Detailed Description

This class is a collection of time marks to manage various events occurring during simulation time.

TimeMark and their types

One TimeMark consists of time and type (TimeMark::Type), see the constructor TimeMark::TimeMark. The type of mark is bitmap where individual bits corresponds to some base event types like changing a BC, output solution, coupling time with another equation and so on. Base types can be combined by bitwise or (operator|).

Special types are predefined in TimeMarks class. These are returned by their getters:

TimeMarks collection

TimeMarks collect marks of various types and provides methods for iterating over stored marks. You can selectively access only marks matching given type mask. See TimeMark::match_mask.

You can add one new mark through method add or add evenly spaced marks of same type by TimeMarks::add_time_marks.

You can allocate new TimeMark::Type in the context of one TimeMarks object by TimeMarks::new_mark_type.

For a given TimeGovernor (not necessarily connected one) you can ask about existence of mark in current time interval (TimeMarks::is_current) and see TimeMarks close to the current time (TimeMarks::next and TimeMarks::last). The current time interval is left-open and right-closed: (t,t+dt]. Repeatedly used TimeMarks::next always returns the same TimeMark if the time of the TimeGovernor is not changed.

In most cases there will be only one TimeMarks object for the whole solved problem and used by TimeGovernors of individual equations. However this is not necessary.

Here is the caller graph for this function:

◆ begin() [2/2]

TimeMarks::iterator TimeMarks::begin ( unsigned char  ei) const

Same as previous, but constructs TimeMark::Type from equation index.

Definition at line 199 of file time_marks.cc.

◆ current()

TimeMarks::iterator TimeMarks::current ( const TimeStep time_step,
const TimeMark::Type mask 
) const

Definition at line 183 of file time_marks.cc.

◆ last() [3/3]

TimeMarks::iterator TimeMarks::last ( const TimeStep time_step,
const TimeMark::Type mask 
) const

Return the last TimeMark with time less or equal to tg.time() that match the mask. The time governor tg is used also for time comparisons.

Parameters
tgthe time governor
maskmask of marks to iterate on

Here is the caller graph for this function:

◆ new_mark_type()

TimeMark::Type TimeMarks::new_mark_type ( )

Add a new base mark within the context of the particular TimeMarks instance. User should keep the returned value (MarkType is basically a bitmap) for further queries and TimeMark insertions. ATTENTION: You can not use the TimeMark::Type with other TimeMarks instance! Types are added as they are prepared in next_mark_type_. Next mark type is updated by (left) bit shifting operator.

Definition at line 68 of file time_marks.cc.

Here is the caller graph for this function:

◆ next()

TimeMarks::iterator TimeMarks::next ( const TimeGovernor tg,
const TimeMark::Type mask 
) const

Return the first TimeMark with time strictly greater then tg.time() that match the mask. The time governor tg is used also for time comparisons.

Parameters
tgthe time governor
maskmask of marks to iterate on

TODO: have also method which accepts double (time) instead of the whole TimeGovernor. and compare without safety.
