### Type Members

1.  type Context = (analyzer)#Context
2.  class ContextTree extends AnyRef

   A context tree contains contexts that are indexed by positions.

   A context tree contains contexts that are indexed by positions. It satisfies the following properties:

   1. All context come from compiling the same unit. 2. Child contexts have parent contexts in their outer chain. 3. The `pos` field of a context is the same as `context.tree.pos`, unless that position is transparent. In that case, `pos` equals the position of one of the solid descendants of `context.tree`. 4. Children of a context have non-overlapping increasing positions. 5. No context in the tree has a transparent position.
3.  type Contexts = ArrayBuffer[Global.ContextTree]

8.  def addContext(contexts: Global.Contexts, context: Global.Context): Unit

   Insert a context at correct position into a buffer of context trees.

   Insert a context at correct position into a buffer of context trees. If the `context` has a transparent position, add it multiple times at the positions of all its solid descendant trees.

    Returns the most precise context possible for the given `pos`.

    Returns the most precise context possible for the given `pos`.

    It looks for the finest ContextTree containing `pos`, and then look inside this ContextTree for a child ContextTree located immediately before `pos`. If such a child exists, returns its context, otherwise returns the context of the parent ContextTree.

    This is required to always return a context which contains the all the imports declared up to `pos` (see scala/bug#7280 for a test case).

    Can return None if `pos` is before any valid Scala code.

23.  def locateContextTree(contexts: Global.Contexts, pos: Global.Position): Option[Global.ContextTree]

    Returns the ContextTree containing `pos`, or the ContextTree positioned just before `pos`, or None if `pos` is located before all ContextTrees.
