public abstract class ASN1Primitive
extends ASN1Object

Base class for ASN.1 primitive objects. These are the actual objects used to generate byte encodings.

Method Summary

void	encodeTo(java.io.OutputStream output, java.lang.String encoding)
boolean	equals(java.lang.Object o)
boolean	equals(ASN1Encodable other)
boolean	equals(ASN1Primitive other)
static ASN1Primitive	fromByteArray(byte[] data)	Parse an ASN.1 (BER) encoding from a byte array.
static ASN1Primitive	fromStream(java.io.InputStream input)	Parse the first ASN.1 (BER) encoding from an InputStream.The stream is not closed by this method and may contain further data beyond the first ASN.1 encoding.
abstract int	hashCode()
ASN1Primitive	toASN1Primitive()	Method providing a primitive representation of this object suitable for encoding.

Method Detail

encodeTo

public void encodeTo(java.io.OutputStream output)
              throws java.io.IOException

Overrides:

encodeTo in class ASN1Object

Throws:

java.io.IOException

encodeTo

public void encodeTo(java.io.OutputStream output,
                     java.lang.String encoding)
              throws java.io.IOException

Overrides:

encodeTo in class ASN1Object

Throws:

java.io.IOException

fromByteArray

public static ASN1Primitive fromByteArray(byte[] data)
                                   throws java.io.IOException

Parse an ASN.1 (BER) encoding from a byte array. Checks there are no extra bytes following the encoding.

Parameters:

data - the byte array to parse.

Returns:

the base ASN.1 object parsed from the byte array.

Throws:

java.io.IOException - if there is a problem parsing the data, or parsing did not exhaust the available data.

fromStream

public static ASN1Primitive fromStream(java.io.InputStream input)
                                throws java.io.IOException

Parse the first ASN.1 (BER) encoding from an InputStream.The stream is not closed by this method and may contain further data beyond the first ASN.1 encoding.

Parameters:

data - the stream to parse.

Returns:

the base ASN.1 object parsed from the stream.

Throws:

java.io.IOException - if there is a problem parsing the data.

equals

public final boolean equals(java.lang.Object o)

Overrides:

equals in class ASN1Object

equals

public final boolean equals(ASN1Encodable other)

equals

public final boolean equals(ASN1Primitive other)

toASN1Primitive

public final ASN1Primitive toASN1Primitive()

Description copied from class: ASN1Object

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

Specified by:

toASN1Primitive in interface ASN1Encodable

Specified by:

toASN1Primitive in class ASN1Object

Returns:

a primitive representation of this object.

hashCode

public abstract int hashCode()

Overrides:

hashCode in class ASN1Object
