java.lang.Object org.apache.commons.beanutils.converters.AbstractArrayConverter
ArrayConverter
implementation
public abstract class AbstractArrayConverter
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.
