Public Methods

public boolean canConvert (TypeDescriptor sourceType, TypeDescriptor targetType)

Return true if the type converter can convert the specified type to the desired target type.

Parameters

public Object convertValue (Object value, TypeDescriptor sourceType, TypeDescriptor targetType)

Convert (may coerce) a value from one type to another, for example from a boolean to a string. The typeDescriptor parameter enables support for typed collections - if the caller really wishes they can have a List<Integer> for example, rather than simply a List.

Parameters
value the value to be converted
sourceType a type descriptor that supplies extra information about the source object
targetType a type descriptor that supplies extra information about the requested result type
Returns
  • the converted value
