Method Details

decode

public static io.reactivex.rxjava3.core.FlowableTransformer<ByteBuffer,CharBuffer> decode(Charset charset)

Decodes a flow of ByteBuffer into a flow of CharBuffer using the given Charset.

This transformer uses a CharsetDecoder configured to replace malformed and unmappable characters in order to behave as closely as possible to the JDK InputStreamReader.

The output char buffers will be new unpooled buffers.

Parameters:

charset - the target decoding charset

Returns:

a flowable transformer of ByteBuffer to CharBuffer

decode

public static io.reactivex.rxjava3.core.FlowableTransformer<ByteBuffer,CharBuffer> decode(Supplier<CharsetDecoder> decoderSupplier)

Decodes a flow of ByteBuffer into a flow of CharBuffer using the given CharsetDecoder supplier.

This transformer uses default's capacity for the working copy and decoded buffers (respectively 8192 and 8192). Decoded buffers are unpooled.

Parameters:

decoderSupplier - a supplier of the charset decoder to use

Returns:

a flowable transformer of ByteBuffer to CharBuffer

decode

public static io.reactivex.rxjava3.core.FlowableTransformer<ByteBuffer,CharBuffer> decode(Supplier<CharsetDecoder> decoderSupplier,
 int workingByteBufferCapacity,
 Supplier<CharBuffer> outputBufferSupplier)

Decodes a flow of ByteBuffer into a flow of CharBuffer using the given CharBuffer and CharsetDecoder suppliers.

Parameters:

decoderSupplier - a supplier of the charset decoder to use

workingByteBufferCapacity - Size of the working copy ByteBuffer (greater than 32)

outputBufferSupplier - a supplier of the decoded CharBuffer

Returns:

a flowable transformer of ByteBuffer to CharBuffer
