Constructor Detail

SimpleRoleScope

public SimpleRoleScope(SNode node,
                       SContainmentLink link,
                       SAbstractConcept concept)

SimpleRoleScope

public SimpleRoleScope(SNode node,
                       SContainmentLink link)

Method Detail

resolve

public SNode resolve(SNode contextNode,
                     @NotNull
                     String refText)

Description copied from class: Scope

Resolves element by reference text. Invariant: getReferenceText(contextNode, resolve(contextNode, refText)) == refText

Specified by:

resolve in class Scope

Parameters:

contextNode - source node for the reference, or its nearest parent node (if source node is unavailable)

refText - reference text

Returns:

resolved element when reference text unambiguously identifies element, null otherwise

getAvailableElements

public Iterable<SNode> getAvailableElements(@Nullable
                                            String prefix)

Description copied from class: Scope

Returns all available elements in the scope.

Specified by:

getAvailableElements in class Scope

Parameters:

prefix - (if not null) filters out elements whose reference text doesn't start with prefix

Returns:

list of nodes in the scope

getReferenceText

public String getReferenceText(SNode contextNode,
                               SNode node)

Description copied from class: Scope

Creates textual reference for scope element. If element has no textual representation for the reference, returns null. Invariant: resolve(contextNode, getReferenceText(contextNode, node)) == node

Specified by:

getReferenceText in class Scope

Parameters:

contextNode - source node for the reference, or its nearest parent node (if source node is unavailable)

node - element from the current scope (contains(node) == true)

Returns:

reference text for the node element in the current scope

getName

public abstract String getName(SNode child)

forNamedElements

public static SimpleRoleScope forNamedElements(SNode node,
                                               SContainmentLink linkDeclaration)
