Field Detail

STAYS_IN_SUBTREE

static final int STAYS_IN_SUBTREE

If is set, then all nodes in the result of eval(x, c) are guaranteed to be in the subtree rooted at x.

Constant Field Values

SINGLE_LEVEL

static final int SINGLE_LEVEL

If this is set, then all nodes in the result of eval(x, c) are guaranteed to be at the same level of the tree. More precisely, define the level of a node to be the number of ancestors it has, and then define an expression to be single-level if and only if there exists an integer n such that for any node x, for any node y in the result of evaluating the expression with respect to x, the difference between the level of x and the level of y is equal to n. For example, the children axis is single-level but the descendants axis is not.
