Class ClassAdapter

java.lang.Object
org.objectweb.asm.ClassAdapter
All Implemented Interfaces:
ClassVisitor
Direct Known Subclasses:
CheckClassAdapter, RemappingClassAdapter, SerialVersionUIDAdder, StaticInitMerger

public class ClassAdapter extends Object implements ClassVisitor
An empty ClassVisitor that delegates to another ClassVisitor. This class can be used as a super class to quickly implement usefull class adapter classes, just by overriding the necessary methods.

    • visit

      public void visit(int version, int access, String name, String signature, String superName, String[] interfaces)
      Description copied from interface: ClassVisitor
      Visits the header of the class.
      Specified by:
      visit in interface ClassVisitor
      Parameters:
      version - the class version.
      access - the class's access flags (see Opcodes). This parameter also indicates if the class is deprecated.
      name - the internal name of the class (see 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 (see getInternalName). For interfaces, the super class is Object. May be null, but only for the Object class.
      interfaces - the internal names of the class's interfaces (see getInternalName). May be null.
    • visitSource

      public void visitSource(String source, String debug)
      Description copied from interface: ClassVisitor
      Visits the source of the class.
      Specified by:
      visitSource in interface ClassVisitor
      Parameters:
      source - the name of the source file from which the class was compiled. May be null.
      debug - additional debug information to compute the correspondance between source and compiled elements of the class. May be null.
    • visitOuterClass

      public void visitOuterClass(String owner, String name, String desc)
      Description copied from interface: ClassVisitor
      Visits the enclosing class of the class. This method must be called only if the class has an enclosing class.
      Specified by:
      visitOuterClass in interface ClassVisitor
      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.
    • visitAnnotation

      public AnnotationVisitor visitAnnotation(String desc, boolean visible)
      Description copied from interface: ClassVisitor
      Visits an annotation of the class.
      Specified by:
      visitAnnotation in interface ClassVisitor
      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.
    • visitAttribute

      public void visitAttribute(Attribute attr)
      Description copied from interface: ClassVisitor
      Visits a non standard attribute of the class.
      Specified by:
      visitAttribute in interface ClassVisitor
      Parameters:
      attr - an attribute.
    • visitInnerClass

      public void visitInnerClass(String name, String outerName, String innerName, int access)
      Description copied from interface: ClassVisitor
      Visits information about an inner class. This inner class is not necessarily a member of the class being visited.
      Specified by:
      visitInnerClass in interface ClassVisitor
      Parameters:
      name - the internal name of an inner class (see getInternalName).
      outerName - the internal name of the class to which the inner class belongs (see 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.
    • visitField

      public FieldVisitor visitField(int access, String name, String desc, String signature, Object value)
      Description copied from interface: ClassVisitor
      Visits a field of the class.
      Specified by:
      visitField in interface ClassVisitor
      Parameters:
      access - the field's access flags (see Opcodes). This parameter also indicates if the field is synthetic and/or deprecated.
      name - the field's name.
      desc - the field's descriptor (see Type).
      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 an Integer, a Float, a Long, a Double or a String (for int, float, long or String 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.
    • visitMethod

      public MethodVisitor visitMethod(int access, String name, String desc, String signature, String[] exceptions)
      Description copied from interface: ClassVisitor
      Visits a method of the class. This method must return a new MethodVisitor instance (or null) each time it is called, i.e., it should not return a previously returned visitor.
      Specified by:
      visitMethod in interface ClassVisitor
      Parameters:
      access - the method's access flags (see Opcodes). This parameter also indicates if the method is synthetic and/or deprecated.
      name - the method's name.
      desc - the method's descriptor (see Type).
      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 (see 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.
    • visitEnd

      public void visitEnd()
      Description copied from interface: ClassVisitor
      Visits the end of the class. This method, which is the last one to be called, is used to inform the visitor that all the fields and methods of the class have been visited.
      Specified by:
      visitEnd in interface ClassVisitor
