US 2004/0025147 A1 · Mixed language expression loading and execution methods and apparatuses

Abstract

A mixed language expression execution method and apparatus includes an execution engine equipped to determine whether an execution context has previously been created for an expression, upon receiving a request to execute the expression. If not, one is created, invoking one or more expression processors, to contribute to the initialization of the execution context. If created or upon creation, the expression (including its sub-expressions, if any) is executed, using the execution context. The result is then returned to the requester. In one embodiment, the execution context is object oriented, and includes various methods to facilitate the initialization and execution. Further, at least one expression processor includes a load and an execute interface equipped to use these methods.

Dependent claims

A computing environment comprising:

a first expression processor to load an expression/sub-expression of a first expression language;
a second expression processor to load an expression/sub-expression of a second expression language;
and
an execution engine operationally coupled to the first and second expression processors to facilitate the first and second expression processors to cooperate to load an expression of the first expression language having at least a sub-expression of the second expression language.
