Interoperability bridge for application hosts

A system for function call invocation, the system comprising:

• a processor, and
• a memory storing computer-executable instructions that when executed by the processor cause the system to:
• generate, by a host bridge based on a schema, first and second functions of an application bridge interface implemented in a first programming language and executed within an application host, wherein the schema defines the first function for communicating data between a first user application and a reusable bridge module of the host bridge, wherein the schema defines the second function for communicating data between a second user application and the reusable bridge module;
• generate, by the host bridge based on the schema, third and fourth functions of a native bridge interface implemented in a second programming language and executed within a native host, wherein the first programming language is different from the second programming language, wherein the schema defines the third function for communicating data between the bridge module and a first native function of the native host, wherein the schema defines the fourth function for communicating data between the reusable bridge module and a second native function of the native host;
• receive, from the first user application via the application bridge interface, a function call to the first function that corresponds to the third function and wherein the first user application is executed within the application host in the first programming language;
• generate, by the reusable bridge module of the host bridge, a first common data structure based at least in part on the function call to the first function;
• and
• send, by the reusable bridge module of the host bridge, the first common data structure to the third function of the native bridge interface, wherein the third function converts the first common data structure to a first native data structure implemented in the second programming language, and calls the first native function within the native host using the first native data structure;
• receive, from the second user application via the application bridge interface, a function call to the second function that corresponds to the fourth function, wherein the second user application is executed within the application host in the first programming language;
• generate, by the reusable bridge module of the host bridge, a second common data structure based at least in part on the function call to the second function;
• and
• send, by the reusable bridge module of the host bridge, the second common data structure to the fourth function of the native bridge interface, wherein the fourth function converts the second common data structure to a second native data structure implemented in the second programming language and calls the second native function within the native host using the second native data structure.

A method for event processing, the method comprising:

• processing, by a host bridge, a schema that identifies a first event within a native host, and identifies a first event handler function within a first user application that is configured to handle the first event within an application host for a first programming language, the schema further identifying a second event within the native host, and further identifying a second event handler function within a second user application that is configured to handle the second event within the application host;
• generating, by the host bridge and based on the schema, a first function of an application bridge interface that is implemented in a first programming language, executed within the application host, and communicates between the user application and a reusable bridge module of the host bridge;
• generating, by the host bridge and based on the schema, a second function of the application bridge interface that is implemented in the first programming language, executed within the application host, and communicates between the second user application and the reusable bridge module of the host bridge;
• generating, by the host bridge and based on the schema, a third function of a native bridge interface that is implemented in a second programming language, executed within the native host, communicates between the reusable bridge module and the native host, and includes a first event receiver function for the first event, wherein the first programming language is different from the second programming language;
• generating, by the host bridge and based on the schema, a third function of the native bridge interface that is implemented in the second programming language, executed within the native host, communicates between the reusable bridge module and the native host, and includes a second event receiver function for the second event;
• receiving, by the host bridge via the native bridge interface, a call to the first event receiver function from the native host;
• generating, by the host bridge via the first event receiver function of the native bridge interface, a first common data structure that corresponds to the first event based at least in part on the call to the first event receiver function;
• converting, by the host bridge via the application bridge interface, the first common data structure to a first application data structure implemented in the first programming language;
• and
• calling, by the host bridge via the first function of the application bridge interface, the first event handler function within the application host using the first application data structure;
• receiving, by the host bridge via the native bridge interface, a call to the second event receiver function from the native host;
• generating, by the host bridge via the second event receiver function of the native bridge interface, a second common data structure that corresponds to the second event based at least in part on the call to the second event receiver function;
• converting, by the host bridge via the application bridge interface, the second common data structure to a second application data structure implemented in the first programming language;
• and
• calling, by the host bridge via the second function of the application bridge interface, the second event handler function within the application host using the second application data structure.
