Class XWorkBasicConverter

java.lang.Object
  com.opensymphony.xwork2.conversion.impl.DefaultTypeConverter
      com.opensymphony.xwork2.conversion.impl.XWorkBasicConverter

All Implemented Interfaces:

TypeConverter

public class XWorkBasicConverter
extends DefaultTypeConverter

XWork will automatically handle the most common type conversion for you. This includes support for converting to and from Strings for each of the following:

• String
• boolean / Boolean
• char / Character
• int / Integer, float / Float, long / Long, double / Double
• dates - uses the SHORT format for the Locale associated with the current request
• arrays - assuming the individual strings can be coverted to the individual items
• collections - if not object type can be determined, it is assumed to be a String and a new ArrayList is created

Note that with arrays the type conversion will defer to the type of the array elements and try to convert each item individually. As with any other type conversion, if the conversion can't be performed the standard type conversion error reporting is used to indicate a problem occured while processing the type conversion.

Description copied from interface: TypeConverter

Converts the given value to a given type. The OGNL context, target, member and name of property being set are given. This method should be able to handle conversion in general without any context, target, member or property name specified.

Specified by:

convertValue in interface TypeConverter

Overrides:

convertValue in class DefaultTypeConverter

Parameters:

context - context under which the conversion is being done

o - target object in which the property is being set

member - member (Constructor, Method or Field) being set

s - property name being set

value - value to be converted

toType - type to which value is converted

Returns:

Converted value of type toType or TypeConverter.NoConversionPossible to indicate that the conversion was not possible.

isInRange

protected boolean isInRange(Number value,
                            String stringValue,
                            Class toType)

isIntegerType

protected boolean isIntegerType(Class type)
