  • package trees

    A library for easily manipulating trees of operators.

    A library for easily manipulating trees of operators. Operators that extend TreeNode are granted the following interface:

    • Scala collection like methods (foreach, map, flatMap, collect, etc)

    - transform - accepts a partial function that is used to generate a new tree. When the partial function can be applied to a given tree segment, that segment is replaced with the result. After attempting to apply the partial function to a given node, the transform function recursively attempts to apply the function to that node's children.

    • debugging support - pretty printing, easy splicing of trees, etc.

Contexts of TreeNodes, including location, SQL text, object type and object name. The only supported object type is "VIEW" now. In the future, we may support SQL UDF or other objects which contain SQL text.
