Examples with ContentCodec io.servicetalk.encoding.api.ContentCodec used on opensource projects

Example 1 with ContentCodec

use of io.servicetalk.encoding.api.ContentCodec in project servicetalk by apple.

the class HeaderUtils method identifyContentEncodingOrNullIfIdentity.

/**
 * Attempts to identify the {@link ContentCodec} from a name, as found in the {@code 'Content-Encoding'}
 * header of a request or a response.
 * If the name can not be matched to any of the supported encodings on this endpoint, then
 * a {@link UnsupportedContentEncodingException} is thrown.
 * If the matched encoding is {@link Identity#identity()} then this returns {@code null}.
 * @param headers The headers to read the encoding name from
 * @param allowedEncodings The supported encodings for this endpoint
 * @return The {@link ContentCodec} that matches the name or null if matches to identity
 * @deprecated Will be removed along with {@link ContentCodec}.
