Functions | |
| HfstTransducer | bracketedReplace (const Rule &rule, bool optional) |
| Unconditional replace, in multiple contexts first: (.* T<a:b>T .*) - [( .* L1 T<a:b>T R1 .*) u (.* L2 T<a:b>T R2 .*)...], where .* = [I:I (+ {tmpMarker (T), <,>} in alphabet) | <a:b>]* then: remove tmpMarker from transducer and alphabet, and do negation: .* - result from upper operations. More... | |
| HfstTransducer | coercion (HfstTransducerPairVector &contexts, HfstTransducer &mapping, StringPairSet &alphabet) |
| A transducer that requires that one of the mappings defined by mapping must occur in each context in contexts. Symbols outside of the matching substrings are mapped to any symbol allowed by alphabet. More... | |
| HfstTransducer | deep_coercion (HfstTransducerPairVector &contexts, HfstTransducer &mapping, StringPairSet &alphabet) |
| A transducer that specifies that a string from the output language of the transducer mapping always has to be mapped to one of its input strings (according to transducer mappings) if it appears in any of the contexts in contexts. Symbols outside of the matching substrings are mapped to any symbol allowed by alphabet. More... | |
| HfstTransducer | deep_restriction (HfstTransducerPairVector &contexts, HfstTransducer &mapping, StringPairSet &alphabet) |
| A transducer that specifies that a string from the output language of the transducer mapping may only be mapped to one of its input strings (according to transducer mappings) if it appears in any of the contexts in contexts. Symbols outside of the matching substrings are mapped to any symbol allowed by alphabet. More... | |
| HfstTransducer | deep_restriction_and_coercion (HfstTransducerPairVector &contexts, HfstTransducer &mapping, StringPairSet &alphabet) |
| A transducer that is equivalent to the intersection of deep_restriction and deep_coercion. More... | |
| HfstTransducer | left_replace_down (HfstTransducerPair &context, HfstTransducer &mapping, bool optional, StringPairSet &alphabet) |
| Inversion of the replace_up and the result needs to be composed on the upper side of the input language. However, matching is done on the output side of mapping. More... | |
| HfstTransducer | left_replace_down_karttunen (HfstTransducerPair &context, HfstTransducer &mapping, bool optional, StringPairSet &alphabet) |
| Inversion of the replace_up and the result needs to be composed on the upper side of the input language. However, matching is done on the output side of mapping. More... | |
| HfstTransducer | left_replace_left (HfstTransducerPair &context, HfstTransducer &mapping, bool optional, StringPairSet &alphabet) |
| Inversion of the replace_up and the result needs to be composed on the upper side of the input language. However, left context matching is done on the input side of mapping and right context on the output side of mapping. More... | |
| HfstTransducer | left_replace_right (HfstTransducerPair &context, HfstTransducer &mapping, bool optional, StringPairSet &alphabet) |
| Inversion of the replace_up and the result needs to be composed on the upper side of the input language. However, left context matching is done on the output side of mapping and right context on the input side of mapping. More... | |
| HfstTransducer | left_replace_up (HfstTransducer &mapping, bool optional, StringPairSet &alphabet) |
| Inversion of the replace_up and the result needs to be composed on the upper side of the input language. More... | |
| HfstTransducer | left_replace_up (HfstTransducerPair &context, HfstTransducer &mapping, bool optional, StringPairSet &alphabet) |
| Inversion of the replace_up and the result needs to be composed on the upper side of the input language. More... | |
| std::ostream & | operator<< (std::ostream &out, const HfstTransducer &t) |
| Write transducer t in AT&T format to ostream out. More... | |
| HfstTransducer | replace_down (HfstTransducerPair &context, HfstTransducer &mapping, bool optional, StringPairSet &alphabet) |
| The same as replace_up, but matching is done on the output side of mapping. More... | |
| HfstTransducer | replace_down (HfstTransducer &mapping, bool optional, StringPairSet &alphabet) |
| The same as replace_down(HfstTransducerPair&, HfstTransducer&, bool, StringPairSet&) but mapping is performed in every context. More... | |
| HfstTransducer | replace_left (HfstTransducerPair &context, HfstTransducer &mapping, bool optional, StringPairSet &alphabet) |
| The same as replace_up, but left context matching is done on the input side of mapping and right context on the output side of mapping. More... | |
| HfstTransducer | replace_right (HfstTransducerPair &context, HfstTransducer &mapping, bool optional, StringPairSet &alphabet) |
| The same as replace_up, but left context matching is done on the output side of mapping and right context on the input side of mapping. More... | |
| HfstTransducer | replace_up (HfstTransducerPair &context, HfstTransducer &mapping, bool optional, StringPairSet &alphabet) |
| A transducer that performs an upward mapping mapping in the context context when the alphabet is alphabet. optional defines whether the mapping is optional. More... | |

| HfstTransducer | restriction (HfstTransducerPairVector &contexts, HfstTransducer &mapping, StringPairSet &alphabet) |

| HfstTransducer | restriction_and_coercion (HfstTransducerPairVector &contexts, HfstTransducer &mapping, StringPairSet &alphabet) |
| A transducer that is equivalent to the intersection of restriction and coercion and requires that the mappings defined by mapping occur always and only in the given contexts in contexts. Symbols outside of the matching substrings are mapped to any symbol allowed by alphabet. More... | |
