Direct Known Subclasses:

ExternalSignature, InternalSignature

public abstract class Signature
extends Object

This class encapsulates information about format signatures, both internal and external. The value of a Signature may be either a String or a byte array (stored as an int array to avoid signed byte problems).

Constructor Detail

Signature

protected Signature(String value,
                    SignatureType type,
                    SignatureUseType use)

A Signature cannot be created directly; this constructor can be called as the superclass constructor from a subclass. This constructor uses a String value.

Signature

protected Signature(int[] value,
                    SignatureType type,
                    SignatureUseType use)

A Signature cannot be created directly; this constructor can be called as the superclass constructor from a subclass. This constructor uses a byte array (stored as an int array) value.

Signature

protected Signature(String value,
                    SignatureType type,
                    SignatureUseType use,
                    String note)

A Signature cannot be created directly; this constructor can be called as the superclass constructor from a subclass. This constructor uses a String value and allows specification of a note.

Signature

protected Signature(int[] value,
                    SignatureType type,
                    SignatureUseType use,
                    String note)

A Signature cannot be created directly; this constructor can be called as the superclass constructor from a subclass. This constructor uses a byte array (stored as an int array) value and allows specification of a note.

Method Detail

getType

public SignatureType getType()

Returns the type of this Signature

getUse

public SignatureUseType getUse()

Returns the use requirement for this Signature

getValue

public int[] getValue()

Returns the byte array value for this Signature. If this Signature was constructed from a String, it returns the characters of the String as the bytes of the array.

getNote

public String getNote()

Returns the note specified for this Signature, or null if no note was specified.

isStringValue

public boolean isStringValue()

Returns true if this Signature's value was provided as a String, false if as an array.

getValueString

public String getValueString()

Returns the string value of this Signature. Returns null if this Signature was constructed with an array.

getValueHexString

public String getValueHexString()

Returns the value of this Signature as a hexadecimal string. The length of the string is twice the length of the array or string from which this Signature was created, and all alphabetic characters are lower case.
