public java.lang.Object getContext(java.lang.Class key)
ELContextThe ELContext maintains a collection of context objects
relevant to the evaluation of an expression. These context objects
are used by ELResolvers. This method is used to
retrieve the context with the given key from the collection.
By convention, the object returned will be of the type specified by
the key. However, this is not required and the key is
used strictly as a unique identifier.
getContext in class ELContextkey - The unique identifier that was used to associate the
context object with this ELContext.
public ELResolver getELResolver()
ELContextELResolver associated with this context.
The ELContext maintains a reference to the
ELResolver that will be consulted to resolve variables
and properties during an expression evaluation. This method
retrieves the reference to the resolver.
Once an ELContext is constructed, the reference to the
ELResolver associated with the context cannot be changed.
getELResolver in class ELContextpublic boolean isPropertyResolved()
ELContextELResolver has successfully resolved a
given (base, property) pair.
The CompositeELResolver checks this property to determine
whether it should consider or skip other component resolvers.

ELContextELContext.
The ELContext maintains a collection of context objects
relevant to the evaluation of an expression. These context objects
are used by ELResolvers. This method is used to
add a context object to that collection.
By convention, the contextObject will be of the
type specified by the key. However, this is not
required and the key is used strictly as a unique identifier.
putContext in class ELContextkey - The key used by an @{link ELResolver} to identify this
context object.contextObject - The context object to add to the collection.public void setPropertyResolved(boolean resolved)
ELContextELResolver has successfully
resolved a given (base, property) pair.
The CompositeELResolver checks this property to determine
whether it should consider or skip other component resolvers.
setPropertyResolved in class ELContextresolved - true if the property has been resolved, or false if
not.CompositeELResolverpublic void clearResolvedProperties()
