Method Detail

getLabel

public java.lang.String getLabel()

Description copied from class: TaskAction

Returns the human-readable name of this action.

getDescription

public java.lang.String getDescription()

Description copied from class: TaskAction

perform

public boolean perform(Project project,
                       Task task,
                       Member member)

Description copied from class: TaskAction

Perform this action on a member of a project, a project or a task. If the project itself is the target, task and member will be null. If a task is the target, then member will be null. If an error occurs while executing the task, then it is the action's responsibility to inform the user. This method can return false to indicate that if the action is being applied to multiple members, it should stop immediately rather than continue to the next member.

Specified by:

perform in class TaskAction

Parameters:

project - the project that is being acted upon

task - the task within the project that is being acted upon; null if acting on a project

member - the specific member within the task to act upon; null if this is a project or task

appliesToSelection

public boolean appliesToSelection(Member[] members)

Description copied from class: TaskAction

Returns true if this action is applicable to any of the specified Members. By overriding this, you can modify whether an action is listed depending on which other members are selected. For example, you could create a command that can only be applied to a singleton selection by checking the length of members and returning false if it is not 1, and otherwise calling the super implementation.

Overrides:

appliesToSelection in class TaskAction

Parameters:

members - a list of zero or more members

Returns:

true is the action can be applied to at least one member

appliesTo

public boolean appliesTo(Project project,
                         Task task,
                         Member member)

Description copied from class: TaskAction

Returns true if this action can be performed on the specified member of a project, project or a task. If the project itself is the target, task and member will be null. If a task is the target, then member will be null. If an error occurs while executing the task, then it is the action's responsibility to inform the user. This method can return false to indicate that if the action is being applied to multiple members, it should stop immediately rather than continue to the next member.

Specified by:

appliesTo in class TaskAction

Parameters:

project - the project that is being acted upon

task - the task within the project that is being acted upon; null if acting on a project

member - the specific member within the task to act upon; null if this is a project or task
