Examples of CoderResult

java.nio.charset.CoderResult
Used to indicate the result of encoding/decoding. There are four types of results:
1. UNDERFLOW indicates all input has been processed, or more input is required. It is represented by the unique object CoderResult.UNDERFLOW.
2. OVERFLOW indicates insufficient output buffer. It is represented by the unique object CoderResult.OVERFLOW.
3. A malformed-input error indicates an unrecognizable sequence of input units has been encountered. Get an instance of this type of result by calling CoderResult.malformedForLength(int) with the length of the malformed-input.
4. An unmappable-charactor error indicates a sequence of input units can not be mapped to the output charset. Get an instance of this type of result by calling CoderResult.unmappableForLength(int) with the input sequence size indicating the identity of the unmappable character.
