类 ConcurrentCountingMap<T>

java.lang.Object

soot.jimple.infoflow.collect.ConcurrentCountingMap<T>

所有已实现的接口:

ConcurrentMap<T,Integer>, Map<T,Integer>

public class ConcurrentCountingMap<T>
extends Object
implements ConcurrentMap<T,Integer>

A map that associates an element with a number. This map will never return a null value, but will pre-initialize all counters with a default value of zero.

increment

public int increment(T key)

Increments the counter associated with the given value by one

参数:

key - The key of the value for which to increment the counter

返回:

The new counter value

increment

public int increment(T key,
                     int delta)

Increments the counter associated with the given value by the given delta

参数:

key - The key of the value for which to increment the counter

delta - The delta by which to increment the counter

返回:

The new counter value

decrement

public int decrement(T key)

Decrements the counter associated with the given value by one

参数:

key - The key of the value for which to decrement the counter

返回:

The new counter value

getByValue

public Set<T> getByValue(int value)

Gets all keys that have the given value. Note that values are free to change at any time, so the set returned by this method may contain keys that have other values as well in case they were mutated by a different thread while this method was running.

参数:

value - The expected value

返回:

A set with all keys that have the given value

setLockingMode

public void setLockingMode(ConcurrentCountingMap.LockingMode lockingMode)

Sets how whether and how this class shall perform locking

参数:

lockingMode - The new locking mode

snapshot

public ConcurrentCountingMap<T> snapshot()

Creates a snapshot of this map

返回:

A copy of the current state of this map

snapshot

public ConcurrentCountingMap<T> snapshot(Collection<T> subset)

Creates a partial snapshot of this map

参数:

subset - The subset of element for which to create a partial snapshot

返回:

A copy of the current state of this map

getChangeCounter

public int getChangeCounter()

Gets the current state of the change counter. This counter is modified whenever the contents of the map are changed.

返回:

The current value of the change counter
