Detailed Description

Two or more transducers do not have the same type.

This can happen if (1) the calling and called transducer in a binary operation, (2) two transducers in a pair of transducers, (3) two consecutive transducers coming from an HfstInputStream or (4) two transducers in a function taking two or more transducers as arguments do not have the same type.

An example:

 hfst.set_default_fst_type(hfst.types.TROPICAL_OPENFST_TYPE)
 tr1 = hfst.regex('foo')
 tr2 = hfst.regex('bar')
 tr2.convert(hfst.types.FOMA_TYPE)
 try:
     tr1.disjunct(tr2)
 except hfst.exceptions.TransducerTypeMismatchException:
     print('The implementation types of transducers must be the same.')
