public class BooleanSyntaxException

extends FidoException

Thrown when an error occurs while constructing or using a BooleanTree. If that was too vague :), it can happen when

1. When adding a leaf node to the tree, if the tree is not empty and the last node added was not a subclass of BooleanNode.
2. When adding a subclass of BooleanNode as the first node of a tree. The first node must be a leaf node, then add a subclass of BooleanNode, and the leaf node will become its Left branch.
3. An attempt to close a group (end a parenthesis), when none where opened.
4. When the tree is complete, if there was an open parenthesis which was not closed.
5. When the tree is complete, if there was a subclass of BooleanNode ending the tree. This means there is no Right branch on the last BooleanNode.
