Member Data Documentation

bool madara::knowledge::KnowledgeRequirements::clear_knowledge

If true, during loads, clear the KnowledgeBase first.

Definition at line 89 of file KnowledgeRequirements.h.

uint64_t madara::knowledge::KnowledgeRequirements::clock_threshold

Minimum acceptable clock to accept (0 by default)

Definition at line 94 of file KnowledgeRequirements.h.

std::vector<MatchPredicate> madara::knowledge::KnowledgeRequirements::predicates

A vector of acceptable predicates to match (prefix and suffix).

Empty elements mean "match all". Consequently, if you have a a predicate with a prefix of "" and a suffix of "", this would simply mean match all records. If you have a prefix of "agent", and an empty suffix, then all variables that start with "agent" will be accepted in the operation. Matching suffixes is more computationally expensive, as it forces all variables to be evaluated. If at all possible, use prefixes. Only use suffixes to filter out prefix results.

Definition at line 107 of file KnowledgeRequirements.h.

uint64_t madara::knowledge::KnowledgeRequirements::quality_threshold

Minimum acceptable knowledge qualilty to accept (0 by default)

Definition at line 112 of file KnowledgeRequirements.h.

bool madara::knowledge::KnowledgeRequirements::use_source_clock

Update to the Lamport Clock of the source.
