Method Detail

buildEncapsulationTree

public static ITreeNode<org.openjdk.jmc.common.item.IItem> buildEncapsulationTree(org.openjdk.jmc.common.item.IItemCollection items,
                                                                                  boolean allowInstants)

Builds a tree where events that wrap other events, time wise, are higher up in the hierarchy.

Parameters:

items - the items to build a tree from

allowInstants - true to allow instant events in the resulting tree

Returns:

the root node for the resulting tree

buildEncapsulationTree

public static ITreeNode<org.openjdk.jmc.common.item.IItem> buildEncapsulationTree(org.openjdk.jmc.common.item.IItemCollection items,
                                                                                  boolean allowInstants,
                                                                                  boolean ignoreThread)

Builds a tree where events that wrap other events, time wise, are higher up in the hierarchy.

Parameters:

items - the items to build a tree from

allowInstants - true to allow instant events in the resulting tree

ignoreThread - true to make the algorithm not care about event thread, can be used for VM level events. It's up to the caller to make sure this is safe to do.

Returns:

the root node for the resulting tree.

buildEncapsulationTree

public static ITreeNode<org.openjdk.jmc.common.item.IItem> buildEncapsulationTree(org.openjdk.jmc.common.item.IItemCollection items,
                                                                                  boolean allowInstants,
                                                                                  boolean ignoreThread,
                                                                                  ItemTreeBuilder.IItemTreeBuilderCallback callback)

Builds a tree where events that wrap other events, time wise, are higher up in the hierarchy.

Parameters:

items - the items to build a tree from

allowInstants - true to allow instant events in the resulting tree

ignoreThread - true to make the algorithm not care about event thread, can be used for VM level events. It's up to the caller to make sure this is safe to do.

callback - callback used to determine whether or not to continue building the encapsulation tree

Returns:

the root node for the resulting tree.
