@Override

Overrides org.objectweb.asm.ClassVisitor.visitInnerClass.

Doc from org.objectweb.asm.ClassVisitor.visitInnerClass.

Visits information about an inner class. This inner class is not necessarily a member of the class being visited. More precisely, every class or interface C which is referenced by this class and which is not a package member must be visited with this method. This class must reference its nested class or interface members, and its enclosing class, if any. See the JVMS 4.7.6 section for more details.

Parameters

name:String

the internal name of C (see Type#getInternalName()).

outerName:String

the internal name of the class or interface C is a member of (see Type#getInternalName()). Must be null if C is not the member of a class or interface (e.g. for local or anonymous classes).

innerName:String

the (simple) name of C. Must be null for anonymous inner classes.

access:int

@Override

Overrides org.objectweb.asm.ClassVisitor.visitMethod.

Doc from org.objectweb.asm.ClassVisitor.visitMethod.

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.

Parameters

access:int

the method's access flags (see Opcodes). This parameter also indicates if the method is synthetic and/or deprecated.

name:String

the method's name.

descriptor:String

the method's descriptor (see Type).

signature:String

the method's signature. May be null if the method parameters, return type and exceptions do not use generic types.

exceptions:String[]

the internal names of the method's exception classes (see Type#getInternalName()). May be null.

Returns:MethodVisitor

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.

Annotations

@Override

Overrides org.objectweb.asm.ClassVisitor.visitModule.

Doc from org.objectweb.asm.ClassVisitor.visitModule.

Visit the module corresponding to the class.

Parameters

name:String

the fully qualified name (using dots) of the module.

access:int

the module access flags, among ACC_OPEN, ACC_SYNTHETIC and ACC_MANDATED.

version:String

Annotations

@Override

Overrides org.objectweb.asm.ClassVisitor.visitNestHost.

Doc from org.objectweb.asm.ClassVisitor.visitNestHost.

Visits the nest host class of the class. A nest is a set of classes of the same package that share access to their private members. One of these classes, called the host, lists the other members of the nest, which in turn should link to the host of their nest. This method must be called only once and only if the visited class is a non-host member of a nest. A class is implicitly its own nest, so it's invalid to call this method with the visited class name as argument.

Parameters

nestHost:String

the internal name of the host class of the nest (see Type#getInternalName()).

Annotations

@Override

Overrides org.objectweb.asm.ClassVisitor.visitNestMember.

Doc from org.objectweb.asm.ClassVisitor.visitNestMember.

Visits a member of the nest. A nest is a set of classes of the same package that share access to their private members. One of these classes, called the host, lists the other members of the nest, which in turn should link to the host of their nest. This method must be called only if the visited class is the host of a nest. A nest host is implicitly a member of its own nest, so it's invalid to call this method with the visited class name as argument.

Parameters

nestMember:String

the internal name of a nest member (see Type#getInternalName()).

Annotations

@Override

Overrides org.objectweb.asm.ClassVisitor.visitOuterClass.

Doc from org.objectweb.asm.ClassVisitor.visitOuterClass.

Visits the enclosing class of the class. This method must be called only if this class is a local or anonymous class. See the JVMS 4.7.7 section for more details.

Parameters

owner:String

internal name of the enclosing class of the class (see Type#getInternalName()).

name:String

the name of the method that contains the class, or null if the class is not enclosed in a method or constructor of its enclosing class (e.g. if it is enclosed in an instance initializer, static initializer, instance variable initializer, or class variable initializer).

descriptor:String

the descriptor of the method that contains the class, or null if the class is not enclosed in a method or constructor of its enclosing class (e.g. if it is enclosed in an instance initializer, static initializer, instance variable initializer, or class variable initializer).

Annotations
