Function Documentation

madara::knowledge::KnowledgeRecord madara::filters::discard	(	knowledge::FunctionArguments &	args,
		knowledge::Variables &	vars
	)

Filter for discarding a record.

Resulting record will have a status of UNCREATED.

Parameters

args	arguments to the filter (unused)
vars	variable context (unused)

Returns

record with status set to UNCREATED

Definition at line 16 of file GenericFilters.cpp.

madara::knowledge::KnowledgeRecord madara::filters::discard_nonfiles	(	knowledge::FunctionArguments &	args,
		knowledge::Variables &	vars
	)

Filter for discarding a non-file record.

Resulting record will have a status of UNCREATED. Files are IMAGE_JPEG, TEXT, XML, and UNKNOWN_FILE_TYPE.

Parameters

args	filter arguments (only first argument is used)
vars	variable context

Returns

record with status set to UNCREATED if arg is non-file

Alternatively, we could check type () for each defined type, but this will check that we are a file type

At the transport layer, we should check for stripped types and remove them from the list of knowledge records

Definition at line 51 of file GenericFilters.cpp.

madara::knowledge::KnowledgeRecord madara::filters::discard_nonprimitives	(	knowledge::FunctionArguments &	args,
		knowledge::Variables &	vars
	)

Filter for discarding a non-primitive record.

Resulting record will have a status of UNCREATED. Primitives are INTEGER, DOUBLE, STRING, INTEGER_ARRAY, and DOUBLE_ARRAY.

Parameters

args	filter arguments (only first argument is used)
vars	variable context (unused)

Returns

record with status set to UNCREATED if arg is non-primitive

Alternatively, we could check type () for each defined type, but this will check that we are not a file type

At the transport layer, we should check for stripped types and remove them from the list of knowledge records

Definition at line 24 of file GenericFilters.cpp.

void madara::filters::log_aggregate	(	knowledge::KnowledgeMap &	records,
		const transport::TransportContext &	transport_context,
		knowledge::Variables &	vars
	)

Filter for logging aggregate update and context.

Parameters

records	aggregate update
transport_context	the transport context
vars	variable context

Definition at line 142 of file GenericFilters.cpp.

madara::knowledge::KnowledgeRecord madara::filters::log_args	(	knowledge::FunctionArguments &	args,
		knowledge::Variables &	vars
	)

Filter for logging args.

Parameters

args	filter arguments (only first argument is used)
vars	variable context

Returns

record with status set to UNCREATED if arg is non-file

Definition at line 77 of file GenericFilters.cpp.
