Returns:

setTime

public void setTime(java.lang.Long time)

public java.lang.Long getTime()

Description copied from interface: Setting

Get the time for this setting.

Setting.setTime(java.lang.Long)

setNew

public void setNew(boolean isNew)

Description copied from interface: Setting

Mark setting as new. For default preferences. A setting is marked as new, if it has been seen in the current session. Methods like IPreferences.get(java.lang.String, java.lang.String), can be called from different parts of the code with the same key. In this case, the supplied default value must match. However, this is only an error if the mismatching default value has been seen in the same session (and not loaded from cache).

Specified by:

setNew in interface Setting<T>

Parameters:

isNew - true, if it is new

isNew

public boolean isNew()

Description copied from interface: Setting

Return if the setting has been marked as new.

Specified by:

Returns:

true, if the setting has been marked as new
