Method Detail

readByte

public int readByte()
             throws Asn1Exception,
                    java.io.IOException

Description copied from class: Asn1DecodeBuffer

This abstract method returns the next available 8-bit value from the input stream. It is implemented differently for BER/DER and PER to take into account odd alignments in PER.

Specified by:

readByte in class Asn1DecodeBuffer

Returns:

Next 8-bit byte value from input stream

Throws:

Asn1Exception

java.io.IOException

available

public int available()
              throws java.io.IOException

Description copied from interface: Asn1InputStream

Returns the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream. The next caller might be the same thread or or another thread.

Specified by:

available in interface Asn1InputStream

Returns:

the number of bytes that can be read from this input stream without blocking.

Throws:

java.io.IOException - if an I/O error occurs.

close

public void close()
           throws java.io.IOException

Description copied from interface: Asn1InputStream

Closes this input stream and releases any system resources associated with the stream.

Specified by:

close in interface Asn1InputStream

Throws:

java.io.IOException - if an I/O error occurs.

markSupported

public boolean markSupported()

Description copied from interface: Asn1InputStream

Tests if this input stream supports the mark and reset methods. The markSupported method of InputStream returns false.

Specified by:

markSupported in interface Asn1InputStream

Returns:

true if this true type supports the mark and reset method; false otherwise.
