SizeF

• java.lang.Object

Fields Summary
private final float	mWidth
private final float	mHeight

Constructors Summary

public SizeF(float width, float height) Create a new immutable SizeF instance. Both the {@code width} and the {@code height} must be a finite number. In particular, {@code NaN} and positive/negative infinity are illegal values. param width The width of the size param height The height of the size throws IllegalArgumentException if either {@code width} or {@code height} was not finite. mWidth = checkArgumentFinite(width, "width"); mHeight = checkArgumentFinite(height, "height");

Methods Summary
public boolean	equals(java.lang.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 {@link Float#floatToIntBits(float)} returns the identical {@code int} value when applied to each. return {@code true} if the objects were equal, {@code false} otherwise if (obj == null) { return false; } if (this == obj) { return true; } if (obj instanceof SizeF) { final SizeF other = (SizeF) obj; return mWidth == other.mWidth && mHeight == other.mHeight; } return false;
public float	getHeight() Get the height of the size (as an arbitrary unit). return height return mHeight;
public float	getWidth() Get the width of the size (as an arbitrary unit). return width return mWidth;
public int	hashCode() {@inheritDoc} return Float.floatToIntBits(mWidth) ^ Float.floatToIntBits(mHeight);
private static java.lang.NumberFormatException	invalidSizeF(java.lang.String s) throw new NumberFormatException("Invalid SizeF: \"" + s + "\"");
public static android.util.SizeF	parseSizeF(java.lang.String string) Parses the specified string as a size value. The ASCII characters {@code \}{@code u002a} ('*') and {@code \}{@code u0078} ('x') are recognized as separators between the width and height. For any {@code SizeF s}: {@code SizeF.parseSizeF(s.toString()).equals(s)}. However, the method also handles sizes expressed in the following forms: "width{@code x}height" or "width{@code *}height" {@code => 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 {@code 'x'} (such as a float in hexadecimal string format). {@code 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 } param string the string representation of a size value. return the size value represented by {@code string}. throws NumberFormatException if {@code string} cannot be parsed as a size value. throws NullPointerException if {@code string} was {@code null} checkNotNull(string, "string must not be null"); int sep_ix = string.indexOf('*"); if (sep_ix < 0) { sep_ix = string.indexOf('x"); } if (sep_ix < 0) { throw invalidSizeF(string); } try { return new SizeF(Float.parseFloat(string.substring(0, sep_ix)), Float.parseFloat(string.substring(sep_ix + 1))); } catch (NumberFormatException e) { throw invalidSizeF(string); } catch (IllegalArgumentException e) { throw invalidSizeF(string); }
public java.lang.String	toString() Return the size represented as a string with the format {@code "WxH"} return string representation of the size return mWidth + "x" + mHeight;
