Method Details

setExpectInteger

void setExpectInteger()
               throws DOMException

If the value is a proxy that ever produces other than an integer number (without calc() involvement), an exception should be thrown later.

Throws:

DOMException - TYPE_MISMATCH_ERR if the value is a constant number and not an integer.

Test whether this is a numeric value that is less than zero.

Returns:

true if this is a numeric value and its value is negative.

the unit type, CSS_INVALID if the unit or type are not valid.
