active:unlock

Argument	Rules	Description
operand	Mandatory	the resource to be unlocked

Example Usage

DPML

<instr>
  <type>unlock</type>
  <operand>file:/inventory.xml</operand>
</instr>

NetKernel Foundation API

req=context.createSubRequest("active:unlock");
req.addArgument("operand", [resource representation, aspect, or URI] );
result=context.issueSubRequest(req);

Purpose

The unlock accessor is used to release a lock place on a name resource with the lock accessor. When a resource is locked, the current request gains exclusive use of the resource and stops other processes from gaining access until the lock is released. A second request to lock a resource will block indefinitely until the previous lock is released with the unlock accessor.
