Class ImmutableOpenMap<KType,VType>

java.lang.Object

java.util.AbstractMap<KType,VType>

org.elasticsearch.common.collect.ImmutableOpenMap<KType,VType>

All Implemented Interfaces:

Map<KType,VType>

public final class ImmutableOpenMap<KType,VType>
extends AbstractMap<KType,VType>

An immutable map implementation based on open hash map.

Can be constructed using a builder(), or using builder(Map) (which is an optimized option to copy over existing content and modify it).

Method Details

get

public VType get(Object key)

Specified by:

get in interface Map<KType,VType>

Overrides:

get in class AbstractMap<KType,VType>

Returns:

Returns the value associated with the given key or the default value for the key type, if the key is not associated with any value.

Important note: For primitive type values, the value returned for a non-existing key may not be the default value of the primitive type (it may be any value previously assigned to that slot).

getOrDefault

public VType getOrDefault(Object key,
 VType defaultValue)

Returns:

Returns the value associated with the given key or the provided default value if the key is not associated with any value.

containsKey

public boolean containsKey(Object key)

Returns true if this container has an association to a value for the given key.

Specified by:

containsKey in interface Map<KType,VType>

Overrides:

containsKey in class AbstractMap<KType,VType>

containsValue

public boolean containsValue(Object value)

Specified by:

containsValue in interface Map<KType,VType>

Overrides:

containsValue in class AbstractMap<KType,VType>
