encode

public void encode(Integer value,
                   OutputStream outStream,
                   Coder.Context context)
            throws IOException,
                   CoderException

Description copied from interface: Coder

Encodes the given value of type T onto the given output stream in the given context.

Throws:

IOException - if writing to the OutputStream fails for some reason

CoderException - if the value could not be encoded for some reason

decode

public Integer decode(InputStream inStream,
                      Coder.Context context)
               throws IOException,
                      CoderException

Description copied from interface: Coder

Decodes a value of type T from the given input stream in the given context. Returns the decoded value.

Throws:

IOException - if reading from the InputStream fails for some reason

CoderException - if the value could not be decoded for some reason

verifyDeterministic

public void verifyDeterministic()

Description copied from class: DeterministicStandardCoder

As a DeterministicStandardCoder is presumed deterministic, this method does nothing.

Specified by:

verifyDeterministic in interface Coder<Integer>

Overrides:

verifyDeterministic in class DeterministicStandardCoder<Integer>

getEncodedElementByteSize

protected long getEncodedElementByteSize(Integer value,
                                         Coder.Context context)
                                  throws Exception

Description copied from class: StandardCoder

Returns the size in bytes of the encoded value using this coder. Derived classes override this method if byte size can be computed with less computation or copying.

Overrides:

getEncodedElementByteSize in class StandardCoder<Integer>

Throws:

Exception
