getIndex

public abstract int getIndex()

An implementation-specific index for this transition object, can be used to index into arrays of per-transition parameters.

getInput

public abstract java.lang.Object getInput()

The input symbol or object appearing on this transition.

getOutput

public abstract java.lang.Object getOutput()

The output symbol or object appearing on this transition.

getWeight

public abstract double getWeight()

The weight (between infinity and -infinity) associated with taking this transition with this input/output.

getSourceState

public abstract Transducer.State getSourceState()

The state we were in before taking this transition.

getDestinationState

public abstract Transducer.State getDestinationState()

The state we are in after taking this transition.

getInputPositionIncrement

public int getInputPositionIncrement()

The number of input positions that this transition consumes. This allows for transition that consume variable amounts of the sequences.
