Method Detail

containsValue

public boolean containsValue(long v)

Description copied from interface: Float2LongMap

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

Specified by:

containsValue in interface Float2LongMap

See Also:

Map.containsValue(Object)

containsValue

@Deprecated
public boolean containsValue(Object ov)

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

Specified by:

Specified by:

containsValue in interface Map<Float,Long>

putAll

public void putAll(Map<? extends Float,? extends Long> m)

float2LongEntrySet

public ObjectSet<Float2LongMap.Entry> float2LongEntrySet()

Description copied from interface: Float2LongMap

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:

float2LongEntrySet in interface Float2LongMap

Returns:

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

See Also:

Map.entrySet()

entrySet

@Deprecated
public ObjectSet<Map.Entry<Float,Long>> entrySet()

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

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

Note that this specification strengthens the one given in Map.entrySet().

Specified by:

entrySet in interface Float2LongMap

Specified by:

entrySet in interface Map<Float,Long>

Returns:

a set view of the mappings contained in this map.

See Also:

keySet

public FloatSet keySet()

Description copied from interface: Float2LongMap

Note that this specification strengthens the one given in Map.keySet().

Specified by:

keySet in interface Float2LongMap

Specified by:

keySet in interface Map<Float,Long>

Returns:

a set view of the keys contained in this map.

a set view of the values contained in this map.

Map.values()

Returns the value to which the specified key is mapped, or the defaultValue if this map contains no mapping for the key.

Specified by:

Map.replace(Object, Object, Object)

computeIfAbsent

public long computeIfAbsent(float key,
                            DoubleToLongFunction mappingFunction)

Description copied from interface: Float2LongMap

If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map.

Note that contrarily to the default computeIfAbsent(), it is not possible to not add a value for a given key, since the mappingFunction cannot return null. If such a behavior is needed, please use the corresponding nullable version.

Specified by:

computeIfAbsent in interface Float2LongMap

Parameters:

key - key with which the specified value is to be associated.

mappingFunction - the function to compute a value.

Returns:

the current (existing or computed) value associated with the specified key.

See Also:

Map.computeIfAbsent(Object, java.util.function.Function)

computeIfAbsentNullable

public long computeIfAbsentNullable(float key,
                                    DoubleFunction<? extends Long> mappingFunction)

Description copied from interface: Float2LongMap

If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map unless it is null.

Note that this version of computeIfAbsent() should be used only if you plan to return null in the mapping function.

Specified by:

computeIfAbsentNullable in interface Float2LongMap

Parameters:

key - key with which the specified value is to be associated.

mappingFunction - the function to compute a value.

Returns:

the current (existing or computed) value associated with the specified key, or the default return value if the computed value is null.

See Also:

Map.computeIfAbsent(Object, java.util.function.Function)

computeIfAbsentPartial

public long computeIfAbsentPartial(float key,
                                   Float2LongFunction mappingFunction)

Description copied from interface: Float2LongMap

If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map, unless the key is not present in the given mapping function.

This version of computeIfAbsent() uses a type-specific version of fastutil's Function. Since Function has a containsKey() method, it is possible to avoid adding a key by having containsKey() return false for that key.

Specified by:

computeIfAbsentPartial in interface Float2LongMap

Parameters:

key - key with which the specified value is to be associated.

mappingFunction - the function to compute a value.

Returns:

the current (existing or computed) value associated with the specified key.

See Also:

Map.computeIfAbsent(Object, java.util.function.Function)

computeIfPresent

public long computeIfPresent(float key,
                             BiFunction<? super Float,? super Long,? extends Long> remappingFunction)

Description copied from interface: Float2LongMap

If the value for the specified key is present, attempts to compute a new mapping given the key and its current mapped value.

Specified by:

computeIfPresent in interface Float2LongMap

Parameters:

key - key with which the specified value is to be associated.

remappingFunction - the function to compute a value.

Returns:

the new value associated with the specified key, or the default return value if none.

See Also:

Map.computeIfPresent(Object, java.util.function.BiFunction)

compute

public long compute(float key,
                    BiFunction<? super Float,? super Long,? extends Long> remappingFunction)

Description copied from interface: Float2LongMap

Attempts to compute a mapping for the specified key and its current mapped value (or null if there is no current mapping).

If the function returns null, the mapping is removed (or remains absent if initially absent). If the function itself throws an (unchecked) exception, the exception is rethrown, and the current mapping is left unchanged.

Specified by:

compute in interface Float2LongMap

Parameters:

key - key with which the specified value is to be associated.

remappingFunction - the function to compute a value.

Returns:

the new value associated with the specified key, or the default return value if none.

See Also:

Map.compute(Object, java.util.function.BiFunction)

merge

public long merge(float key,
                  long value,
                  BiFunction<? super Long,? super Long,? extends Long> remappingFunction)

Description copied from interface: Float2LongMap

If the specified key is not already associated with a value, associates it with the given value. Otherwise, replaces the associated value with the results of the given remapping function, or removes if the result is null.

Specified by:

merge in interface Float2LongMap

Parameters:

key - key with which the resulting value is to be associated.

value - the value to be merged with the existing value associated with the key or, if no existing value is associated with the key, to be associated with the key.

remappingFunction - the function to recompute a value if present.

Returns:

the new value associated with the specified key, or the default return value if no value is associated with the key.
