org.eclipse.jst.jsf.designtime.resolver
Class AbstractSymbolContextResolver

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

All Implemented Interfaces:: IContextResolver, IDocumentContextResolver, ISymbolContextResolver

Direct Known Subclasses:: CachingSymbolContextResolver

public abstract class AbstractSymbolContextResolver
extends java.lang.Object
implements ISymbolContextResolver
extends java.lang.Object
implements ISymbolContextResolver

An abstract that should sub-classed by clients wishing to implement the ISymbolContextResolver interface

Constructor Summary

AbstractSymbolContextResolver ()


Method Summary

abstract boolean canResolveContext ( IModelContext modelContext)


abstract ISymbol[] getAllVariables ()


abstract IMethodSymbol getMethod ( IObjectSymbol base, java.lang.Object methodName)


abstract ISymbol[] getMethods ( IObjectSymbol base)


abstract ISymbol[] getProperties ( ISymbol symbol)


abstract ISymbol getProperty ( ISymbol symbol, java.lang.Object propertyName)


abstract ISymbol getVariable (java.lang.String name)
          Gets the most appropriate symbol in the current context based on name.

boolean hasSameResolution ( IModelContext modelContext)
          Default implementation We should avoid returning true unless we are positive that changing to this context won't change the way symbols are resolved.

Method Detail

getAllVariables

public abstract 
ISymbol[] getAllVariables()

Specified by:: getAllVariables in interface ISymbolContextResolver

Returns:: all valid symbols in the current context

getMethod

public abstract 
IMethodSymbol getMethod(
IObjectSymbol base,
                                        java.lang.Object methodName)

Specified by:: getMethod in interface ISymbolContextResolver

Returns:: the method of base matching methodName or null if not found

getMethods

public abstract 
ISymbol[] getMethods(
IObjectSymbol base)

Specified by:: getMethods in interface ISymbolContextResolver

Returns:: all methods belonging to base

getProperties

public abstract 
ISymbol[] getProperties(
ISymbol symbol)

Specified by:: getProperties in interface ISymbolContextResolver

Returns:: all properties of symbol

getProperty

public abstract 
ISymbol getProperty(
ISymbol symbol,
                                    java.lang.Object propertyName)

Specified by:: getProperty in interface ISymbolContextResolver

Returns:: the property symbol called propertyName or null if not found

getVariable

public abstract 
ISymbol getVariable(java.lang.String name)

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.

Specified by:: getVariable in interface ISymbolContextResolver

Returns:: a symbol

canResolveContext

public abstract boolean canResolveContext(
IModelContext modelContext)

Specified by:: canResolveContext in interface IContextResolver

Returns:: true if this resolver can resolve context information based on this context

hasSameResolution

public boolean hasSameResolution(
IModelContext modelContext)

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

Returns:: true if the instance of this resolver would resolve everything exactly the same with this modelContext. False otherwise.
