Class ASN1InputStream
java.lang.Object
java.io.InputStream
java.io.FilterInputStream
org.apache.geronimo.util.asn1.ASN1InputStream
- All Implemented Interfaces:
- Closeable, DERTags
public class ASN1InputStream
- extends FilterInputStream
- implements DERTags
a general purpose ASN.1 decoder - note: this class differs from the
others in that it returns null after it has read the last object in
the stream. If an ASN.1 NULL is encountered a DER/BER Null object is
returned.
