All Implemented Interfaces:

Converter

Direct Known Subclasses:

BooleanArrayConverter, ByteArrayConverter, CharacterArrayConverter, DoubleArrayConverter, FloatArrayConverter, IntegerArrayConverter, LongArrayConverter, ShortArrayConverter, StringArrayConverter

Deprecated.
Replaced by the new ArrayConverter implementation
```
@Deprecated
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.

Field Summary

Fields
Modifier and Type	Field and Description
`protected Object`	`defaultValue` Deprecated. The default value specified to our Constructor, if any.
`static 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 String[]`	`strings` Deprecated. Model object for string arrays.
`protected boolean`	`useDefault` Deprecated. Should we return the default value on conversion errors?

Constructor Summary

Constructors
Constructor and Description
`AbstractArrayConverter()` Deprecated. Create a `Converter` that will throw a `ConversionException` if a conversion error occurs.
`AbstractArrayConverter(Object defaultValue)` Deprecated. Create a `Converter` that will return the specified default value if a conversion error occurs.

Method Summary

Methods
Modifier and Type	Method and Description
`abstract Object`	`convert(Class type, Object value)` Deprecated. Convert the specified input object into an output object of the specified type.
`protected List`	`parseElements(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.

    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.

```
public abstract Object convert(Class type,
             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 List parseElements(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
    
    NullPointerException - if svalue is null
