Field Detail

TEXT_MAP

public static final Format<TextMap> TEXT_MAP

The TEXT_MAP format allows for arbitrary String->String map encoding of SpanContext state for Tracer.inject and Tracer.extract. Unlike HTTP_HEADERS, the builtin TEXT_MAP format expresses no constraints on keys or values.

See Also:

Tracer.inject(SpanContext, Format, Object), Tracer.extract(Format, Object), Format, HTTP_HEADERS

HTTP_HEADERS

public static final Format<TextMap> HTTP_HEADERS

The HTTP_HEADERS format allows for HTTP-header-compatible String->String map encoding of SpanContext state for Tracer.inject and Tracer.extract. I.e., keys written to the TextMap MUST be suitable for HTTP header keys (which are poorly defined but certainly restricted); and similarly for values (i.e., URL-escaped and "not too long").

Tracer.inject(SpanContext, Format, Object), Tracer.extract(Format, Object), Format, TEXT_MAP

BINARY

public static final Format<ByteBuffer> BINARY

The BINARY format allows for unconstrained binary encoding of SpanContext state for Tracer.inject and Tracer.extract.
