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

Serialized FormMethod Summary | |
---|---|
void |
assign(AbstractIntLongMap other)
Clears the receiver, then adds all (key,value) pairs of other values to it. |
void |
assign(LongFunction function)
Assigns the result of a function to each value; v[i] = function(v[i]). |
boolean |
containsKey(int key)
Returns true if the receiver contains the specified key. |
boolean |
containsValue(long value)
Returns true if the receiver contains the specified value. |
AbstractIntLongMap |
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(IntProcedure procedure)
Applies a procedure to each key of the receiver, if any. |
boolean |
forEachPair(IntLongProcedure procedure)
Applies a procedure to each (key,value) pair of the receiver, if any. |
abstract long |
get(int key)
Returns the value associated with the specified key. |
int |
keyOf(long value)
Returns the first key the given value is associated with. |
IntArrayList |
keys()
Returns a list filled with all keys contained in the receiver. |
void |
keys(IntArrayList list)
Fills all keys contained in the receiver into the specified list. |
void |
keysSortedByValue(IntArrayList keyList)
Fills all keys sorted ascending by their associated value into the specified list. |
void |
pairsMatching(IntLongProcedure condition,
IntArrayList keyList,
LongArrayList valueList)
Fills all pairs satisfying a given condition into the specified lists. |
void |
pairsSortedByKey(IntArrayList keyList,
LongArrayList valueList)
Fills all keys and values sorted ascending by key into the specified lists. |
void |
pairsSortedByValue(IntArrayList keyList,
LongArrayList valueList)
Fills all keys and values sorted ascending by value into the specified lists. |
abstract boolean |
put(int key,
long value)
Associates the given key with the given value. |
abstract boolean |
removeKey(int 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. |
LongArrayList |
values()
Returns a list filled with all values contained in the receiver. |
void |
values(LongArrayList list)
Fills all values contained in the receiver into the specified list. |

Method Detail |

public void assign(LongFunction function)
function
- a function object taking as argument the current association's
value.public void assign(AbstractIntLongMap other)
other
- the other map to be copied into the receiver.public boolean containsKey(int key)
public boolean containsValue(long value)
public AbstractIntLongMap copy()
clone()
and casts
the result.
public boolean equals(Object obj)
m1.forEachPair( new IntLongProcedure() { public boolean apply(long key, long value) { return m2.containsKey(key) && m2.get(key) == value; } } ) && m2.forEachPair( new IntLongProcedure() { public boolean apply(long key, long 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(IntProcedure procedure)
procedure
- the procedure to be applied. Stops iteration if the procedure
returns false, otherwise continues.
public boolean forEachPair(IntLongProcedure procedure)
forEachKey(IntProcedure)
.
procedure
- the procedure to be applied. Stops iteration if the procedure
returns false, otherwise continues.
public abstract long get(int key)
containsKey(int)
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 int keyOf(long value)
containsValue(long)
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(IntProcedure)
.
value
- the value to search for.
public IntArrayList keys()
forEachKey(IntProcedure)
.
This method can be used to iterate over the keys of the receiver.
public void keys(IntArrayList list)
forEachKey(IntProcedure)
.
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(IntArrayList 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(IntLongProcedure condition, IntArrayList keyList, LongArrayList valueList)
forEachKey(IntProcedure)
.
Example:
IntLongProcedure condition = new IntLongProcedure() { // match even keys only public boolean apply(long key, long value) { return key%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(IntArrayList keyList, LongArrayList 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(IntArrayList keyList, LongArrayList 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(int key, long value)
key
- the key the value shall be associated with.value
- the value to be associated.
public abstract boolean removeKey(int key)
key
- the key to be removed from the receiver.
public String toString()
toString
in class Object
public String toStringByValue()
public LongArrayList values()
forEachKey(IntProcedure)
.
This method can be used to iterate over the values of the receiver.
public void values(LongArrayList list)
forEachKey(IntProcedure)
