type - the resource type

add

public void add(Resource resource,
                ResourceType type,
                ResourceConfiguration configuration)

Description copied from interface: KnowledgeBuilder

Add a resource of the given ResourceType, using the provided ResourceConfiguration. Resources can be created by calling any of the "newX" factory methods of ResourceFactory. The kind of resource (DRL, XDRL, DSL,... CHANGE_SET) must be indicated by the second argument.

Specified by:

add in interface KnowledgeBuilder

Parameters:

resource - the Resource to add

type - the resource type

configuration - the resource configuration

getKnowledgePackages

public Collection<KnowledgePackage> getKnowledgePackages()

Description copied from interface: KnowledgeBuilder

Returns the built packages. If the KnowledgeBuilder has errors the Collection will be empty. The hasErrors() method should always be checked first, to make sure you are getting the packages that you wanted built.

Specified by:

getKnowledgePackages in interface KnowledgeBuilder

Returns:

The Collection of KnowledgePackages

newKnowledgeBase

public KnowledgeBase newKnowledgeBase()

Description copied from interface: KnowledgeBuilder

Creates a new KnowledgeBase from the knowledge packages that have been added to this builder. An exception is thrown if there are any errors.

Specified by:

newKnowledgeBase in interface KnowledgeBuilder

hasErrors

public boolean hasErrors()

Description copied from interface: KnowledgeBuilder

If errors occurred during the build process they are added here

Specified by:

hasErrors in interface KnowledgeBuilder

Returns:

getErrors

public KnowledgeBuilderErrors getErrors()

Description copied from interface: KnowledgeBuilder

Return errors that occurred during the build process.

Specified by:

getErrors in interface KnowledgeBuilder

Returns:

getResults

public KnowledgeBuilderResults getResults(ResultSeverity... severities)

Description copied from interface: KnowledgeBuilder

Return the knowledge builder results for the listed severities.

Specified by:

getResults in interface KnowledgeBuilder

Returns:

hasResults

public boolean hasResults(ResultSeverity... severities)

Description copied from interface: KnowledgeBuilder

Checks if the builder generated any results of the listed severities

Specified by:
