类 Method_info

java.lang.Object

com.vladium.jcd.cls.Method_info

所有已实现的接口:

IAccessFlags, Cloneable

public final class Method_info
extends Object
implements Cloneable, IAccessFlags

Each class method, and each instance initialization method , is described by a variable-length method_info structure. The structure has the following format:

  method_info {
          u2 access_flags;
          u2 name_index;
          u2 descriptor_index;
          u2 attributes_count;
          attribute_info attributes[attributes_count];
  }
 

The value of the access_flags item is a mask of modifiers used to describe access permission to and properties of a method or instance initialization method.

The value of the name_index item must be a valid index into the constant pool table. The constant pool entry at that index must be a CONSTANT_Utf8_info structure representing either one of the special internal method names, either <init> or <clinit>, or a valid Java method name, stored as a simple (not fully qualified) name.

The value of the descriptor_index item must be a valid index into the constant pool table. The constant pool entry at that index must be a CONSTANT_Utf8_info structure representing a valid Java method descriptor.

Each value of the attributes table must be a variable-length attribute structure. A method can have any number of optional attributes associated with it. The only attributes defined by this specification for the attributes table of a method_info structure are the Code and Exceptions attributes. See CodeAttribute_info and ExceptionsAttribute_info.
