Member Function Documentation

add_metadata()

void sensesp::SKEmitter::add_metadata ( JsonArray &  meta )

virtual

Adds this emitter's Signal K meta data to the specified meta object. The default implementation calls the add_entry() method of the SKMetadata class returned by get_metadata(). If get_metadata() returns NULL, this method does nothing.

Here is the call graph for this function:

as_signalk()

virtual String sensesp::SKEmitter::as_signalk ( )

inlinevirtual

Returns the data to be reported to the server as a Signal K json string.

Reimplemented in sensesp::SKOutput< T >, sensesp::SKOutput< String >, sensesp::SKOutput< T >, sensesp::SKOutput< String >, sensesp::SKOutput< T >, sensesp::SKOutput< String >, sensesp::SKOutputRawJson, and sensesp::SKOutputTime.

Definition at line 34 of file signalk_emitter.h.

get_metadata()

virtual SKMetadata * sensesp::SKEmitter::get_metadata ( )

inlinevirtual

Returns a Metadata structure that describes the sk_path this SKEmitter is associated with. If this emitter has no metadata, NULL is returned.

Here is the caller graph for this function:

get_sk_path()

String & sensesp::SKEmitter::get_sk_path ( )

inline

Returns the current Signal K path. An empty string is returned if this particular source is not configured or intended to return actual data.
