits the source of the class (not used).- Overrides:
visitSource
in classClassVisitor
- Parameters:
source
- the name of the source file from which the class was compiled. May be null.debug
- additional debug information to compute the correspondence between source and compiled elements of the class. May be null.
-
visitOuterClass
public void visitOuterClass(java.lang.String owner, java.lang.String name, java.lang.String desc)
Visits the enclosing class of the class (not used).- Overrides:
visitOuterClass
in classClassVisitor
- Parameters:
owner
- internal name of the enclosing class of the class.name
- the name of the method that contains the class, or null if the class is not enclosed in a method of its enclosing class.desc
- the descriptor of the method that contains the class, or null if the class is not enclosed in a method of its enclosing class.
-
visitAttribute
public void visitAttribute(Attribute attr)
Visits a non standard attribute of the class (not used).- Overrides:
visitAttribute
in classClassVisitor
- Parameters:
attr
- an attribute.
-
visitInnerClass
public void visitInnerClass(java.lang.String name, java.lang.String outerName, java.lang.String innerName, int access)
Visits information about an inner class (not used).- Overrides:
visitInnerClass
in classClassVisitor
- Parameters:
name
- the internal name of an inner class (seeType.getInternalName()
).outerName
- the internal name of the class to which the inner class belongs (seeType.getInternalName()
). May be null for not member classes.innerName
- the (simple) name of the inner class inside its enclosing class. May be null for anonymous inner classes.access
- the access flags of the inner class as originally declared in the enclosing class.
-
