Method Detail

getVariable

ISymbol getVariable(java.lang.String name)
Gets the most appropriate symbol in the current context based on name. Most "appropriate" may take into account scoping and other rules.

Parameters:
name -
Returns:
a symbol

getAllVariables

ISymbol[] getAllVariables()
Returns:
all valid symbols in the current context

getProperty

ISymbol getProperty(
ISymbol symbol,
                    java.lang.Object propertyName)
Parameters:
symbol -
propertyName -
Returns:
the property symbol called propertyName or null if not found

getProperties

ISymbol[] getProperties(
ISymbol symbol)
Parameters:
symbol -
Returns:
all properties of symbol

getMethod

IMethodSymbol getMethod(
IObjectSymbol base,
                        java.lang.Object methodName)
Parameters:
base -
methodName -
Returns:
the method of base matching methodName or null if not found

getMethods

ISymbol[] getMethods(
IObjectSymbol base)
Parameters:
base -
Returns:
all methods belonging to base

hasSameResolution

boolean hasSameResolution(
IModelContext modelContext)
This is meant to be used things like caching to determine if caches need to be flushed for different contexts. If you are in doubt, always return false. NOTE: this method should not be used to determine if symbols previously returned by this resolver have changed to do changes in the underlying application such as change to a managed bean. This method only needs to check if what variable, properties and methods may have resolved different, because of the context itself.

Parameters:
modelContext -
Returns:
true if the instance of this resolver would resolve everything exactly the same with this modelContext. False otherwise.
Since:
3.0
