## Interface Functions Detail

### `bool canParseString(a[, v], str);`

Test whether an WordGraph can parse a string completely.

#### Parameters

`a` | The WordGraph to use for parsing.
`v` | Optionally, the descriptor of the vertex to start at. Defaults to the root.
`str` | The string to parse.

#### Returns

`bool` | `true` if the WordGraph parses `str` , starting at `v`, completely and `false` otherwise.

#### Remarks

This has not implemented yet.

#### Data Races

Thread safety unknown!

### `TVertexDescriptor getSuccessor(a, v, str);`

Gets the successor for a given vertex and an edge label.

#### Parameters

`a` | The WordGraph to query for its successor.
`v` | The descriptor fo the vertex to get the successor for.
`str` | The label.

#### Returns

`TVertexDescriptor` | A vertex descriptor or nil if successor is not defined.

#### Data Races

Thread safety unknown!

#### See Also

- getNil
- parseString

### `TVertexDescriptor parseString(a, v, beginIt, endIt); TVertexDescriptor parseString(a, v, str);`

Parses a string one character at a time and moves accordingly in the WordGraph.

#### Parameters

`a` | An WordGraph.
`v` | The descriptor of the vertex to start at.
`str` | The ContainerConcept to parse.
`beginIt` | Begin iterator to sequence to parse. Set to the first character that could not be parsed or to the value of endIt if all of the string was parsed.
`endIt` | End iterator to sequence to parse.

#### Returns

`TVertexDescriptor` | The vertex descriptor of the state that was reached after parsing.

The parsing stops before getSuccessor reaches the nil state or if the complete sequence is read.

#### Data Races

Thread safety unknown!
