Class Outputs<T>

Represents the outputs for an FST, providing the basic algebra required for building and traversing the FST.

Note that any operation that returns NO_OUTPUT must return the same singleton object from NoOutput.

LUCENENET IMPORTANT: If T is a collection type, it must implement System.Collections.IStructuralEquatable in order to properly compare its nested values.

Note

This API is experimental and might change in incompatible ways in the next release.
