Interface Wait

java/src/org/openqa/selenium/support/ui/Wait.java:30–46

A generic interface for waiting until a condition is true or not null. The condition may take a single argument of type . @param the argument to pass to any function called

 * @param <F> the argument to pass to any function called

   * Implementations should wait until the condition evaluates to a value that is neither null nor
   * false. Because of this contract, the return type must not be Void.

   * <p>If the condition does not become true within a certain time (as defined by the implementing
   * class), this method will throw a non-specified {@link Throwable}. This is so that an
   * implementor may throw whatever is idiomatic for a given test infrastructure (e.g. JUnit4 would
   * throw {@link AssertionError}).
