Class CommonsCompressCodecFactory

java.lang.Object

org.apache.hc.client5.http.entity.compress.CommonsCompressCodecFactory

@Internal
@Contract(threading=STATELESS)
final class CommonsCompressCodecFactory
extends Object

Codecs factory for Apache Commons Compress.

Use runtimeAvailable(ContentCoding) to probe whether a given coding can be provided by the current classpath configuration. Callers can then register codecs conditionally without hard dependencies.

Method Details

isPresent

private static boolean isPresent(String className)

decoder

static org.apache.hc.core5.io.IOFunction<InputStream, InputStream> decoder(String token)

Creates a lazy decoder that instantiates the Commons Compress stream.

encoder

static org.apache.hc.core5.io.IOFunction<OutputStream, OutputStream> encoder(String token)

Creates a lazy encoder that instantiates the Commons Compress stream.

runtimeAvailable

static boolean runtimeAvailable(ContentCoding coding)

Best-effort availability probe for optional Commons-Compress codecs.

Returns true only if the CC factory and the codec-specific implementation (and helper classes if required) are present on the classpath. Built-in gzip/deflate are handled elsewhere and are not probed here.
