Method Detail

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Implementation as proposed by Joshua Block in Effective Java (Addison-Wesley 2001), which supplies an even distribution and is relatively fast. It is created from field f as follows:

• boolean -- code = (f ? 0 : 1)
• byte, char, short, int -- code = (int)f
• long -- code = (int)(f ^ (f >>>32))
• float -- code = Float.floatToIntBits(f);
• double -- long l = Double.doubleToLongBits(f); code = (int)(l ^ (l >>> 32))
• all Objects, (where equals( ) calls equals( ) for this field) -- code = f.hashCode( )
• Array -- Apply above rules to each element

Combining the hash code(s) computed above: result = 37 * result + code;

Overrides:

hashCode in class Object

Returns:

(int) ( result >>> 32 ) ^ (int) result;
