Class IdInExpression

java.lang.Object

com.avaje.ebeaninternal.server.expression.IdInExpression

All Implemented Interfaces:

Expression, SpiExpression, Serializable

public class IdInExpression
extends Object
implements SpiExpression

Slightly redundant as Query.setId() ultimately also does the same job.

Method Detail

containsMany

public void containsMany(BeanDescriptor<?> desc,
                ManyWhereJoins manyWhereJoin)

Description copied from interface: SpiExpression

Process "Many" properties populating ManyWhereJoins.

Predicates on Many properties require an extra independent join clause.

Specified by:

containsMany in interface SpiExpression

addBindValues

public void addBindValues(SpiExpressionRequest request)

Description copied from interface: SpiExpression

Add the parameter values to be set against query. For each ? place holder there should be a corresponding value that is added to the bindList.

Specified by:

addBindValues in interface SpiExpression

Parameters:

request - the associated request.

addSqlNoAlias

public void addSqlNoAlias(SpiExpressionRequest request)

For use with deleting non attached detail beans during stateless update.

addSql

public void addSql(SpiExpressionRequest request)

Description copied from interface: SpiExpression

Add some sql to the query.

This will contain ? as a place holder for each associated bind values.

The 'sql' added to the query can contain object property names rather than db tables and columns. This 'sql' is later parsed converting the logical property names to their full database column names.

Specified by:

addSql in interface SpiExpression

Parameters:

request - the associated request.

queryAutoFetchHash

public void queryAutoFetchHash(HashQueryPlanBuilder builder)

Incorporates the number of Id values to bind.

Specified by:

queryAutoFetchHash in interface SpiExpression

queryPlanHash

public void queryPlanHash(BeanQueryRequest<?> request,
                 HashQueryPlanBuilder builder)

Description copied from interface: SpiExpression

Calculate a hash value for the expression. This includes the expression type and property but should exclude the bind values.

This is used where queries are the same except for the bind values, in which case the query execution plan can be reused.

Specified by:

queryPlanHash in interface SpiExpression

queryBindHash

public int queryBindHash()

Description copied from interface: SpiExpression

Return the hash value for the values that will be bound.

Specified by:

queryBindHash in interface SpiExpression
