public abstract class AbstractArrayConverter extends 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.

Field Summary | |
---|---|
protected Object | defaultValue
The default value specified to our Constructor, if any. |
static 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. |
protected static String[] | strings Model object for string arrays. |
protected boolean | useDefault
Should we return the default value on conversion errors? |

Model object for string arrays.
Parameters: defaultValue The default value to be returned
Since: 1.8.0
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
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.
Parameters: svalue String value to be parsed
