Class Overview

Immutable class for describing width and height dimensions in some arbitrary unit.

Width and height are finite values stored as a floating point representation.

Summary

Public Constructors
SizeF(float width, float height)
Create a new immutable SizeF instance.
Public Methods
boolean equals(Object obj)
Check if this size is equal to another size.
float getHeight()
Get the height of the size (as an arbitrary unit).
float getWidth()
Get the width of the size (as an arbitrary unit).
int hashCode()
Returns an integer hash code for this object.
String toString()
Return the size represented as a string with the format "WxH"

Inherited Methods
From class java.lang.Object

Public Constructors

public SizeF (float width, float height)

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.

Parameters
width The width of the size
height The height of the size
Throws
IllegalArgumentException if either width or height was not finite.

Public Methods

public boolean equals (Object obj)

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.

Parameters
obj the object to compare this instance with.
Returns
  • true if the objects were equal, false otherwise

public float getHeight ()

Get the height of the size (as an arbitrary unit).

Returns
  • height

public float getWidth ()

Get the width of the size (as an arbitrary unit).

Returns
  • width

public int hashCode ()

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.

Returns
  • this object's hash code.

public String toString ()

Return the size represented as a string with the format "WxH"

Returns
  • string representation of the size
