public class Progress
extends Object

Utility to assist with generation of progress reports. Applications build a hierarchy of Progress instances, each modelling a phase of execution. The root is constructed with Progress(). Nodes for sub-phases are created by calling addPhase().

方法详细资料

addPhase

public Progress addPhase(String status)

Adds a named node to the tree.

addPhase

public Progress addPhase()

Adds a node to the tree.

startNextPhase

public void startNextPhase()

Called during execution to move to the next phase at this level in the tree.

phase

public Progress phase()

Returns the current sub-node executing.

complete

public void complete()

Completes this node, moving the parent node to its next child.

set

public void set(float progress)

Called during execution on a leaf node to set its progress.

get

public float get()

Returns the overall progress of the root.

getProgress

public float getProgress()
