Method Detail

setOffset

Query<T> setOffset(java.lang.Long offset)

Add offset and chunkSize for the search

setChunkSize

Query<T> setChunkSize(java.lang.Long chunkSize)

orderBy

                 java.lang.Boolean ascending)

Use this method to set the Map of element that must be considered for ordering Attach for each field a Boolean.TRUE for ascending a boolean.FALSE for descending ordering

and

Query<T> and(Attribute element,
             java.lang.Boolean ascending)

where

Query<T> where(SearchExpression elm)

Add QueryExpressions for the search

and

Query<T> and(SearchExpression elm)

exist

<P extends BusinessObject> Query<T> exist(Query<P> subQuery,
                                          ForeignKeyAttribute element)

Combining the query with a subquery. The attribute must be a ForeignKey of the main query. It is used for field-comparison with the id of the subquery

Parameters:

subQuery -

element -

exist

<P extends BusinessObject> Query<T> exist(Query<P> subQuery,
                                          ForeignKeyAttribute elementMainQuery,
                                          ForeignKeyAttribute elementSubQuery)

Combining the query with a subquery. The given attributes are used for field-comparison. Notice that both fields must be of type ForeignKeyAttribute

Parameters:

subQuery -

elementMainQuery -

elementSubQuery -

Returns:
