GP Task
- URL:https://<gpservice-url>/<taskName>
- Operations:Execute Task, Submit Job
- Child Resources:Job
- Version Introduced:9.3
Description
The GP Task resource represents a single task in a geoprocessing service published using ArcGIS Server. It provides basic information about the task including its name and display name. It also provides detailed information about the various input and output parameters exposed by the task.
GP Task supports the following two operations:
- submitJob—Use for asynchronous tasks. Asynchronous means that your application does not wait for the task to finish execution, and the end user can continue using the application.
- execute—Use for synchronous tasks. Synchronous means that the application waits while the tool executes on the server. Because the end user must wait, you should determine whether the wait time is acceptable for the type of application.
