Method Detail

loadContext

public Context loadContext(SelectionCriteria selectionCriteria,
                           Map<Term,Object> facts,
                           ExecutionOptions executionOptions)

Description copied from interface: ContextProvider

Loads the context for the given selection criteria, facts, and execution options. If no context can be located based on the given criteria, then this method should return null.

In the case where multiple Contexts could potentially be identified from the same set of selection criteria, it is up to the implementer of the ContextProvider to ensure that the most appropriate Context is returned. Or alternatively, an exception could be thrown indicating context ambiguity.

The sectionCriteria, facts, and executionOptions which are passed to this method should never be null. However, they might be empty.

Specified by:

loadContext in interface ContextProvider

Parameters:

selectionCriteria - the criteria to use during the selection phase of engine operation

facts - the set of facts that are supplied to the engine at execution time

executionOptions - a collection of options that can be used to customize engine execution behavior

Returns:

the context which matches the given criteria, or null if no context matches
