public abstract class AbstractArrayConverter extends Object implements Converter
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.

The default value specified to our Constructor, if any. |

Method Summary | |
---|---|
abstract Object | convert(Class type, Object value)
Convert the specified input object into an output object of the
specified type. |
protected List | parseElements(String svalue) Parse an incoming String of the form similar to an array initializer
in the Java language into a
|
Model object for string arrays.
Parameters: type Data type to which this value should be converted value The input value to be converted
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
Throws: ConversionException if the syntax of svalue
is not syntactically valid NullPointerException if svalue
is null
