Context Reset Service

Version History

Overview

ContextReset allows to execute reset commands on the taget. The exact behavior of reset command depends on the taget.

Clients can use getCapabilities command to learn about available reset types.

The service uses standard format for error reports, see Error Report Format.

Commands

Get Capabilities

C • <token> • ContextReset • getCapabilities • <string: context ID> •

The command reports reset service capabilities to clients so they can adjust to different implementations of the service. When called with a null ("") context ID the global capabilities are returned, otherwise context specific capabilities are returned.

Reply:

R • <token> • <error report> • <service capabilities> •

<service capabilities>
    ⇒ <object>

Service capabilities consist of a list of properties. All properties are optional. Tools and targets can define additional properties.

Reset

C • <token> • ContextReset • reset • <string: context ID> • <string: reset type> • <reset parameters> •

<reset parameters>
    ⇒ <object>

The command performs reset of a specified context.

Reset parametes are optional. Tools and targets can define additional properties.

Predefined parameters are:

• "Suspend" : <boolean>
  If true, context gets suspended after reset.

Reply:

R • <token> • <error report> •
