#include <coherence/util/WeakHashMap.hpp>
A map entry (key-value pair).
The Map.entrySet method returns a collection-view of the map, whose elements are of this class.
The stored key is always a WeakReference to the user supplied key.
Public Types |

| typedef spec::Handle | Handle |
| Entry Handle definition. | |
| typedef spec::View | View |
| Entry View definition. | |
| typedef spec::Holder | Holder |
| Entry Holder definition. | |
Public Member Functions |
|
| virtual bool | isValid () const |
| Return true the entry references a key which is still valid, i.e. | |
| virtual Object::View | getKey () const |
Protected Member Functions |
|
| Entry (Object::View vKey, Object::Holder ohValue, size32_t nHash) | |
| Construct a thread-safe weak hash map using the specified settings. | |
| Entry (const Entry &that) | |
| Copy constructor. | |
| Entry (Entry::View vThat) | |
| Copy an Entry. | |
| virtual bool | isKeyEqual (Object::View vKey) const |
| Entry | ( | Object::View | vKey, | |
| Object::Holder | ohValue, | |||
| size32_t | nHash | |||
| ) | [protected] |
Construct a thread-safe weak hash map using the specified settings.
| cInitialBuckets | the initial number of hash buckets, 0 < n | |
| flLoadFactor | the acceptable load factor before resizing occurs, 0 < n, such that a load factor of 1.0 causes resizing when the number of entries exceeds the number of buckets | |
| flGrowthRate | the rate of bucket growth when a resize occurs, 0 < n, such that a growth rate of 1.0 will double the number of buckets: bucketcount = bucketcount * (1 + growthrate) |
| Entry | ( | Entry::View | vThat | ) | [protected] |
Copy an Entry.
| vThat | the entry to copy |
| virtual bool isValid | ( | ) | const [virtual] |
Return true the entry references a key which is still valid, i.e.
has not been reclaimed.
