Method Detail

addEdge

public void addEdge(java.lang.String chars,
                    int target)

addEdge This method will add an edge to the FAState. It will create a new edge if there are no chars (the lambda edge), otherwise it will find the index from the target passed in, and create a new edge with the target index of the target passed in, and the characters passed in.
If the target is not found, it will produce an error.

Parameters:

chars - The set of characters associated with the edge to be created.

target - The target index in this state.

edge

public FAEdge edge(int index)

edge This method will return the edge at the specified index for this state.

Parameters:

index - The index of the edge that will be returned.

Returns:

The FAEdge at the specified index.

edgeCount

public int edgeCount()

edgeCount The number of edges in this FAState.

Returns:

The number of edges in this FAState.
