Detailed Description

A PlotAxesStack is basically a list of PlotRegions as well as axis information that provides stack functionality such as a current index, and moving up and down the stack.

A valid stack has a "base" followed by zero or more PlotRegions. A stack can optionally have a limit on its length; adding to the stack after it reaches its length will remove the oldest members after the base. The smallest value this limit can be is 2, (base + 1 value).

Constructor & Destructor Documentation

casa::PlotAxesStack::PlotAxesStack ( int lengthLimit = -1 )

Constructor for empty stack.

Length limits with values <= 1 mean no limit.

casa::PlotAxesStack::~PlotAxesStack ( )

Destructor.

Member Function Documentation

void casa::PlotAxesStack::addRegion	(	const PlotRegion &	region,
		PlotAxis	xAxis,
		PlotAxis	yAxis
	)

Adds the given region to the stack.

void casa::PlotAxesStack::clearLengthLimit ( )

inline

Definition at line 749 of file PlotOptions.h.

References setLengthLimit().

void casa::PlotAxesStack::clearStack ( bool keepBase = false )

Clears the stack, including the base if keepBase is false.

PlotRegion casa::PlotAxesStack::currentRegion ( ) const

Returns the current region in the stack.

PlotAxis casa::PlotAxesStack::currentXAxis ( ) const

Returns the x-axis for the current region in the stack.

PlotAxis casa::PlotAxesStack::currentYAxis ( ) const

Returns the y-axis for the current region in the stack.

bool casa::PlotAxesStack::isValid ( ) const

Returns whether the stack is valid (has size > 0) or not.

int casa::PlotAxesStack::lengthLimit ( ) const

Gets/Sets the length limit on this stack.

Values <= 1 mean no limit.

void casa::PlotAxesStack::move ( int delta )

Moves the stack index the given delta.

If delta is negative, the index goes backwards; if delta is positive, the index goes forward. If delta is zero, the index goes to the base.

PlotRegion casa::PlotAxesStack::moveAndReturn ( int delta )

Moves the stack index the given delta (see move()) and returns the current region.

void casa::PlotAxesStack::setBase	(	const PlotRegion &	base,
		PlotAxis	xAxis,
		PlotAxis	yAxis
	)

Resets the stack and sets the stack base to the given.

void casa::PlotAxesStack::setLengthLimit ( int lengthLimit )

Referenced by clearLengthLimit().

void casa::PlotAxesStack::shrinkStacks ( unsigned int n )

private

Shrinks the region and axes stack to the given size, discarding the oldest UNLESS the stack index is in the elements to be discarded.

In this case, the element referenced by the index is also kept.

unsigned int casa::PlotAxesStack::size ( ) const

Returns the stack size.

std::vector<PlotRegion> casa::PlotAxesStack::stack ( ) const

Returns a copy of the stack.

std::vector<std::pair<PlotAxis, PlotAxis> > casa::PlotAxesStack::stackAxes ( ) const

Returns a copy of the stack axes.

The first item is for x, the second for y.

unsigned int casa::PlotAxesStack::stackIndex ( ) const

Returns the current stack index.
