Method Detail

getCurrentLength

int getCurrentLength()

Get the current object length, which is the sum of all inner length already decoded.

Returns:

The current object's length

computeLength

int computeLength()

Compute the object length, which is the sum of all inner length.

Returns:

The object's computed length

encode

ByteBuffer encode(ByteBuffer buffer)
                  throws EncoderException

Encode the object to a PDU.

Parameters:

buffer - The buffer where to put the PDU

Returns:

The PDU.

Throws:

EncoderException - if the buffer can't be encoded

getExpectedLength

int getExpectedLength()

Get the expected object length.

Returns:

The expected object's length

addLength

void addLength(int length)
               throws DecoderException

Add a length to the object

Parameters:

length - The length to add.

Throws:

DecoderException - Thrown if the current length exceed the expected length

setExpectedLength

void setExpectedLength(int expectedLength)

Set the expected length

Parameters:

expectedLength - The expectedLength to set.

setCurrentLength

void setCurrentLength(int currentLength)

Set the current length

Parameters:

currentLength - The currentLength to set.

getParent

Asn1Object getParent()

Get the parent

Returns:

Returns the parent.
