A stream for reading HFST binary transducers.
An example:
istr = hfst.HfstInputStream('testfile1.hfst')
transducers = []
while not (istr.is_eof()):
transducers.append(istr.read())
istr.close()
print("Read %i transducers in total." % len(transducers))For documentation on the HFST binary transducer format, see here.
| def __init__ | ( | self, | |
filename = None |
|||
| ) |
Create a stream for reading binary transducers.
| filename | The name of the transducer file. If not given, standard input is used. |
| StreamNotReadableException | |
| NotTransducerStreamException | |
| EndOfStreamException | |
| TransducerHeaderException | istr_to_stdin = hfst.HfstInputStream() istr_to_file = hfst.HfstInputStream(filename='transducer.hfst') |
| def close | ( | self | ) |
Close the stream.
If the stream points to standard input, nothing is done.
| def get_type | ( | self | ) |
The type of the first transducer in the stream.
By default, all transducers in a stream have the same type, else a TransducerTypeMismatchException is thrown when reading the first transducer that has a different type than the previous ones.
| def is_bad | ( | self | ) |
Whether badbit is set.
| def is_eof | ( | self | ) |
Whether the stream is at end.
| def is_good | ( | self | ) |
Whether the state of the stream is good for input operations.
| def read | ( | self | ) |
Return next transducer.
| EndOfStreamException |
