Detailed Description

This interface is a base interface for all classes, which implement an input stream functionality for decoding.

Member Function Documentation

Available()

int Available

(

)

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.

Returns

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

Exceptions

System.SystemException

if an I/O error occurs.

Implemented in Asn1PerInputStream, Asn1BerInputStream, Asn1DerInputStream, and Asn1MderDecodeBuffer.

Close()

void Close

(

)

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

Exceptions

System.SystemException

if an I/O error occurs.

Implemented in Asn1PerInputStream, Asn1BerInputStream, Asn1DerInputStream, and Asn1MderDecodeBuffer.

Mark()

void Mark

(

)

This method is used to mark the current position in the input stream for retry processing or reseting the input stream position to current position.

Implemented in Asn1PerInputStream, Asn1BerInputStream, and Asn1DerInputStream.

MarkSupported()

bool MarkSupported

(

)

Tests if this input stream supports the seeking. This method is equivalent to C# CanSeek method of System.IO.Stream.

Returns

true if input stream supports seeking; Otherwise false.

Implemented in Asn1PerInputStream, Asn1BerInputStream, Asn1DerInputStream, and Asn1MderDecodeBuffer.

Reset()

void Reset

(

)

This method is used to reset the current position in the input stream back to the location of the last 'mark' call. It is equivalent to calling 'Stream.Position' to marked location.

Implemented in Asn1PerInputStream, Asn1BerInputStream, and Asn1DerInputStream.

Skip()

long Skip

(

long

nbytes

)

This method will skip over the requested number of bytes in the input stream.

Parameters

nbytes

Number of bytes to skip

Exceptions

System.SystemException

if an I/O error occurs.

Returns

Skipped number of bytes

Implemented in Asn1PerInputStream, Asn1BerInputStream, and Asn1DerInputStream.
