Returns:

An instance of the parsed value type.

public ByteValue getLastResult()

Description copied from class: FieldParser

Gets the parsed field. This method returns the value parsed by the last successful invocation of FieldParser.parseField(byte[], int, int, byte[], Object). It objects are mutable and reused, it will return the object instance that was passed the parse function.

Specified by:

getLastResult in class FieldParser<ByteValue>

Returns:

The latest parsed field.
