Field Detail

PREFIX_SEPARATOR

public static char PREFIX_SEPARATOR

The character used to separate the prefix from the value name when you are using the getObject method with a prefix. You can change the value of this prefix if you want to by changing this static variable. Ex: getObject(User.class, "user") will get all values that begin with "user.".
