java.lang.Objectcern.colt.PersistentObject
cern.colt.map.AbstractMap
cern.colt.map.AbstractDoubleIntMap
Abstract base class for hash maps holding (key,value) associations of type (double-->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(DoubleProcedure).
As such they are fully functional, but inefficient. Override them in subclasses if necessary.

abstract boolean |
removeKey(double 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. |

public boolean containsKey(double key)
public boolean containsValue(int value)
public AbstractDoubleIntMap copy()
clone() and casts the result.
public boolean equals(Object obj)

new DoubleIntProcedure() {
public boolean apply(double key, int value) {
return m2.containsKey(key) && m2.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.
obj - object to be compared for equality with this map.
public abstract boolean forEachKey(DoubleProcedure procedure)
procedure - the procedure to be applied. Stops iteration if the procedure returns false, otherwise continues.
public boolean forEachPair(DoubleIntProcedure procedure)
forEachKey(DoubleProcedure).
procedure - the procedure to be applied. Stops iteration if the procedure returns false, otherwise continues.
public abstract int get(double key)
containsKey(double) 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 double 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(DoubleProcedure).
value - the value to search for.
public DoubleArrayList keys()
forEachKey(DoubleProcedure).
This method can be used to iterate over the keys of the receiver.
public void keys(DoubleArrayList list)
forEachKey(DoubleProcedure).
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(DoubleArrayList 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(DoubleIntProcedure condition,
DoubleArrayList keyList,
IntArrayList valueList)
forEachKey(DoubleProcedure).
Example:
DoubleIntProcedure condition = new DoubleIntProcedure() { // match even values only
public boolean apply(double key, int value) { return value%2==0; }
}
keys = (8,7,6), values = (1,2,2) --> keyList = (6,8), valueList = (2,1)
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(DoubleArrayList 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(DoubleArrayList 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(double key,
int value)
key - the key the value shall be associated with.value - the value to be associated.
public abstract boolean removeKey(double key)
key - the key to be removed from the receiver.
public String toString()
public String toStringByValue()
public IntArrayList values()
forEachKey(DoubleProcedure).
This method can be used to iterate over the values of the receiver.
public void values(IntArrayList list)
forEachKey(DoubleProcedure).
This method can be used to iterate over the values of the receiver.
list - the list to be filled, can have any size.
