Member Function Documentation

Predicate com.mysql.clusterj.core.query.PredicateImpl.and ( Predicate predicate )

inline

Combine this Predicate with another, using the "and" semantic.

Parameters

predicate the other predicate

Returns: a new Predicate combining both Predicates

Implements com.mysql.clusterj.query.Predicate.

Reimplemented in com.mysql.clusterj.core.query.AndPredicateImpl.

Definition at line 67 of file PredicateImpl.java.

Here is the call graph for this function:

void com.mysql.clusterj.core.query.PredicateImpl.filterCmpValue	(	QueryExecutionContext	context,
		ScanOperation	op
	)

inline

Create a filter for the operation. Set the condition into the new filter.

Parameters

context	the query execution context with the parameter values
op	the operation

Reimplemented in com.mysql.clusterj.core.query.InPredicateImpl, com.mysql.clusterj.core.query.BetweenPredicateImpl, com.mysql.clusterj.core.query.AndPredicateImpl, com.mysql.clusterj.core.query.OrPredicateImpl, and com.mysql.clusterj.core.query.NotPredicateImpl.

Here is the caller graph for this function:

CandidateIndexImpl com.mysql.clusterj.core.query.PredicateImpl.getBestCandidateIndexFor	(	QueryExecutionContext	context,
		PredicateImpl...	predicates
	)

inlineprotected

Get the best candidate index for the query, considering all indices defined and all predicates in the query.

Parameters

predicates the predicates

Returns: the best index for the query

Here is the call graph for this function:

Here is the caller graph for this function:

int com.mysql.clusterj.core.query.PredicateImpl.getNumberOfConditionsInPredicate ( )

inlineprotected

Get the number of conditions in the top level predicate. This is used to determine whether a hash index can be used. If there are exactly the number of conditions as index columns, then the hash index might be used. By default (for equal, greaterThan, lessThan, greaterEqual, lessEqual) there is one condition. AndPredicateImpl overrides this method.
