Class Synthetic

  • All Implemented Interfaces:
    java.lang.Cloneable, Node

    public final class Synthetic
    extends Attribute
    This class is derived from Attribute and declares this class as 'synthetic', i.e., it needs special handling. The JVM specification states "A class member that does not appear in the source code must be marked using a Synthetic attribute." It may appear in the ClassFile attribute table, a field_info table or a method_info table. This class is intended to be instantiated from the Attribute.readAttribute() method.

      • Synthetic

        public Synthetic​(Synthetic c)
        Initialize from another object. Note that both objects use the same references (shallow copy). Use copy() for a physical copy.
        Parameters:
        c - Source to copy.

      • accept

        public void accept​(Visitor v)
        Called by objects that are traversing the nodes of the tree implicitly defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.

        accept in interface Node
        Specified by:
        accept in class Attribute
        Parameters:
        v - Visitor object
      • copy

        public Attribute copy​(ConstantPool constantPool)
        Specified by:
        copy in class Attribute
        Parameters:
        constantPool - constant pool to save.
        Returns:
        deep copy of this attribute
      • dump

        public void dump​(java.io.DataOutputStream file)
                  throws java.io.IOException
        Dump source file attribute to file stream in binary format.
        Overrides:
