Program, information processing apparatus, and event processing method

An event processing apparatus comprising:

• a memory configured to store rule information that includes information indicating a plurality of operations that is started according to types of events indicated in event data;
• and
• a processor configured to perform a process including:
• searching the rule information to find information indicating a first operation that is started for event data of a first type, information indicating an operation of a condition determination that is executable using the event data regardless of a result of the first operation and that is started after the first operation is executed, and information indicating a second operation whose execution is determined depending on a result of the condition determination and which uses the result of the first operation,
• generating, for the first type, control information for controlling an execution order of the operations such that execution of the first operation is determined depending on a result of the condition determination and such that the second operation is started after the first operation is executed, and
• executing, when the event data of the first type is input, the operations corresponding to the input event data, based on the control information.

An event processing method comprising:

• searching, by a processor, rule information that includes information indicating a plurality of operations that is started according to types of events indicated in event data, to find information indicating a first operation that is started for event data of a first type, information indicating an operation of a condition determination that is executable using the event data regardless of a result of the first operation and that is started after the first operation is executed, and information indicating a second operation whose execution is determined depending on a result of the condition determination and which uses the result of the first operation,
• generating, by the processor, for the first type, control information for controlling an execution order of the operations such that execution of the first operation is determined depending on a result of the condition determination and such that the second operation is started after the first operation is executed;
• and
• executing, by the processor, when the event data of the first type is input, the operations corresponding to the input event data, based on the control information.
