Class ConstantValue

  • All Implemented Interfaces:
    Cloneable, Node

    public final class ConstantValue
    extends Attribute
    This class is derived from Attribute and represents a constant value, i.e., a default value for initializing a class field. This class is instantiated by the Attribute.readAttribute() method.

    • Constructor Detail

      • ConstantValue

        public ConstantValue​(ConstantValue c)
        Initialize from another object. Note that both objects use the same references (shallow copy). Use clone() for a physical copy.
      • ConstantValue

        public ConstantValue​(int name_index,
                             int length,
                             int constantValueIndex,
                             ConstantPool constant_pool)
        Parameters:
        name_index - Name index in constant pool
        length - Content length in bytes
        constantValueIndex - Index in constant pool
        constant_pool - Array of constants

      • accept

        public void accept​(Visitor v)
        Called by objects that are traversing the nodes of the tree implicitely defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.
        Specified by:
        accept in interface Node
        Specified by:
        accept in class Attribute
        Parameters:
        v - Visitor object
      • getConstantValueIndex

        public int getConstantValueIndex()
        Returns:
        Index in constant pool of constant value.
      • setConstantValueIndex

        public void setConstantValueIndex​(int constantValueIndex)
        Parameters:
        constantValueIndex - the index info the constant pool of this constant value
      • toString

        public String toString()
        Overrides:
        toString in class Attribute
        Returns:
        String representation of constant value.
