encode

public void encode(PaneInfo value,
                   java.io.OutputStream outStream)
            throws CoderException,
                   java.io.IOException

Description copied from class: Coder

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

Specified by:

encode in class Coder<PaneInfo>

Throws:

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

java.io.IOException - if writing to the OutputStream fails for some reason

decode

public PaneInfo decode(java.io.InputStream inStream)
                throws CoderException,
                       java.io.IOException

Description copied from class: Coder

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

Specified by:

decode in class Coder<PaneInfo>

Throws:

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

java.io.IOException - if reading from the InputStream fails for some reason

verifyDeterministic

public void verifyDeterministic()

Description copied from class: AtomicCoder

Throw Coder.NonDeterministicException if the coding is not deterministic.

In order for a Coder to be considered deterministic, the following must be true:

• two values that compare as equal (via Object.equals() or Comparable.compareTo(), if supported) have the same encoding.
• the Coder always produces a canonical encoding, which is the same for an instance of an object even if produced on different computers at different times.

.

Unless overridden, does not throw. An AtomicCoder is presumed to be deterministic

Overrides:

verifyDeterministic in class AtomicCoder<PaneInfo>
