Constructor Detail

JDBCQuery

public JDBCQuery(com.solarmetric.rd.kodo.impl.jdbc.runtime.JDBCStoreManager store,
                 java.lang.Object copy)

Constructor.

Parameters:

store - the store manager

copy - a compiled query to copy configuration from, or null

Method Detail

getUseSQL92Joins

public boolean getUseSQL92Joins()

Return whether to use SQL 92-style joins for this query. Defaults to the setting of the com.solarmetric.kodo.impl.jdbc.UseSQL92Joins configuration property.

setUseSQL92Joins

public void setUseSQL92Joins(boolean useJoins)

Set whether to use SQL 92-style joins for this query. Defaults to the setting of the com.solarmetric.kodo.impl.jdbc.UseSQL92Joins configuration property.

executeQuery

protected com.solarmetric.rd.rop.ResultList executeQuery(com.solarmetric.rd.kodo.meta.ClassMetaData meta,
                                                         boolean subclasses,
                                                         com.solarmetric.rd.kodo.query.ExpressionFactory factory,
                                                         com.solarmetric.rd.kodo.query.Expression exp,
                                                         java.util.Map params)

Description copied from class: QueryImpl

Execute the given expression against the given candidate extent.

Specified by:

executeQuery in class QueryImpl

Parameters:

meta - the base type the query should match

subclasses - true if subclasses should be included in the results

factory - the expression factory used to compile the expression

exp - the compiled expression for the parsed query

params - map of parameter names to values

Returns:

a list of matching objects

getExpressionFactory

protected com.solarmetric.rd.kodo.query.ExpressionFactory getExpressionFactory(com.solarmetric.rd.kodo.meta.ClassMetaData meta)

Description copied from class: QueryImpl

Return an ExpressionFactory to use to create an expression to be executed against an extent. Each factory will be used to compile one filter only.

Specified by:

getExpressionFactory in class QueryImpl

getStandardFilterListener

protected com.solarmetric.rd.kodo.query.FilterListener getStandardFilterListener(java.lang.String tag)

Description copied from class: QueryImpl

Return the standard filter extension for the given tag, or null if none. This method is called only after checking the listeners that have been added to this particular query and the user-defined listeners in the com.solarmetric.kodo.conf.JDOConfiguration.

Specified by:

getStandardFilterListener in class QueryImpl
