Detailed Description

A progress report that immediately claims it is finished.

There is no need to call setFinished(); this will be done automatically by the constructor.

Python:
Not present; all progress classes communicate with external interfaces through the NProgress interface.
Deprecated:
This class is deprecated. Please use the more flexible and more streamlined NProgressTracker class instead.

Constructor & Destructor Documentation

regina::NProgressFinished::NProgressFinished ( )
inline

Creates a new finished progress report.

This constructor will automatically call setFinished().

Member Function Documentation

std::string regina::NProgressFinished::internalGetDescription ( ) const
inlineprotectedvirtual

Returns a string description of the current state of progress.

This function must not touch the mutex, and is not required to alter the changed flag. The getDescription() routine takes care of all of these issues.

Precondition
The mutex is currently locked.
Returns
the current state of progress.

Implements regina::NProgress.

double regina::NProgressFinished::internalGetPercent ( ) const
inlineprotectedvirtual

Returns the current state of progress as a percentage.

The default implementation returns 0.

This function must not touch the mutex, and is not required to alter the changed flag. The getDescription() routine takes care of all of these issues.

Precondition
Progress can be expressed as a percentage (see isPercent()).
The mutex is currently locked.
Returns
the current state of progress as a percentage.

Reimplemented from regina::NProgress.

bool regina::NProgressFinished::isPercent ( ) const
inlinevirtual

Determines if the state of progress can be expressed as a percentage.

The default implementation returns false.

Returns
true if and only if progress can be expressed as a percentage.

Reimplemented from regina::NProgress.
