Example 11 with TemporalInstant

use of org.apache.rya.indexing.TemporalInstant in project incubator-rya by apache.

the class AccumuloTemporalIndexer method storeStatement.

/**
 * Store a statement in the index if it meets the criterion: Object should be
 * a literal and one of the validPredicates from the configuration.
 * If it does not meet the criteria, it is silently ignored.
 * logs a warning if the object is not parse-able.
 * Attempts to parse with calendarValue = literalValue.calendarValue()
 * if that fails, tries: org.joda.time.DateTime.parse() .
 * T O D O parse an interval using multiple predicates for same subject -- ontology dependent.
