Constructor Detail

TreeMap.Entry

TreeMap.Entry(java.lang.Object key,
              java.lang.Object value,
              TreeMap.Entry parent)

Make a new cell with given key, value, and parent, and with null child links, and BLACK color.

Method Detail

getKey

public java.lang.Object getKey()

Returns the key.

Specified by:

getKey in interface Map.Entry

getValue

public java.lang.Object getValue()

Returns the value associated with the key.

Specified by:

getValue in interface Map.Entry

setValue

public java.lang.Object setValue(java.lang.Object value)

Replaces the value currently associated with the key with the given value, and returns the old value.

Specified by:

setValue in interface Map.Entry

equals

public boolean equals(java.lang.Object o)

Description copied from interface:
Compares the specified Object with this Entry for equality. Returns true if the given object is also a Map.Entry and the two Entries represent the same mapping. More formally, two Entries e1 and e2 represent the same mapping if (e1.getKey()==null ? e2.getKey()==null : e1.getKey().equals(e2.getKey())) (e1.getValue()==null ? e2.getValue()==null : e1.getValue().equals(e2.getValue())) . This ensures that the equals method works properly across different implementations of the Map.Entry interface.

Specified by:

equals in interface Map.Entry

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Description copied from interface:
Returns the hash code value for this Map.Entry. The hash code of a Map.Entry e is defined to be: (e.getKey()==null ? 0 : e.getKey().hashCode()) ^ (e.getValue()==null ? 0 : e.getValue().hashCode()) This ensures that e1.equals(e2) implies that e1.hashCode()==e2.hashCode() for any two Entries e1 and e2, as required by the general contract of Object.hashCode.

Specified by:

hashCode in interface Map.Entry

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
