    public class MultiTrie

extends Trie

The MultiTrie is a Trie of Tries. It stores words and their associated patch commands. The MultiTrie handles patch commands individually (each command by itself).

Constructor Summary
`MultiTrie(boolean forward)` Constructor for the MultiTrie object
`MultiTrie(DataInput is)` Constructor for the MultiTrie object.

Method Summary
`void` `add(CharSequence key, CharSequence cmd)` Add an element to this structure consisting of the given key and patch command.
`CharSequence` `getFully(CharSequence key)` Return the element that is stored in a cell associated with the given key.
`CharSequence` `getLastOnPath(CharSequence key)` Return the element that is stored as last on a path belonging to the given key.
`void` `printInfo(PrintStream out, CharSequence prefix)` Print the given prefix and the position(s) in the Trie where it appears.
`Trie` `reduce(Reduce by)` Remove empty rows from the given Trie and return the newly reduced Trie.
`void` `store(DataOutput os)` Write this data structure to the given output stream.

Constructor Detail

### MultiTrie

    public MultiTrie(DataInput is)
              throws IOException

  Constructor for the MultiTrie object.

  Parameters:
    `is` - the input stream
  Throws:
    `IOException` - if an I/O error occurs

### MultiTrie

    public MultiTrie(boolean forward)

  Constructor for the MultiTrie object

  Parameters:
    `forward` - set to `true` if the elements should be read left to right

Method Detail

### getFully

    public CharSequence getFully(CharSequence key)

  Return the element that is stored in a cell associated with the given key.

  Overrides:
    `getFully` in class `Trie`
  Parameters:
    `key` - the key to the cell holding the desired element
  Returns:
    the element

### getLastOnPath

    public CharSequence getLastOnPath(CharSequence key)

  Return the element that is stored as last on a path belonging to the given key.

  Overrides:
    `getLastOnPath` in class `Trie`
  Parameters:
    `key` - the key associated with the desired element
  Returns:
    the element that is stored as last on a path

### store

    public void store(DataOutput os)
               throws IOException

  Write this data structure to the given output stream.

  Overrides:
    `store` in class `Trie`
  Parameters:
    `os` - the output stream
  Throws:
    `IOException` - if an I/O error occurs

### add

    public void add(CharSequence key,
                    CharSequence cmd)

  Add an element to this structure consisting of the given key and patch command.

  This method will return without executing if the `cmd` parameter's length is 0.

  Parameters:
    `key` - the key
    `cmd` - the patch command

### reduce

    public Trie reduce(Reduce by)

  Remove empty rows from the given Trie and return the newly reduced Trie.

  Overrides:
    `reduce` in class `Trie`
  Parameters:
    `by` - the Trie to reduce
  Returns:
    the newly reduced Trie

### printInfo

    public void printInfo(PrintStream out,
                          CharSequence prefix)

  Print the given prefix and the position(s) in the Trie where it appears.

  Overrides:
    `printInfo` in class `Trie`
  Parameters:
    `prefix` - the desired prefix
