Constructor Details

AbstractSourceItemTransformer

protected AbstractSourceItemTransformer(Item source,
Item target)

Create a new instance that transforms between the given source and target item types.

Method Details

getSourceItemType

public Item getSourceItemType()

Description copied from interface: SourceItemTransformer

Get the item type of the source items.

Specified by:

getSourceItemType in interface SourceItemTransformer

getTargetItemType

public Item getTargetItemType()

Description copied from interface: SourceItemTransformer

Get the item type of the target items.

Specified by:

getTargetItemType in interface SourceItemTransformer

safeIdList

protected Set<Integer> safeIdList(DbControl dc,
ItemQuery<?> query,
String parameterName,
Set<Integer> values)

Safely execute the query even if the number of values in the 'values' set is higher than DbEngine.getMaxParametersInQuery(). In this case, the values will be divided into subsets and the result of the query is merged in memory. It is important that the query is such that executing it multiple times with different subsets return the same result as if it was only executed a single time with the complete set.

Parameters:

query - The query to execut

parameterName - The name of the parameter to set for the values

values - The values to use in the query

Returns:

The result of the query.idList() method
