 package com.sleepycat.asm;

A visitor to visit a Java annotation. The methods of this class must be called in the following order: ( visit | visitEnum | visitAnnotation | visitArray )* visitEnd.

Author(s):
Eric Bruneton
Eugene Kuleshov
 
 public abstract class AnnotationVisitor {

    
The ASM API version implemented by this visitor. The value of this field must be one of Opcodes.ASM4.
 
     protected final int api;

    
The annotation visitor to which this visitor must delegate method calls. May be null.
 
     protected AnnotationVisitor av;

    
Constructs a new AnnotationVisitor.

Parameters:
api the ASM API version implemented by this visitor. Must be one of Opcodes.ASM4.
 
     public AnnotationVisitor(final int api) {
         this(apinull);
     }

    
Constructs a new AnnotationVisitor.

Parameters:
api the ASM API version implemented by this visitor. Must be one of Opcodes.ASM4.
av the annotation visitor to which this visitor must delegate method calls. May be null.
 
     public AnnotationVisitor(final int apifinal AnnotationVisitor av) {
         /*if (api != Opcodes.ASM4) {
             throw new IllegalArgumentException();
         }*/
         this. = api;
         this. = av;
     }

    
Visits a primitive value of the annotation.

Parameters:
name the value name.
value the actual value, whose type must be java.lang.Byte, java.lang.Boolean, java.lang.Character, java.lang.Short, java.lang.Integer , java.lang.Long, java.lang.Float, java.lang.Double, java.lang.String or Type or OBJECT or ARRAY sort. This value can also be an array of byte, boolean, short, char, int, long, float or double values (this is equivalent to using visitArray and visiting each array element in turn, but is more convenient).
 
     public void visit(String nameObject value) {
         if ( != null) {
             .visit(namevalue);
         }
     }

    
Visits an enumeration value of the annotation.

Parameters:
name the value name.
desc the class descriptor of the enumeration class.
value the actual enumeration value.
    public void visitEnum(String nameString descString value) {
        if ( != null) {
            .visitEnum(namedescvalue);
        }
    }

    
Visits a nested annotation value of the annotation.

Parameters:
name the value name.
desc the class descriptor of the nested annotation class.
Returns:
a visitor to visit the actual nested annotation value, or null if this visitor is not interested in visiting this nested annotation. The nested annotation value must be fully visited before calling other methods on this annotation visitor.
    public AnnotationVisitor visitAnnotation(String nameString desc) {
        if ( != null) {
            return .visitAnnotation(namedesc);
        }
        return null;
    }

    
Visits an array value of the annotation. Note that arrays of primitive types (such as byte, boolean, short, char, int, long, float or double) can be passed as value to visit. This is what ClassReader does.

Parameters:
name the value name.
Returns:
a visitor to visit the actual array value elements, or null if this visitor is not interested in visiting these values. The 'name' parameters passed to the methods of this visitor are ignored. All the array values must be visited before calling other methods on this annotation visitor.
    public AnnotationVisitor visitArray(String name) {
        if ( != null) {
            return .visitArray(name);
        }
        return null;
    }

    
Visits the end of the annotation.
    public void visitEnd() {
        if ( != null) {
            .visitEnd();
        }
    }
