Method Details

getCallingContextTree

public Collection<AggregatedCallSite> getCallingContextTree(ICallStackElement element)

Gets the calling context tree for an element. The calling context tree is the callgraph data aggregated by keeping the context of each call.

Parameters:

element - The element for which to get the calling context tree

Returns:

The aggregated data for the first level of the callgraph

addAggregatedCallSite

public void addAggregatedCallSite(ICallStackElement dstGroup,
 AggregatedCallSite callsite)

Add an aggregated callsite toa callstack element.

Parameters:

dstGroup - the destination group

callsite - the callsite to add

getElements

public Collection<ICallStackElement> getElements()

Get the root elements containing the call graph data.

Specified by:

getElements in interface IWeightedTreeSet<@NonNull ICallStackSymbol,ICallStackElement,AggregatedCallSite>

Returns:

The root elements of the call graph

getTreesFor

public Collection<AggregatedCallSite> getTreesFor(Object element)

Description copied from interface: IWeightedTreeSet

Get the weighted trees for a given element

Specified by:

getTreesFor in interface IWeightedTreeSet<@NonNull ICallStackSymbol,ICallStackElement,AggregatedCallSite>

Parameters:

element - The element for which to get the trees

Returns:

A collection of weighted trees for the requested element
