StaticInitMerger

public StaticInitMerger(String prefix,
 ClassVisitor classVisitor)

Constructs a new StaticInitMerger.

参数:

prefix - the prefix to use to rename the existing <clinit> methods.

classVisitor - the class visitor to which this visitor must delegate method calls. May be null.

方法详细资料

visit

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

从类复制的说明: ClassVisitor

Visits the header of the class.

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.

visitMethod

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.
