Class AbstractArrayConverter

  • All Implemented Interfaces:
    Converter
    Direct Known Subclasses:
    BooleanArrayConverter, ByteArrayConverter, CharacterArrayConverter, DoubleArrayConverter, FloatArrayConverter, IntegerArrayConverter, LongArrayConverter, ShortArrayConverter, StringArrayConverter
    @Deprecated
public abstract class AbstractArrayConverter
extends java.lang.Object
implements Converter
    Deprecated.
    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.

      Fields 
      Modifier and Type Field Description
      protected java.lang.Object defaultValue
      Deprecated.
      The default value specified to our Constructor, if any.
      static java.lang.Object NO_DEFAULT
      Deprecated.
      This is a special reference that can be passed as the "default object" to the constructor to indicate that no default is desired.
      protected static java.lang.String[] strings
      Deprecated.
      Model object for string arrays.
      protected boolean useDefault
      Deprecated.
      Should we return the default value on conversion errors?

      • NO_DEFAULT

        public static final java.lang.Object NO_DEFAULT
        Deprecated.
        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.

      • convert

        public abstract java.lang.Object convert​(java.lang.Class type,
                                         java.lang.Object value)
        Deprecated.
        Convert the specified input object into an output object of the specified type. This method must be implemented by a concrete subclass.
        Specified by:
        convert in interface Converter
        Parameters:
        type - Data type to which this value should be converted
        value - The input value to be converted
        Returns:
        The converted value
        Throws:
        ConversionException - if conversion cannot be performed successfully

      • parseElements

        protected java.util.List<java.lang.String> parseElements​(java.lang.String svalue)
        Deprecated.

        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.
        Parameters:
        svalue - String value to be parsed
        Returns:
        The parsed list of String values
        Throws:
        ConversionException - if the syntax of svalue is not syntactically valid
        java.lang.NullPointerException - if svalue is null
