decodeLoop back to summary

decodeLoop	back to summary
protected CoderResult decodeLoop(ByteBuffer src, CharBuffer dst) Implements abstract java.nio.charset.CharsetDecoder.decodeLoop. Doc from java.nio.charset.CharsetDecoder.decodeLoop. Decodes one or more bytes into one or more characters. This method encapsulates the basic decoding loop, decoding as many bytes as possible until it either runs out of input, runs out of room in the output buffer, or encounters a decoding error. This method is invoked by the `decode` method, which handles result interpretation and error recovery. The buffers are read from, and written to, starting at their current positions. At most `in.remaining()` bytes will be read, and at most `out.remaining()` characters will be written. The buffers' positions will be advanced to reflect the bytes read and the characters written, but their marks and limits will not be modified. This method returns a `CoderResult` object to describe its reason for termination, in the same manner as the `decode` method. Most implementations of this method will handle decoding errors by returning an appropriate result object for interpretation by the `decode` method. An optimized implementation may instead examine the relevant error action and implement that action itself. An implementation of this method may perform arbitrary lookahead by returning `CoderResult#UNDERFLOW` until it receives sufficient input.

canEncode	back to summary
public boolean canEncode(char c) Overrides java.nio.charset.CharsetEncoder.canEncode. Doc from java.nio.charset.CharsetEncoder.canEncode. Tells whether or not this encoder can encode the given character. This method returns `false` if the given character is a surrogate character; such characters can be interpreted only when they are members of a pair consisting of a high surrogate followed by a low surrogate. The `canEncode(CharSequence)` method may be used to test whether or not a character sequence can be encoded. This method may modify this encoder's state; it should therefore not be invoked if an encoding operation is already in progress. The default implementation of this method is not very efficient; it should generally be overridden to improve performance.
