equals

public boolean equals(@Nullable
                      Object object)

calling this method should be avoided at all cost, as the entire object is serialized. This equals can be used to compare map that extends ChronicleMap. So two Chronicle Maps that contain the same data are considered equal, even if the instances of the chronicle maps were of different types

Overrides:

equals in class Object

Parameters:

object - the object that you are comparing against

Returns:

true if the contain the same data

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

@NotNull
public String toString()

Overrides:

toString in class Object

public boolean isEmpty()

containsKey

public boolean containsKey(Object key)

Specified by:

containsKey in interface KeyValueStore<K,V,V>

get
