Method Detail

### readTree

    public Tree readTree()
                  throws IOException

  Description copied from class: `PennTreeReader`
  Reads a single tree in standard Penn Treebank format from the input stream. The method supports additional parentheses around the tree (an unnamed ROOT node) so long as they are balanced. If the token stream ends before the current tree is complete, then the method will throw an `IOException`.

  Note that the method will skip malformed trees and attempt to read additional trees from the input stream. It is possible, however, that a malformed tree will corrupt the token stream. In this case, an `IOException` will eventually be thrown.

  Specified by:
    `readTree` in interface `TreeReader`
  Overrides:
    `readTree` in class `PennTreeReader`
  Returns:
    A single tree, or `null` at end of token stream.
  Throws:
    `IOException`
