Class DCDStreamingTermStore

java.lang.Object

org.linqs.psl.reasoner.term.streaming.StreamingTermStore<DCDObjectiveTerm>

org.linqs.psl.reasoner.dcd.term.DCDStreamingTermStore

All Implemented Interfaces:

Iterable<DCDObjectiveTerm>, TermStore<DCDObjectiveTerm,GroundAtom>, VariableTermStore<DCDObjectiveTerm,GroundAtom>

public class DCDStreamingTermStore
extends StreamingTermStore<DCDObjectiveTerm>

A term store that iterates over ground queries directly (obviating the GroundRuleStore). Note that the iterators given by this class are meant to be exhaustd (at least the first time). Remember that this class will internally iterate over an unknown number of groundings. So interrupting the iteration can cause the term count to be incorrect.

Constructor Detail

DCDStreamingTermStore

public DCDStreamingTermStore(List<Rule> rules,
                             AtomManager atomManager,
                             DCDTermGenerator dcdTermGenerator)

Method Detail

supportsRule

protected boolean supportsRule(Rule rule,
                               boolean warnRules)

Description copied from class: StreamingTermStore

Check if this term store supports this rule. If the rule is not supported and |warnRules| is true, then a warning should be logged.

Overrides:

supportsRule in class StreamingTermStore<DCDObjectiveTerm>

Returns:

true if the rule is supported.

getGroundingIterator

protected StreamingIterator<DCDObjectiveTerm> getGroundingIterator()

Description copied from class: StreamingTermStore

Get an iterator that will perform grounding queries and write pages to disk. By default, this is only called for the initial round of iteration, but children may override call this in different situations (like online inference).

Specified by:

getGroundingIterator in class StreamingTermStore<DCDObjectiveTerm>

getCacheIterator

protected StreamingIterator<DCDObjectiveTerm> getCacheIterator()

Description copied from class: StreamingTermStore

Get an iterator that will read and write from disk.

Specified by:

getCacheIterator in class StreamingTermStore<DCDObjectiveTerm>

getNoWriteIterator

protected StreamingIterator<DCDObjectiveTerm> getNoWriteIterator()

Description copied from class: StreamingTermStore

Get an iterator that will not write to disk.

Specified by:

getNoWriteIterator in class StreamingTermStore<DCDObjectiveTerm>
