Constructor Detail

StacktraceTreeModel

public StacktraceTreeModel(IItemCollection items)

Builds a StacktraceTreeModel from a given collection of events with defaults: frame separator METHOD, the thread root at the top and no value attribute (uses counts).

Parameters:

items - the data we want to represent.

StacktraceTreeModel

public StacktraceTreeModel(IItemCollection items,
                           FrameSeparator frameSeparator)

Builds a StacktraceTreeModel from a given collection of events with defaults: the thread root at the top and no value attribute (uses counts).

Parameters:

items - the data we want to represent.

frameSeparator - defines what represents a node in the tree. Defaults to METHOD.

StacktraceTreeModel

public StacktraceTreeModel(IItemCollection items,
                           FrameSeparator frameSeparator,
                           boolean invertedStacks)

Builds a StacktraceTreeModel from a given collection of events with no attribute specified (uses occurrences to determine node weight).

Parameters:

items - the data we want to represent.

frameSeparator - defines what represents a node in the tree. Defaults to METHOD.

invertedStacks - defines how the stacks are aggregated. Defaults to false (i.e. bottom-up, Thread.run() at the root of the tree).

StacktraceTreeModel

public StacktraceTreeModel(IItemCollection items,
                           FrameSeparator frameSeparator,
                           boolean invertedStacks,
                           IAttribute<IQuantity> attribute)

Builds a StacktraceTreeModel from a given collection of events.

Parameters:

items - the data we want to represent.

frameSeparator - defines what represents a node in the tree. Defaults to METHOD.

invertedStacks - defines how the stacks are aggregated. Defaults to false (i.e. bottom-up, Thread.run() at the root of the tree).

attribute - defines what we use as node weights. If null, the weight is the number of occurrences for the frame.
