Detailed Description

Interface to a particular table of values.

An ITable is a list of number pairs (x,y), which may or may not be ordered by increasing x.
Certain functions will only produce valid results if the table is sorted.

Member Function Documentation

getAll()

virtual QVector<DVect2> itasca::ITable::getAll ( ) const

pure virtual

Assumes pv is the beginning of an array of pass_dvects of length len.
Fills the array with all of its entries (or len, if smaller).

getNotice()

virtual uint itasca::ITable::getNotice ( ) const

pure virtual

Returns a NoticeManager ID that is unique to this table.
This id is returned to the NoticeManager when the table is destroyed.
The NoticeManager is tagged with this ID when the contents of the table are changed in any way.

getSlope()

virtual double itasca::ITable::getSlope ( const double &  x ) const

pure virtual

Returns the slope at position x. Assumes table is sorted.
No higher order operations. Just the slope of the segment bordering x.
Returns 0.0 if x falls outside table extent.

getValue()

virtual double itasca::ITable::getValue ( const double &  x ) const

pure virtual

Returns a Y value associated with X value. Assumes table is sorted.
Does linear interpolation between pairs.
If x is less than the first entry returns first entry y. Similar if x greater than the last entry.

insert()

virtual void itasca::ITable::insert ( const DVect2 &  v )

pure virtual

Inserts value (v.x,v.y) into table based on x value.
Replaces entry if v.x matches existing value. Assumes table is sorted.

put()

virtual void itasca::ITable::put ( int  pos, const DVect2 &  v  )

pure virtual

Places (v.x,v.y) pair at position pos.
Entries are created if pos is larger than current size.
