Stores this object back into Perforce, creating it if it didn't already exist.

Overrides:

commit in class Mapping

getCache

public HashDecay getCache()

Description copied from class: SourceControlObject

Returns the HashDecay instance for this class

Overrides:

getCache in class SourceControlObject

getLabel

public static Label getLabel(Env env,
                             String name,
                             boolean force)

Returns a Label with the specified name, or null if not found.

Parameters:

env - Environment to use when working with P4.

name - Name of the label to find.

force - Indicates that the Label should be sync'd.

getLabel

public static Label getLabel(String name)

Returns a Label with the specified name, or null if not found.

Parameters:

name - Name of the label to find.

getLabelIterator

public static Iterator getLabelIterator(Env env)

Parameters:

env - Environment to use when working with P4

Returns:

Iterator for all labels (set of Label instances).

getLabelNames

public static Enumeration getLabelNames(Env env)

Parameters:

env - Environment to use when working with P4

Returns:

List of all label names (Enumeration of String instances).

getLabels

public static Enumeration getLabels(Env env)

Parameters:

env - Environment to use when working with P4

Returns:

Enumeration of all labels (set of Label instances).

loadLabels

public static void loadLabels(Env env)

Loads a list of all the labels into an internal class HashDecay. This method will only be called by the class itself if the HashDecay is empty. Users should call this method if they believe the p4 label information needs to be brought up to date.

Parameters:

env - Environment to use when working with P4
