From source file:org.ejbca.ui.cli.FieldEditor.java

/** Lists, Gets or sets fields in a Bean.
 * /*  ww w . j  av  a2  s .  c om*/
 * @param listOnly if true, fields will be listed, and nothing more will happen.
 * @param getOnly if true (and listOnly is false), will get the value of a field and nothing else will happen
 * @param name the name of the Bean to be modified
 * @param field the field name to get or set
 * @param value the value to set, of we should set a new value
 * @param obj the Bean to list, get or set fields
 * @return true if we only listed or got a value, i.e. if nothing was modified, false is we set a value.
 * @throws FieldNotFoundException if field was not found.
