Class: TPicoseconds

Declaration: TimeClasses.h

Taxonomy Categories:

Member Functions:

Interface Category:

API.

Inherits From:

TTime

Inherited By:

None.

Purpose:

A picoseconds derived class of TTime.

Instantiation:

Allocate on the heap or the stack.

Deriving Classes:

Derived classes must preserve the picoseconds representation and TTime interfaces.

Concurrency:

Not multithread safe.

Resource Use:

No special requirements.

Member Function: TPicoseconds::TPicoseconds

TPicoseconds ()
TPicoseconds (double numberOfPicoseconds)
TPicoseconds (const TPicoseconds & thePicoseconds)
TPicoseconds (const TTime & theTime)

Interface Category:

API.

Purpose:

Default constructor.
Constructor initializing the number of picoseconds.
Copy constructor.
Constructor for the base class.

Calling Context:

Call this function directly. Call this function directly.

Called by the stream-in operators and for uninitialized objects.
Called to initialize an object with a value.
Called to copy an object.
Called to copy any TTime derived class.

Parameters:

Takes no parameters.
double numberOfPicoseconds -The number of picoseconds the object represents.
const TPicoseconds & thePicoseconds -The object to copy.
const TTime & theTime -The object to copy.

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

Can be safely type cast between TTime derived classes because no extra storage is added.

Member Function: TPicoseconds::~TPicoseconds

virtual ~ TPicoseconds ()

Interface Category:

API.

Purpose:

Destructor.

Calling Context:

Call this function directly. Called to destroy an object.

Parameters:

Takes no parameters.

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

None.

Member Function: TPicoseconds::GetPicoseconds

double GetPicoseconds () const

Interface Category:

API.

Purpose:

Gets the number of picoseconds represented by the object.

Calling Context:

Call this function directly. Called to get the picoseconds in a double.

Parameters:

Takes no parameters.

Return Value:

The picoseconds in the object.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

Returns a double that could be a NaN, or positive or negative infinity, depending on the time.

Member Function: TPicoseconds::operator=

TPicoseconds & operator =(const TPicoseconds & thePicoseconds)

Interface Category:

API.

Purpose:

Assignment operator.

Calling Context:

Call this function directly. Called when an object is assigned to another compatible object.

Parameters:

const TPicoseconds & thePicoseconds -The object to assign.

Return Value:

A non-const reference to the left-hand side object.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

None.
