Method Detail

getInstance

public static ASN1ApplicationSpecific getInstance(java.lang.Object obj)

Return an ASN1ApplicationSpecific from the passed in object, which may be a byte array, or null.

Parameters:

obj - the object to be converted.

Returns:

obj's representation as an ASN1ApplicationSpecific object.

getApplicationTag

public int getApplicationTag()

Return the tag number associated with this object,

Returns:

the application tag number.

getContents

public byte[] getContents()

Return the contents of this object as a byte[]

Returns:

the encoded contents of the object.

getLoadedObject

public final ASN1Primitive getLoadedObject()

Description copied from interface: InMemoryRepresentable

Get the in-memory representation of the ASN.1 object.

Specified by:

getLoadedObject in interface InMemoryRepresentable

Returns:

an ASN1Primitive representing the loaded object.

getObject

public ASN1Primitive getObject()
                        throws java.io.IOException

Deprecated. Will be removed. Use getEnclosedObject() instead.

Return the enclosed object assuming explicit tagging.

Returns:

the resulting object

Throws:

java.io.IOException - if reconstruction fails.

getEnclosedObject

public ASN1Primitive getEnclosedObject()
                                throws java.io.IOException

Return the enclosed object assuming explicit tagging.

Returns:

the resulting object

Throws:

java.io.IOException - if reconstruction fails.

getObject

public ASN1Primitive getObject(int tagNo)
                        throws java.io.IOException

Return the enclosed object assuming implicit tagging.

Parameters:

tagNo - the type tag that should be applied to the object's contents.

Returns:

the resulting object

Throws:

java.io.IOException - if reconstruction fails.

getObjectParser

public ASN1Encodable getObjectParser(int tag,
                                     boolean isExplicit)
                              throws java.io.IOException

Description copied from interface: ASN1TaggedObjectParser

Return a parser for the actual object tagged.

Specified by:

getObjectParser in interface ASN1TaggedObjectParser

Parameters:

tag - the primitive tag value for the object tagged originally.

isExplicit - true if the tagging was done explicitly.

Returns:

a parser for the tagged object.

Throws:

java.io.IOException - if a parser cannot be constructed.

parseBaseUniversal

public ASN1Encodable parseBaseUniversal(boolean declaredExplicit,
                                        int baseTagNo)
                                 throws java.io.IOException

Specified by:

parseBaseUniversal in interface ASN1TaggedObjectParser

Throws:

java.io.IOException

parseExplicitBaseObject

public ASN1Encodable parseExplicitBaseObject()
                                      throws java.io.IOException

Description copied from interface: ASN1TaggedObjectParser

Needed for open types, until we have better type-guided parsing support. Use sparingly for other purposes, and prefer ASN1TaggedObjectParser.parseExplicitBaseTagged() or ASN1TaggedObjectParser.parseBaseUniversal(boolean, int) where possible. Before using, check for matching tag class and number.

Specified by:

parseExplicitBaseObject in interface ASN1TaggedObjectParser

Throws:

java.io.IOException

parseExplicitBaseTagged

public ASN1TaggedObjectParser parseExplicitBaseTagged()
                                               throws java.io.IOException

Specified by:

parseExplicitBaseTagged in interface ASN1TaggedObjectParser

Throws:

java.io.IOException

parseImplicitBaseTagged

public ASN1TaggedObjectParser parseImplicitBaseTagged(int baseTagClass,
                                                      int baseTagNo)
                                               throws java.io.IOException

Specified by:

parseImplicitBaseTagged in interface ASN1TaggedObjectParser

Throws:

java.io.IOException

getTagClass

public int getTagClass()

Description copied from interface: ASN1TaggedObjectParser

Return the tag class associated with this object.

Specified by:

getTagClass in interface ASN1TaggedObjectParser

Returns:

the tag class.

getTagNo

public int getTagNo()

Description copied from interface: ASN1TaggedObjectParser

Return the tag number associated with this object.

Specified by:

getTagNo in interface ASN1TaggedObjectParser

Returns:

the tag number.

hasApplicationTag

public boolean hasApplicationTag(int tagNo)

hasContextTag

public boolean hasContextTag(int tagNo)

Specified by:

hasContextTag in interface ASN1TaggedObjectParser

hasTag

public boolean hasTag(int tagClass,
                      int tagNo)

Specified by:

hasTag in interface ASN1TaggedObjectParser

getTaggedObject

public ASN1TaggedObject getTaggedObject()

ASN1ApplicationSpecific uses an internal ASN1TaggedObject for the implementation, and will soon be deprecated in favour of using ASN1TaggedObject with a tag class of BERTags.APPLICATION. This method lets you get the internal ASN1TaggedObject so that client code can begin the migration.

hashCode

public int hashCode()

Specified by:

hashCode in class ASN1Primitive

isConstructed

public boolean isConstructed()

Return true if the object is marked as constructed, false otherwise.

Returns:

true if constructed, otherwise false.

Description copied from interface: ASN1ApplicationSpecificParser

Read the next object in the parser.

Specified by:

readObject in interface ASN1ApplicationSpecificParser

Returns:

an ASN1Encodable

Throws:

java.io.IOException - on a parsing or decoding error.
