INVALID_STATE_ERR: Raised if detach() has already been invoked on this object.

cloneRange

public Range cloneRange()

Compare the boundary-points of two Ranges in a document.

Parameters: how A code representing the type of comparison, as defined above. sourceRange The Range on which this current Range is compared to.
