public class ListAttribute extends ArrayList<String> implements com.esotericsoftware.kryo.KryoSerializable
This class implements an utility object typically used for setting attributes.
It is possible to pass to the constructor a string containing values, separated by a customizable delimiter character (the default one is the character |), in order to automatically obtain a list containing the values.
The class exposes the getter methods to find the values in a smart way; it is possible to query the list even on positions greater than the size of the list itself; in that case a default value will be returned, that can be global or local, both customizable.

    • getString

      public String getString(int i, String def)
      Extracts a String from the list.
      Parameters:
      i - The position of the String to extract
      def - The default value returned if the String in the desired position is null, or when the position is greater than the size of the list and the global default value is null
      Returns:
      The String in the desired position. If the String is null it returns the default value passed as parameter. If the position is greater than the size of the list and the global default value (the one set with the method setDefault(java.lang.String)) is null, it returns the default value passed as parameter; if the position is greater than the size of the list and the global default value is not null, it returns the global default value

    • getDouble

      public Double getDouble(int i, Double def)
      Extracts a Double value from the list.
      Parameters:
      i - The position of the Double to extract
      def - The default value returned if the Double in the desired position is null, or when the position is greater than the size of the list and the global default value is null
      Returns:
      The Double in the desired position. If the Double is null it returns the default value passed as parameter. If the position is greater than the size of the list and the global default value (the one set with the method setDefault(java.lang.String)) is null, it returns the default value passed as parameter; if the position is greater than the size of the list and the global default value is not null, it returns the global default value

    • getdouble

      Returns:
      The double in the desired position. If the double is null it returns the default value passed as parameter. If the position is greater than the size of the list and the global default value (the one set with the method setDefault(java.lang.String)) is null, it returns the default value passed as parameter; if the position is greater than the size of the list and the global default value is not null, it returns the global default value
