Description copied from interface: ClassInfo

Returns simple class name.

Specified by:

getClassname in interface ClassInfo

getSuperName

public java.lang.String getSuperName()

Description copied from interface: ClassInfo

Returns super class reference.

Specified by:

getSuperName in interface ClassInfo

getReference

public java.lang.String getReference()

Description copied from interface: ClassInfo

Returns class reference.

Specified by:

getReference in interface ClassInfo

getSuperClasses

Description copied from interface: ClassInfo

Returns array of super classes.

Specified by:

getSuperClasses in interface ClassInfo

getAnnotations

public AnnotationInfo[] getAnnotations()

Description copied from interface: ClassInfo

Returns annotation information or null if target class has no annotations.

Specified by:

getAnnotations in interface ClassInfo

visit

public void visit(int version,
                  int access,
                  java.lang.String name,
                  java.lang.String signature,
                  java.lang.String superName,
                  java.lang.String[] interfaces)

Description copied from class: ClassVisitor

Visits the header of the class.

Overrides:

visit in class ClassVisitor

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 (see Opcodes). This parameter also indicates if the class is deprecated Opcodes.ACC_DEPRECATED or a record Opcodes.ACC_RECORD.

name - the internal name of the class (see Type.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 Type.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 Type.getInternalName()). May be null.

visitAnnotation

public AnnotationVisitor visitAnnotation(java.lang.String desc,
                                         boolean visible)

Description copied from class: ClassVisitor

Visits an annotation of the class.

Overrides:

visitAnnotation in class 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.

visitMethod

public MethodVisitor visitMethod(int access,
                                 java.lang.String name,
                                 java.lang.String desc,
                                 java.lang.String signature,
                                 java.lang.String[] exceptions)

Stores method signature for target method.

Overrides:

exceptions - the internal names of the method's exception classes (see Type.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.
