@Deprecated public abstract class AbstractArrayConverter extends Object implements Converter
????
Replaced by the new ArrayConverter implementation

Convenience base class for converters that translate the String representation of an array into a corresponding array of primitives object. This class encapsulates the functionality required to parse the String into a list of String elements that can later be individually converted to the appropriate primitive type.

The input syntax accepted by the parseElements() method is designed to be compatible with the syntax used to initialize arrays in a Java source program, except that only String literal values are supported. For maximum flexibility, the surrounding '{' and '}' characters are optional, and individual elements may be separated by any combination of whitespace and comma characters.

    • NO_DEFAULT

      public static final Object NO_DEFAULT
      ????
      This is a special reference that can be passed as the "default object" to the constructor to indicate that no default is desired. Note that the value 'null' cannot be used for this purpose, as the caller may want a null to be returned as the default.

    • parseElements

      protected List parseElements(String svalue)
      ????

      Parse an incoming String of the form similar to an array initializer in the Java language into a List individual Strings for each element, according to the following rules.

      • The string is expected to be a comma-separated list of values.
      • The string may optionally have matching '{' and '}' delimiters around the list.
      • Whitespace before and after each element is stripped.
      • Elements in the list may be delimited by single or double quotes. Within a quoted elements, the normal Java escape sequences are valid.
