computeType

public Class computeType(IEnv env)
                  throws VerifyingException

Description copied from class: ExpressionNode

Compute the static type of the expression (nodes should not call this method directly). Called by getType.

Overrides:

computeType in class ExpressionNode

Tags copied from class: ExpressionNode

Parameters:

env - environment of name bindings, etc.

Throws:

VerifyingException - if expression is illegal
