Method Detail

getEncoded

public byte[] getEncoded()
                  throws IOException

Return the default BER or DER encoding for this object.

Specified by:

getEncoded in interface Encodable

Returns:

BER/DER byte encoded object.

Throws:

IOException - on encoding error.

getEncoded

public byte[] getEncoded(String encoding)
                  throws IOException

Return either the default for "BER" or a DER encoding if "DER" is specified.

Parameters:

encoding - name of encoding to use.

Returns:

byte encoded object.

Throws:

IOException - on encoding error.

hashCode

public int hashCode()

Description copied from class: Object

Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Overrides:

hashCode in class Object

Returns:

this object's hash code.

See Also:

Object.equals(java.lang.Object)

equals

public boolean equals(Object o)

Description copied from class: Object

Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

The general contract for the equals and Object.hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

Overrides:

equals in class Object

Parameters:

o - the object to compare this instance with.

Returns:

true if the specified object is equal to this Object; false otherwise.

See Also:

Object.hashCode()

toASN1Object

public ASN1Primitive toASN1Object()

Deprecated. use toASN1Primitive()

Returns:

the underlying primitive type.

hasEncodedTagValue

protected static boolean hasEncodedTagValue(Object obj,
                                            int tagValue)

Return true if obj is a byte array and represents an object with the given tag value.

Parameters:

obj - object of interest.

tagValue - tag value to check for.

Returns:

true if obj is a byte encoding starting with the given tag value, false otherwise.

toASN1Primitive

public abstract ASN1Primitive toASN1Primitive()

Method providing a primitive representation of this object suitable for encoding.

Specified by:

toASN1Primitive in interface ASN1Encodable

Returns:

a primitive representation of this object.
