List of one() Examples

Examples of one()

com.datastax.driver.core.ResultSet.one()
Returns the next result from this ResultSet. @return the next row in this resultSet or null if this ResultSet isexhausted.
com.mongodb.DBCursor.one()
Returns the first document that matches the query. @return the first matching document @since 2.12
com.tinkerpop.gremlin.driver.ResultSet.one()
Get the next {@link Result} from the stream, blocking until one is available.
edu.cmu.sphinx.fst.semiring.Semiring.one()
Semiring's one element
kodkod.ast.Expression.one()
Returns the formula 'one this'. The effect of this method is the same as calling this.apply(ONE). @return this.apply(ONE)
kodkod.engine.bool.BooleanMatrix.one()
Returns a BooleanValue that constraints exactly one value in this.elements to be true. @return { f: BooleanValue | f <=> #this.elements[int] = 1 }
org.apache.cassandra.cql3.UntypedResultSet.one()
org.sgx.yuigwt.yui.node.Node.one()
selects one node that match the selector relative to this node. @param sel @return
org.sgx.yuigwt.yuigallery.YuiGalleryContext.one()
ptolemy.data.Token.one()
Returns a new Token representing the multiplicative identity. It should be overridden in subclasses. @exception IllegalActionException If this method is notsupported by the derived class. @return A new Token containing the multiplicative identity.If this token is a nil token, then {@link #NIL} is returned.
