void com.mysql.clusterj.core.query.QueryDomainTypeImpl< T >.assertAllParametersBound ( QueryExecutionContext  context )

inlineprotected

Assert that all parameters used by this query are bound.

Parameters

context

the context, including the parameter map

Exceptions

ClusterJUserException

if not all parameters are bound

Definition at line 417 of file QueryDomainTypeImpl.java.

int com.mysql.clusterj.core.query.QueryDomainTypeImpl< T >.deletePersistentAll ( QueryExecutionContext  context )

inline

Delete the instances that satisfy the query and return the number of instances deleted. The type of operation used to find the instances (primary key lookup, unique key lookup, index scan, or table scan) depends on the where clause and the bound parameter values.

Parameters

context

the query context, including the bound parameters

Returns

the number of instances deleted

Exceptions

ClusterJUserException

if not all parameters are bound

Definition at line 283 of file QueryDomainTypeImpl.java.

Here is the call graph for this function:

void com.mysql.clusterj.core.query.QueryDomainTypeImpl< T >.explain ( QueryExecutionContext  context )

inline

Explain how this query will be or was executed and store the result in the context.

Parameters

context

the context, including bound parameters

Definition at line 390 of file QueryDomainTypeImpl.java.

Here is the call graph for this function:

ResultData com.mysql.clusterj.core.query.QueryDomainTypeImpl< T >.getResultData ( QueryExecutionContext  context )

inline

Execute the query and return the result data. The type of operation (primary key lookup, unique key lookup, index scan, or table scan) depends on the where clause and the bound parameter values.

Parameters

context

the query context, including the bound parameters

Returns

the raw result data from the query

Exceptions

ClusterJUserException

if not all parameters are bound

Definition at line 185 of file QueryDomainTypeImpl.java.

Here is the call graph for this function:

List<T> com.mysql.clusterj.core.query.QueryDomainTypeImpl< T >.getResultList ( QueryExecutionContext  context )

inline

Query.getResultList delegates to this method.

Returns

the results of executing the query

Definition at line 147 of file QueryDomainTypeImpl.java.

Here is the call graph for this function:

Map<String, Object> com.mysql.clusterj.core.query.QueryDomainTypeImpl< T >.newExplain ( CandidateIndexImpl  index, ScanType  scanType  )

inlineprotected

Create a new explain for this query.

Parameters

index	the index used
scanType	the scan type

Returns

the explain

Definition at line 405 of file QueryDomainTypeImpl.java.

Predicate com.mysql.clusterj.core.query.QueryDomainTypeImpl< T >.not ( Predicate  predicate )

inline

Convenience method to negate a predicate.

Parameters

predicate

the predicate to negate

Returns

the inverted predicate

Definition at line 139 of file QueryDomainTypeImpl.java.

Here is the call graph for this function:

QueryDefinition<T> com.mysql.clusterj.core.query.QueryDomainTypeImpl< T >.where ( Predicate  predicate )

inline

Set the where clause. Mark parameters used by this query.

Parameters

predicate

the predicate

Returns

the query definition (this)
