Class NuCharsetEncoder

java.lang.Object

com.zaxxer.nuprocess.codec.NuCharsetEncoder

public final class NuCharsetEncoder
extends Object

Implementation of NuProcessHandler.onStdinReady(ByteBuffer) which handles encoding of stdin bytes to Java UTF-16 string data. Calls back into a NuCharsetEncoderHandler with a CharBuffer whose contents will be encoded with a specified Charset or CharsetEncoder then passed to the stdin of a process. This class is not intended to be subclassed.

Constructor Detail

NuCharsetEncoder

public NuCharsetEncoder(NuCharsetEncoderHandler handler,
                        Charset charset)

Creates an encoder which uses a single Charset to encode input data.

Parameters:

handler - NuCharsetEncoderHandler called back with a string buffer to be encoded and fed to stdin

charset - Charset used to encode stdin data to bytes

NuCharsetEncoder

public NuCharsetEncoder(NuCharsetEncoderHandler handler,
                        CharsetEncoder encoder)

Creates an encoder which uses a CharsetEncoder to encode input data.

Parameters:

handler - NuCharsetEncoderHandler called back with a string buffer into which the caller writes string data to be written to stdin

encoder - CharsetEncoder used to encode stdin string data to bytes

Method Detail

onStdinReady

public boolean onStdinReady(ByteBuffer buffer)

Implementation of NuProcessHandler.onStdinReady(ByteBuffer) which calls handler with a string buffer then encodes it to bytes and feeds it to the process's stdin.

Parameters:

buffer - The ByteBuffer passed to NuProcessHandler.onStdinReady(ByteBuffer)

Returns:

true if more data needs to be passed to stdin, false otherwise
