addIndices

public void addIndices(java.util.Set<java.lang.Integer> indices,
                       int depth)
Description copied from class: Expr
If this expression has any indices which are >= depth, add (index - depth) to the index set accumulator. The depth increases each time this method recurses through a binder. The default implementation is to assume the expression has no free variables, and thus do nothing. Expressions which contain variables or subexpressions override this behavior.

Specified by:
addIndices in class Expr
Parameters:
indices - The index set accumulator.
depth - The minimum index for a free variable.
