方法详细资料

visit

public void visit(int version,
 int access,
 String name,
 String signature,
 @Nullable
 String supername,
 String[] interfaces)

从类复制的说明: ClassVisitor

Visits the header of the class.

覆盖:

visit 在类中 ClassVisitor

参数:

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.

visitOuterClass

public void visitOuterClass(String owner,
 String name,
 String desc)

从类复制的说明: ClassVisitor

Visits the enclosing class of the class. This method must be called only if the class has an enclosing class.

覆盖:

visitOuterClass 在类中 ClassVisitor

参数:

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.

visitInnerClass

public void visitInnerClass(String name,
 @Nullable
 String outerName,
 String innerName,
 int access)

从类复制的说明: ClassVisitor

Visits information about an inner class. This inner class is not necessarily a member of the class being visited.

覆盖:

visitInnerClass 在类中 ClassVisitor

参数:

name - the internal name of an inner class (see Type.getInternalName()).

outerName - the internal name of the class to which the inner class belongs (see Type.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.

visitAnnotation

@Nullable
public AnnotationVisitor visitAnnotation(String descriptor,
 boolean visible)

从类复制的说明: ClassVisitor

Visits an annotation of the class.

覆盖:

visitAnnotation 在类中 ClassVisitor

参数:

descriptor - the class descriptor of the annotation class.

visible - true if the annotation is visible at runtime.

返回:

a visitor to visit the annotation values, or null if this visitor is not interested in visiting this annotation.

visitMethod

@Nullable
public MethodVisitor visitMethod(int access,
 String name,
 String descriptor,
 String signature,
 String[] exceptions)

从类复制的说明: 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.

覆盖:

visitMethod 在类中 ClassVisitor

参数:

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.

descriptor - 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 Type.getInternalName()). May be null.

返回:

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()

从类复制的说明: 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.

覆盖:

visitEnd 在类中 ClassVisitor

getMetadata

public SimpleAnnotationMetadata getMetadata()

getSource

private SimpleAnnotationMetadataReadingVisitor.Source getSource()

toClassName

private String toClassName(String name)

isBridge

private boolean isBridge(int access)

isInterface

private boolean isInterface(int access)
