- ## Constructor Details

  - ### FieldOrMethod

    protected FieldOrMethod(DataInput file, ConstantPool constantPool) throws IOException
    Constructs object from file stream.
    Parameters:
      `file` - Input stream
    Throws:
      `IOException` - if an I/O error occurs.

  - ### FieldOrMethod

    @Deprecated protected FieldOrMethod(DataInputStream file, ConstantPool constantPool) throws IOException
    Deprecated.
    (6.0) Use `FieldOrMethod(java.io.DataInput, ConstantPool)` instead.
    Constructs object from file stream.
    Parameters:
      `file` - Input stream
    Throws:
      `IOException` - if an I/O error occurs.

  - ### 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.
    Parameters:
      `c` - Source to copy.

  - ### FieldOrMethod

    protected FieldOrMethod(int accessFlags, int nameIndex, int signatureIndex, Attribute[] attributes, ConstantPool constantPool)
    Parameters:
      `accessFlags` - Access rights of method
      `nameIndex` - Points to field name in constant pool
      `signatureIndex` - Points to encoded signature
      `attributes` - Collection of attributes
      `constantPool` - Array of constants

- ## Method Details

  - ### copy_

    protected FieldOrMethod copy_(ConstantPool constantPool)
    Returns:
      deep copy of this field

  - ### dump

    public final void dump(DataOutputStream file) throws IOException
    Dump object to file stream on binary format.
    Parameters:
      `file` - Output file stream
    Throws:
      `IOException` - if an I/O error occurs.

  - ### getAnnotationEntries

    public AnnotationEntry[] getAnnotationEntries()
    Returns:
      Annotations on the field or method
    Since:
      6.0

  - ### getAttributes

    public final Attribute[] getAttributes()
    Returns:
      Collection of object attributes.

  - ### getConstantPool

    public final ConstantPool getConstantPool()
    Returns:
      Constant pool used by this object.

  - ### getGenericSignature

    public final String getGenericSignature()
    Hunts for a signature attribute on the member and returns its contents. So where the 'regular' signature may be (Ljava/util/Vector;)V the signature attribute may in fact say 'Ljava/lang/Vector<Ljava/lang/String>;' Coded for performance - searches for the attribute only when requested - only searches for it once.
    Since:
      6.0

  - ### getName

    public final String getName()
    Returns:
      Name of object, i.e., method name or field name

  - ### getNameIndex

    public final int getNameIndex()
    Returns:
      Index in constant pool of object's name.

  - ### getSignature

    public final String getSignature()
    Returns:
      String representation of object's type signature (Java style)

  - ### getSignatureIndex

    public final int getSignatureIndex()
    Returns:
      Index in constant pool of field signature.

  - ### setAttributes

    public final void setAttributes(Attribute[] attributes)
    Parameters:
      `attributes` - Collection of object attributes.

  - ### setConstantPool

    public final void setConstantPool(ConstantPool constantPool)
    Parameters:
      `constantPool` - Constant pool to be used for this object.

  - ### setNameIndex

    public final void setNameIndex(int nameIndex)
    Parameters:
      `nameIndex` - Index in constant pool of object's name.

  - ### setSignatureIndex

    public final void setSignatureIndex(int signatureIndex)
    Parameters:
      `signatureIndex` - Index in constant pool of field signature.
