Method Detail

getKey

public K getKey()

Specified by:

getKey in interface Map.Entry<K,V>

getValue

public V getValue()

Specified by:

getValue in interface Map.Entry<K,V>

setValue

public V setValue(V o)

Specified by:

setValue in interface Map.Entry<K,V>

getByteSize

public int getByteSize()

Description copied from interface: SizeMeasurable

Determines the byte-size of this object

Specified by:

getByteSize in interface SizeMeasurable

getByteSize

public int getByteSize(SizeOf sizeof)

Description copied from interface: SizeMeasurable

Determines the byte-size of this object using the given SizeOf instance. A SizeOf instance stores a Set already counted objects. So this method is typically called by SizeOf itself (recursion).

Specified by:

getByteSize in interface SizeMeasurable

toString

public String toString()

Overrides:

toString in class Object
