Method Details

test

public boolean test(K operand)

Description copied from interface: Reference2BooleanFunction

Specified by:

test in interface java.util.function.Predicate<K>

Specified by:

test in interface Reference2BooleanFunction<K>

apply

@Deprecated
public java.lang.Boolean apply(K key)

Deprecated.

Please use the corresponding type-specific method instead.

Specified by:

apply in interface it.unimi.dsi.fastutil.Function<K,java.lang.Boolean>

Specified by:

apply in interface java.util.function.Function<K,java.lang.Boolean>

size

public int size()

Specified by:

size in interface it.unimi.dsi.fastutil.Function<K,java.lang.Boolean>

defaultReturnValue

public boolean defaultReturnValue()

Description copied from interface: Reference2BooleanFunction

Gets the default return value.

This default implementation just return the default null value of the type (null for objects, 0 for scalars, false for Booleans).

Specified by:

defaultReturnValue in interface Reference2BooleanFunction<K>

Returns:

the current default return value.

defaultReturnValue

public void defaultReturnValue(boolean defRetValue)

Description copied from interface: Reference2BooleanFunction

Sets the default return value (optional operation). This value must be returned by type-specific versions of get(), put() and remove() to denote that the map does not contain the specified key. It must be 0/false/null by default.

Specified by:

defaultReturnValue in interface Reference2BooleanFunction<K>

Parameters:

defRetValue - the new default return value.

See Also:

Reference2BooleanFunction.defaultReturnValue()

containsKey

public boolean containsKey(java.lang.Object k)

Specified by:

containsKey in interface it.unimi.dsi.fastutil.Function<K,java.lang.Boolean>

put

public boolean put(K k,
boolean v)

Description copied from interface: Reference2BooleanFunction

Adds a pair to the map (optional operation).

Specified by:

put in interface Reference2BooleanFunction<K>

Parameters:

k - the key.

v - the value.

Returns:

the old value, or the default return value if no value was present for the given key.

See Also:

Function.put(Object,Object)

getBoolean

public boolean getBoolean(java.lang.Object k)

Description copied from interface: Reference2BooleanFunction

Returns the value to which the given key is mapped.

Specified by:

getBoolean in interface Reference2BooleanFunction<K>

Parameters:

k - the key.

Returns:

the corresponding value, or the default return value if no value was present for the given key.

See Also:

Function.get(Object)

getOrDefault

public boolean getOrDefault(java.lang.Object k,
boolean defaultValue)

Description copied from interface: Reference2BooleanFunction

Returns the value associated by this function to the specified key, or give the specified value if not present.

Specified by:

getOrDefault in interface Reference2BooleanFunction<K>

Parameters:

k - the key.

defaultValue - the value to return if not present.

Returns:

the corresponding value, or defaultValue if no value was present for the given key.

See Also:

Function.getOrDefault(Object, Object)

removeBoolean

public boolean removeBoolean(java.lang.Object k)

Description copied from interface: Reference2BooleanFunction

Removes the mapping with the given key (optional operation).

Specified by:

removeBoolean in interface Reference2BooleanFunction<K>

Parameters:

k - the key.

Returns:

the old value, or the default return value if no value was present for the given key.

See Also:

Function.remove(Object)
