.
The ELContext
maintains a collection of context objects relevant to the evaluation of an expression.
These context objects are used by ELResolver
s. 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.
