Detailed Description

Base class for interrupters.

The host application calls start() at the beginning of an interruptible operation, end() at the end of the operation, and wasInterrupted() periodically during the operation. If any call to wasInterrupted() returns true, the operation will be aborted.

Note
This interrupter was not virtual in a previous implementation, so it could be compiled out, however it remains important to not call wasInterrupter() too frequently so as to balance performance and the ability to interrupt an operation.

Signal the end of an interruptible operation.

virtual NullInterrupter& interrupter ( )
inlinefinalvirtual

Convenience method to return a reference to the base class from a derived class.

virtual void start ( const char *  name = nullptr)
inlinevirtual

Signal the start of an interruptible operation.

Parameters
namean optional descriptive name for the operation
virtual bool wasInterrupted ( int  percent = -1)
inlinevirtual

Check if an interruptible operation should be aborted.

Parameters
percentan optional (when >= 0) percentage indicating the fraction of the operation that has been completed
Note
this method is assumed to be thread-safe.
