public final class DiskTreebank
A DiskTreebank
is a Collection
of
Tree
s.
A DiskTreebank
object stores merely the information to
get at a corpus of trees that is stored on disk. Access is usually
via apply()'ing a TreeVisitor to each Tree in the Treebank or by using
an iterator() to get an iteration over the Trees.

File

TreePprocessor
.
This is useful if one wants to map the original file and
directory structure over to a set of modified trees. New code
might prefer to build trees with labels that implement
HasIndex.
