Method Detail

containsValue

public boolean containsValue(float v)

Description copied from interface: Long2FloatMap

Returns true if this map maps one or more keys to the specified value.

Specified by:

containsValue in interface Long2FloatMap

See Also:

Map.containsValue(Object)

containsValue

@Deprecated
public boolean containsValue(java.lang.Object ov)

Deprecated. Please use the corresponding type-specific method instead.

Specified by:

containsValue in interface Long2FloatMap

Specified by:

containsValue in interface java.util.Map<java.lang.Long,java.lang.Float>

putAll

public void putAll(java.util.Map<? extends java.lang.Long,? extends java.lang.Float> m)

Specified by:

putAll in interface java.util.Map<java.lang.Long,java.lang.Float>

long2FloatEntrySet

public it.unimi.dsi.fastutil.objects.ObjectSet<Long2FloatMap.Entry> long2FloatEntrySet()

Description copied from interface: Long2FloatMap

Returns a type-specific set view of the mappings contained in this map.

This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Map.entrySet() so that it returns an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

long2FloatEntrySet in interface Long2FloatMap

Returns:

a type-specific set view of the mappings contained in this map.

See Also:

Map.entrySet()

entrySet

@Deprecated
public it.unimi.dsi.fastutil.objects.ObjectSet<java.util.Map.Entry<java.lang.Long,java.lang.Float>> entrySet()

Deprecated. Please use the corresponding type-specific method instead.

Returns a set view of the mappings contained in this map.

Specified by:

entrySet in interface Long2FloatMap

Specified by:

entrySet in interface java.util.Map<java.lang.Long,java.lang.Float>

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public it.unimi.dsi.fastutil.longs.LongSet keySet()

Description copied from interface: Long2FloatMap

Specified by:

keySet in interface Long2FloatMap

Specified by:

keySet in interface java.util.Map<java.lang.Long,java.lang.Float>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public it.unimi.dsi.fastutil.floats.FloatCollection values()

Description copied from interface: Long2FloatMap

Specified by:

values in interface Long2FloatMap

Specified by:

values in interface java.util.Map<java.lang.Long,java.lang.Float>

Returns:

a set view of the values contained in this map.

isEmpty

public boolean isEmpty()

Specified by:

Overrides:
