Description copied from interface: ConcurrentOperationMap

The operation will be keyed on the name .

Specified by:

runOperation in interface ConcurrentOperationMap

Parameters:

key - the key, like any map key this should be an immutable object that correctly implements #hashCode() and #equals(Object)

operation - is the operation to execute whose result will be accessible to any concurrent callers with the same key.

Returns:

result of the operation

Throws:

edu.emory.mathcs.backport.java.util.concurrent.ExecutionException - if the callable generated a checked exception, otherwise a runtime exception or error will be thrown
