Constructor Detail

### Signature

    public Signature(Signature c)

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

### Signature

    public Signature(int name_index,
                     int length,
                     int signature_index,
                     ConstantPool constant_pool)

Parameters:
  `name_index` - Index in constant pool to CONSTANT_Utf8
  `length` - Content length in bytes
  `signature_index` - Index in constant pool to CONSTANT_Utf8
  `constant_pool` - Array of constants

Method Detail

### 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

### dump

    public final void dump(DataOutputStream file)
                    throws IOException

  Dump source file attribute to file stream in binary format.

  Overrides:
    `dump` in class `Attribute`
  Parameters:
    `file` - Output file stream
  Throws:
    `IOException`

### getSignatureIndex

    public final int getSignatureIndex()

  Returns:
    Index in constant pool of source file name.

### setSignatureIndex

    public final void setSignatureIndex(int signature_index)

  Parameters:
    `signature_index` - the index info the constant pool of this signature

### getSignature

    public final String getSignature()

  Returns:
    GJ signature.

### translate

    public static String translate(String s)

### isFormalParameterList

    public static final boolean isFormalParameterList(String s)

### isActualParameterList

    public static final boolean isActualParameterList(String s)

### toString

    public final String toString()

  Overrides:
    `toString` in class `Attribute`
  Returns:
    String representation

### copy

    public Attribute copy(ConstantPool _constant_pool)

  Specified by:
    `copy` in class `Attribute`
  Returns:
    deep copy of this attribute
