cern.colt.map.tfloat.AbstractFloatIntMap
public abstract class AbstractFloatIntMap
Abstract base class for hash maps holding (key,value) associations of type (float-->int). First see the package summary and javadoc tree view to get the broad picture.
Implementation:
Almost all methods are expressed in terms of
forEachKey(FloatProcedure)
. As such they are fully functional, but
inefficient. Override them in subclasses if necessary.

Serialized FormMethod Summary | |
---|---|
boolean |
containsKey(float key)
Returns true if the receiver contains the specified key. |
boolean |
containsValue(int value)
Returns true if the receiver contains the specified value. |
AbstractFloatIntMap |
copy()
Returns a deep copy of the receiver; uses clone() and casts
the result. |
boolean |
equals(Object obj)
Compares the specified object with this map for equality. |
abstract boolean |
forEachKey(FloatProcedure procedure)
Applies a procedure to each key of the receiver, if any. |
boolean |
forEachPair(FloatIntProcedure procedure)
Applies a procedure to each (key,value) pair of the receiver, if any. |
abstract int |
get(float key)
Returns the value associated with the specified key. |
float |
keyOf(int value)
Returns the first key the given value is associated with. |
FloatArrayList |
keys()
Returns a list filled with all keys contained in the receiver. |
void |
keys(FloatArrayList list)
Fills all keys contained in the receiver into the specified list. |
void |
keysSortedByValue(FloatArrayList keyList)
Fills all keys sorted ascending by their associated value into the specified list. |
void |
pairsMatching(FloatIntProcedure condition,
FloatArrayList keyList,
IntArrayList valueList)
Fills all pairs satisfying a given condition into the specified lists. |
void |
pairsSortedByKey(FloatArrayList keyList,
IntArrayList valueList)
Fills all keys and values sorted ascending by key into the specified lists. |
void |
pairsSortedByValue(FloatArrayList keyList,
IntArrayList valueList)
Fills all keys and values sorted ascending by value into the specified lists. |
abstract boolean |
put(float key,
int value)
Associates the given key with the given value. |
abstract boolean |
removeKey(float key)
Removes the given key with its associated element from the receiver, if present. |
String |
toString()
Returns a string representation of the receiver, containing the String representation of each key-value pair, sorted ascending by key. |
String |
toStringByValue()
Returns a string representation of the receiver, containing the String representation of each key-value pair, sorted ascending by value. |
IntArrayList |
values()
Returns a list filled with all values contained in the receiver. |
void |
values(IntArrayList list)
Fills all values contained in the receiver into the specified list. |

the result.
public boolean equals(Object obj)
m1.forEachPair( new FloatIntProcedure() { public boolean apply(float key, int value) { return m2.containsKey(key) && m2.get(key) == value; } } ) && m2.forEachPair( new FloatIntProcedure() { public boolean apply(float key, int value) { return m1.containsKey(key) && m1.get(key) == value; } } );This implementation first checks if the specified object is this map; if so it returns true. Then, it checks if the specified object is a map whose size is identical to the size of this set; if not, it it returns false. If so, it applies the iteration as described above.
equals
in class Object
obj
- object to be compared for equality with this map.
public abstract boolean forEachKey(FloatProcedure procedure)
procedure
- the procedure to be applied. Stops iteration if the procedure
returns false, otherwise continues.
public boolean forEachPair(FloatIntProcedure procedure)
forEachKey(FloatProcedure)
.
procedure
- the procedure to be applied. Stops iteration if the procedure
returns false, otherwise continues.
public abstract int get(float key)
containsKey(float)
whether the given
key has a value associated or not, i.e. whether there exists an
association for the given key or not.
key
- the key to be searched for.
public float keyOf(int value)
containsValue(int)
whether there
exists an association from a key to this value. Search order is
guaranteed to be identical to the order used by method
forEachKey(FloatProcedure)
.
value
- the value to search for.
public FloatArrayList keys()
forEachKey(FloatProcedure)
.
This method can be used to iterate over the keys of the receiver.
public void keys(FloatArrayList list)
forEachKey(FloatProcedure)
.
This method can be used to iterate over the keys of the receiver.
list
- the list to be filled, can have any size.public void keysSortedByValue(FloatArrayList keyList)
Example:
keys = (8,7,6), values = (1,2,2) --> keyList = (8,6,7)
keyList
- the list to be filled, can have any size.public void pairsMatching(FloatIntProcedure condition, FloatArrayList keyList, IntArrayList valueList)
forEachKey(FloatProcedure)
.
Example:
FloatIntProcedure condition = new FloatIntProcedure() { // match even values only public boolean apply(float key, int value) { return value%2==0; } } keys = (8,7,6), values = (1,2,2) --> keyList = (6,8), valueList = (2,1) </tt>
condition
- the condition to be matched. Takes the current key as first
and the current value as second argument.keyList
- the list to be filled with keys, can have any size.valueList
- the list to be filled with values, can have any size.public void pairsSortedByKey(FloatArrayList keyList, IntArrayList valueList)
Example:
keys = (8,7,6), values = (1,2,2) --> keyList = (6,7,8), valueList = (2,2,1)
keyList
- the list to be filled with keys, can have any size.valueList
- the list to be filled with values, can have any size.public void pairsSortedByValue(FloatArrayList keyList, IntArrayList valueList)
Example:
keys = (8,7,6), values = (1,2,2) --> keyList = (8,6,7), valueList = (1,2,2)
keyList
- the list to be filled with keys, can have any size.valueList
- the list to be filled with values, can have any size.public abstract boolean put(float key, int value)
key
- the key the value shall be associated with.value
- the value to be associated.
public abstract boolean removeKey(float key)
key
- the key to be removed from the receiver.
public String toString()
toString
