computeIsConstant

public boolean computeIsConstant(IEnv env)
Description copied from class: ExpressionNode
Compute whether this expression is a constant (nodes should not call this method directly). Called by the isConstant method.
Overrides:
computeIsConstant in class ExpressionNode
Tags copied from class: ExpressionNode
Parameters:
env - environment of name bindings, etc.
Throws:
VerifyingException - if expression is illegal.
