Method Detail

match

public boolean match(ChangeData object)

Description copied from class: IndexPredicate

This method matches documents without calling an index subsystem. For primitive fields (e.g. integer, long) , the matching logic is consistent across this method and all known index implementations. For text fields (i.e. prefix and full-text) the semantics vary between this implementation and known index implementations:

Prefix: Lucene as well as IndexPredicate.match(Object) matches terms as true prefixes (prefix:foo -> `foo bar` matches, but `baz foo bar` does not match). The index implementation at Google tokenizes both the query and the indexed text and matches tokens individually (prefix:fo ba -> `baz foo bar` matches). Full text: Lucene uses a PhraseQuery to search for terms in full text fields in-order. The index implementation at Google as well as IndexPredicate.match(Object) tokenizes both the query and the indexed text and matches tokens individually.

Specified by:

match in interface Matchable<ChangeData>

Overrides:

match in class IndexPredicate<ChangeData>

Returns:

true if the predicate matches the provided I.

type

protected static LabelType type(LabelTypes types,
                                String toFind)

match

protected boolean match(ChangeData cd,
                        short value,
                        Account.Id approver)

getCost

public int getCost()

Description copied from interface: Matchable

Returns a cost estimate to run this predicate, higher figures cost more.

Specified by:

getCost in interface Matchable<ChangeData>

Overrides:

getCost in class IndexPredicate<ChangeData>
