Class StringArrayConverter
- Converter
public final class StringArrayConverter
Standard
Converter
implementation that converts an incoming
String into an array of String objects. On a conversion failure, returns
a specified default value or throws a
ConversionException
depending
on how this instance is constructed.
There is also some special handling where the input is of type int[].
See method convert for more details.

convert
public Object convert(Class type,
Object value)
Convert the specified input object into an output object of the
specified type.
If the value is already of type String[] then it is simply returned
unaltered.
If the value is of type int[], then a String[] is returned where each
element in the string array is the result of calling Integer.toString
on the corresponding element of the int array. This was added as a
result of bugzilla request #18297 though there is not complete
agreement that this feature should have been added.
In all other cases, this method calls toString on the input object, then
assumes the result is a comma-separated list of values. The values are
split apart into the individual items and returned as the elements of an
array. See class AbstractArrayConverter for the exact input formats
supported.

type
- is the data type to which this value should be converted.
It is expected to be the class for type String[] (though this parameter
is actually ignored by this method).value
- is the input value to be converted. If null then the
default value is returned or an exception thrown if no default value
exists.
