                  throws java.lang.Exception

Description copied from interface: KAREntryHandler

Specified by:

getTypeName in interface KAREntryHandler

handlesType

public boolean handlesType(java.lang.String typeName)

Description copied from interface: KAREntryHandler

This method should return true if this KAREntryHandler can handle the specified type. The type passed in is the binary class name of the file.

Specified by:
