Providing access to state information associated with operators in a data processing system

A method for accessing hidden state information from operators within a data processing system, comprising:

• generating state information within an operator of the data processing system based on an input received from a data source;
• generating an output utilizing the operator based on the state information, wherein the state information is not outputted from the operator;
• providing, to the data processing system, a graph query comprising a request to determine the state information of the operator;
• based on the graph query, accessing a node of an object information data structure via an object interface, wherein the node symbolically represents the operator by storing a copy of the state information of the operator, and wherein the object information data structure is a separate data structure from the operator that provides access to the node;
• and
• receiving, from the data processing system, the copy of the state information obtained from the node in the object information data structure.

A system for providing access to hidden state information within operators of a data processing system, comprising:

• a processor;
• and
• a computer memory comprising instructions that, when executed by the processor, cause the system to perform operations comprising:
• generating state information within an operator of the data processing system based on an input received from a data source;
• generating an output utilizing the operator based on the state information, wherein the state information is not included in the output;
• receiving, from a querying entity, a graph query to retrieve the state information from the operator, wherein the state information is not available via querying the operator;
• based on the graph query, accessing a node of an object information data structure via an object interface, wherein the node symbolically represents the operator by storing a copy of the state information of the operator, and wherein the object information data structure is a separate data structure from the operator that provides access to a node;
• and
• providing the copy of the state information from the object information data structure in response to the querying entity.
