Method Detail

remove

public Object remove(Object ok)

Description copied from class: AbstractDouble2DoubleMap

Delegates to the corresponding type-specific method, taking care of returning null on a missing key.

This method must check whether the provided key is in the map using containsKey(). Thus, it probes the map twice. Implementors of subclasses should override it with a more efficient method.

Specified by:

remove in interface Map

Overrides:

remove in class AbstractDouble2DoubleMap

get

public Object get(Object ok)

Description copied from class: AbstractDouble2DoubleMap

Delegates to the corresponding type-specific method, taking care of returning null on a missing key.

This method must check whether the provided key is in the map using containsKey(). Thus, it probes the map twice. Implementors of subclasses should override it with a more efficient method.

Specified by:

get in interface Map

Overrides:

get in class AbstractDouble2DoubleMap

size

public int size()

Specified by:

size in interface Map

containsKey

public boolean containsKey(double k)

Description copied from class: AbstractDouble2DoubleMap

Checks whether the given value is contained in AbstractDouble2DoubleMap.keySet().

Specified by:

containsKey in interface Double2DoubleMap

Overrides:

containsKey in class AbstractDouble2DoubleMap

containsValue

public boolean containsValue(double v)

Description copied from class: AbstractDouble2DoubleMap

Checks whether the given value is contained in AbstractDouble2DoubleMap.values().

Specified by:

containsValue in interface Double2DoubleMap

Overrides:

containsValue in class AbstractDouble2DoubleMap

defaultReturnValue

public double defaultReturnValue()

Description copied from interface: Double2DoubleMap

Gets the default return value.

Specified by:

defaultReturnValue in interface Double2DoubleMap

Overrides:

defaultReturnValue in class AbstractDouble2DoubleMap

defaultReturnValue

public void defaultReturnValue(double defRetValue)

Description copied from interface: Double2DoubleMap

Sets the default return value. 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 Double2DoubleMap

Overrides:

defaultReturnValue in class AbstractDouble2DoubleMap

put

public double put(double k,
                  double v)

Description copied from interface: Double2DoubleMap

Adds a pair to the map.

Specified by:

put in interface Double2DoubleMap

Overrides:

put in class AbstractDouble2DoubleMap

putAll

public void putAll(Double2DoubleMap c)

entrySet

public Set entrySet()

Specified by:

entrySet in interface Map

keySet

public Set keySet()

Description copied from class: AbstractDouble2DoubleMap

Returns a type-specific-set view of the keys of this map.

The view is backed by the set returned by Map.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.

Specified by:

keySet in interface Map

Overrides:

keySet in class AbstractDouble2DoubleMap

Returns:

a set view of the keys of this map; it may be safely cast to a type-specific interface.

values

public Collection values()

Description copied from class: AbstractDouble2DoubleMap

Returns a type-specific-set view of the values of this map.

The view is backed by the set returned by Map.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.

Specified by:

values in interface Map

Overrides:

values in class AbstractDouble2DoubleMap

Returns:

a set view of the values of this map; it may be safely cast to a type-specific interface.

clear

public void clear()

Specified by:

clear in interface Map

Overrides:

clear in class AbstractDouble2DoubleMap

toString

public String toString()

Overrides:

toString in class AbstractDouble2DoubleMap

put

public Object put(Object k,
                  Object v)

Description copied from class: AbstractDouble2DoubleMap

Delegates to the corresponding type-specific method, taking care of returning null on a missing key.

This method must check whether the provided key is in the map using containsKey(). Thus, it probes the map twice. Implementors of subclasses should override it with a more efficient method.

Specified by:

put in interface Map

Overrides:

put in class AbstractDouble2DoubleMap

remove

public double remove(double k)

Description copied from interface: Double2DoubleMap

Removes the mapping with the given key.

Specified by:

remove in interface Double2DoubleMap

Overrides:

remove in class AbstractDouble2DoubleMap

get

public double get(double k)

Description copied from interface: Double2DoubleMap

Returns the value to which the given key is mapped.

Specified by:

get in interface Double2DoubleMap

Parameters:

k - the key.

Returns:

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

containsKey

public boolean containsKey(Object ok)

Specified by:

containsKey in interface Map

Overrides:

Specified by:

containsValue in interface Map

Overrides:
