From class
java.lang.Object
|
Create a new immutable SizeF instance.
Both the width
and the height
must be a finite number.
In particular, NaN
and positive/negative infinity are illegal values.
width | The width of the size |
---|---|
height | The height of the size |
IllegalArgumentException | if either width or height was not finite.

Check if this size is equal to another size.
Two sizes are equal if and only if both their widths and heights are the same.
For this purpose, the width/height float values are considered to be the same if and only
if the method floatToIntBits(float)
returns the identical int
value
when applied to each.
obj | the object to compare this instance with. |
---|
true
if the objects were equal, false
otherwise
Get the height of the size (as an arbitrary unit).
Get the width of the size (as an arbitrary unit).
Returns an integer hash code for this object. By contract, any two
objects for which equals(Object)
returns true
must return
the same hash code value. This means that subclasses of Object
usually override both methods or neither method.
Note that hash values must not change over time unless information used in equals comparisons also changes.
See Writing a correct
hashCode
method
if you intend implementing your own hashCode
method.
Parses the specified string as a size value.
The ASCII characters \
u002a
('*') and
\
u0078
('x') are recognized as separators between
the width and height.
For any SizeF s
: SizeF.parseSizeF(s.toString()).equals(s)
.
However, the method also handles sizes expressed in the
following forms:
"widthx
height" or
"width*
height" => new SizeF(width, height)
,
where width and height are string floats potentially
containing a sign, such as "-10.3", "+7" or "5.2", but not containing
an 'x'
(such as a float in hexadecimal string format).
SizeF.parseSizeF("3.2*+6").equals(new SizeF(3.2f, 6.0f)) == true
SizeF.parseSizeF("-3x-6").equals(new SizeF(-3.0f, -6.0f)) == true
SizeF.parseSizeF("4 by 3") => throws NumberFormatException
