equals

public boolean equals(java.lang.Object o)

equals

Specified by:

equals in interface java.util.Map

Overrides:

equals in class java.lang.Object

Parameters:

o - Object

Returns:

boolean

hashCode

public int hashCode()

Returns the hash code value for this map. The hash code of a map is defined to be the sum of the hash codes of each entry in the map's entrySet() view. This ensures that t1.equals(t2) implies that t1.hashCode()==t2.hashCode() for any two maps t1 and t2, as required by the general contract of Object.hashCode.

This implementation iterates over entrySet(), calling hashCode on each element (entry) in the Collection, and adding up the results.

Specified by:

hashCode in interface java.util.Map

Overrides:

hashCode in class java.lang.Object

Returns:

the hash code value for this map.

Map.Entry#hashCode(), Object.hashCode(), Object.equals(Object), Set.equals(Object)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
