Interface for the parsing of a generic tagged ASN.1 object.

Method Summary

Modifier and Type	Method	Description

boolean	hasContextTag(int tagNo)
boolean	hasTag(int tagClass, int tagNo)
ASN1Encodable	parseBaseUniversal(boolean declaredExplicit, int baseTagNo)
ASN1Encodable	parseExplicitBaseObject()	Needed for open types, until we have better type-guided parsing support.

getLoadedObject

Method Detail

getTagClass

int getTagClass()

Return the tag class associated with this object.

Returns:

the tag class.

getTagNo

int getTagNo()

Return the tag number associated with this object.

Returns:

the tag number.

hasContextTag

boolean hasContextTag(int tagNo)

hasTag

boolean hasTag(int tagClass,
               int tagNo)

getObjectParser

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

Deprecated.

This parser now includes the tag class. This method will raise an exception if it is not BERTags.CONTEXT_SPECIFIC. Use ASN1Util.parseBaseUniversal(ASN1TaggedObjectParser, int, int, boolean, int) as a direct replacement, or use parseBaseUniversal(boolean, int) only after confirming the expected tag class (e.g. ASN1Util.tryParseContextBaseUniversal(ASN1TaggedObjectParser, int, boolean, int).

Return a parser for the actual object tagged.

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

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

Throws:

java.io.IOException

parseExplicitBaseObject

ASN1Encodable parseExplicitBaseObject()
                               throws java.io.IOException

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

Throws:

java.io.IOException

parseExplicitBaseTagged

ASN1TaggedObjectParser parseExplicitBaseTagged()
                                        throws java.io.IOException

Throws:

java.io.IOException

parseImplicitBaseTagged

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

Throws:

java.io.IOException
