      • getLabel

        public java.lang.String getLabel()
        Description copied from class: TaskAction
        Returns the human-readable name of this action.
        Specified by:
        getLabel in class TaskAction
        Returns:
        the name used to create menu items for this action, localized if possible

      • getDescription

        public java.lang.String getDescription()
        Description copied from class: TaskAction
        Returns a longer description of the action, suitable for use as a tool tip.
        Overrides:
        getDescription in class TaskAction
        Returns:
        a long description of the action, or null

      • performOnSelection

        public boolean performOnSelection​(Member[] members)
        Description copied from class: TaskAction
        Applies this action to all of the specified project members. By overriding this, you can modify what happens when the user tries to initiate this action. For example, you could add a verification dialog and call the super implementation only if the user verifies the action.
        Overrides:
        performOnSelection in class TaskAction
        Returns:
        true if and only if the action is successfully applied to all of the members

      • 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
