Method Detail

checkTypes

protected final java.lang.Class checkTypes(java.lang.Object obj,
                                           java.lang.Class type)
                                    throws ConversionException

Checks ifobj can converted to type. Subclasses should call this method from the convert method before performing the conversion. It also chooses the appropriate type if type is not contained in the output types but a supertype of it.

---

throwException

protected final void throwException(java.lang.Object o,
                                    java.lang.Class type)
                             throws ConversionException

Throws a generic ConversionException. Subclasses should only use this methods if no other information about the failure of the conversion are available.
Note: The ConversionException is always thrown.

---

getInputTypes

public java.util.Set getInputTypes()

Description copied from interface: Converter

Returns a set containing the classes that are supported as input types. Subtypes of these base classes have to be supported, too.

Example:
If the set contains java.util.List.class, any class that implements java.util.List must be supported.

Note:null is never a valid input type.

Specified by:

getInputTypes in interface Converter

getOutputTypes

public java.util.Set getOutputTypes()

Description copied from interface: Converter

Returns a set containing the classes that are supported as output types. It must be possible to convert each of the input types 55 to each of the output types.

Specified by:
