◆ compareContents()

virtual int klee::NotOptimizedExpr::compareContents ( const Expr b) const
inlineprotectedvirtual

Compares b to this Expr and determines how they are ordered (ignoring their kid expressions - i.e. those returned by getKid()).

Typically this requires comparing internal attributes of the Expr.

Implementations can assume that b and this are of the same kind.

This method effectively defines a partial order over Expr of the same kind (partial because kid Expr are not compared).

This method should not be called directly. Instead compare() should be used.

Parameters
[in]bExpr to compare this to.
Returns
One of the following values:
  • -1 if this is < b ignoring kid expressions.
  • 1 if this is > b ignoring kid expressions.
  • 0 if this and b are not ordered.

< and > are binary relations that express the partial order.
