Constructors Summary
FieldOrMethod()

protected FieldOrMethod(FieldOrMethod c)
Initialize from another object. Note that both objects use the same references (shallow copy). Use clone() for a physical copy.

    this(c.getAccessFlags(), c.getNameIndex(), c.getSignatureIndex(),
	 c.getAttributes(), c.getConstantPool());
  
protected FieldOrMethod(DataInputStream file, ConstantPool constant_pool)
Construct object from file stream.

param
file Input stream
throws
IOException
throws
ClassFormatException

    this(file.readUnsignedShort(), file.readUnsignedShort(),
	 file.readUnsignedShort(), null, constant_pool);

    attributes_count = file.readUnsignedShort();
    attributes       = new Attribute[attributes_count];
    for(int i=0; i < attributes_count; i++)
      attributes[i] = Attribute.readAttribute(file, constant_pool);
  
protected FieldOrMethod(int access_flags, int name_index, int signature_index, Attribute[] attributes, ConstantPool constant_pool)

param
access_flags Access rights of method
param
name_index Points to field name in constant pool
param
signature_index Points to encoded signature
param
attributes Collection of attributes
param
constant_pool Array of constants
