Class CachingSymbolContextResolver
java.lang.Object
org.eclipse.jst.jsf.designtime.resolver.AbstractSymbolContextResolver
org.eclipse.jst.jsf.designtime.resolver.CachingSymbolContextResolver

All Implemented Interfaces:
-
IContextResolver,
IDocumentContextResolver,
ISymbolContextResolver
-
public final class CachingSymbolContextResolver
- extends
AbstractSymbolContextResolver
A symbol resolver that delegates to the default SymbolContextResolver, but
caches the results and returns those on subsequent calls.
WARNING: this resolver is suitable *only* in situations where the state
of dependent symbol sources won't change between calls. This resolver makes
no attempt to ensure that cached data is in sync with changes to symbols
such addition, modification or removal of Java class underlying beans.
NOTE: this resolver is experimental and should NOT be considered API
Clients should not use this resolver directly. Access it through the factory instead

-
Description copied from interface:
ISymbolContextResolver
- Gets the most appropriate symbol in the current context
based on name. Most "appropriate" may take into account
scoping and other rules.

hasSameResolution
public boolean hasSameResolution(
IModelContext modelContext)
-
Description copied from class:
AbstractSymbolContextResolver
- Default implementation
We should avoid returning true unless we are positive that changing
to this context won't change the way symbols are resolved.

-
Specified by:
-
hasSameResolution
in interface
ISymbolContextResolver
-
Overrides:
-
hasSameResolution
in class
AbstractSymbolContextResolver
-
-
Returns:
- true if the instance of this resolver would resolve everything
exactly the same with this modelContext. False otherwise.
