public final class ChangeStatusPredicate
extends ChangeIndexPredicate
implements HasCardinality

Predicate for a Change.Status.

The actual name of this operator can differ, it usually comes as status: but may also be is: to help do-what-i-meanery for end-users searching for changes. Either operator name has the same meaning.

Status names are looked up by prefix case-insensitively.

Method Detail

canonicalize

public static String canonicalize(Change.Status status)

parse

public static Predicate<ChangeData> parse(String value)
                                   throws QueryParseException

Throws:

QueryParseException

open

public static Predicate<ChangeData> open()

closed

public static Predicate<ChangeData> closed()

forStatus

public static ChangeStatusPredicate forStatus(Change.Status status)

getStatus

public Change.Status getStatus()

Get the status for this predicate.

Returns:

the status, or null if this predicate is intended to never match any changes.

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:

equals

public boolean equals(Object other)

Overrides:

equals in class OperatorPredicate<ChangeData>

toString

public String toString()

toString in class OperatorPredicate<ChangeData>

getCardinality

public int getCardinality()

Description copied from interface: HasCardinality

Returns an estimate of the number of results a source can return.
