BridgeAbstract implements helper methods to make it easier for bridge maintainers to create bridges. Use these methods whenever possible instead of writing your own.
Within the context of the current bridge, stores a value by key in the cache. The value can later be retrieved with loadCacheValue.
+protected function saveCacheValue($key, $value)
+$key - the name under which the value is stored in the cache.$value - the value to store in the cache.Usage example:
+const MY_KEY = 'MyKey';
+
+public function collectData()
+{
+ $value = 'my value';
+ $this->saveCacheValue(MY_KEY, $value);
+}
+Within the context of the current bridge, loads a value by key from cache. Optionally specifies the cache duration for the key. Returns null if the key doesn’t exist or the value is expired.
protected function loadCacheValue($key, $duration = 86400)
+$key - the name under which the value is stored in the cache.$duration - the maximum time in seconds after which the value expires. The default duration is 86400 (24 hours).Usage example:
+const MY_KEY = 'MyKey';
+
+public function collectData()
+{
+ $value = $this->loadCacheValue(MY_KEY, 1800 /* 30 minutes */);
+
+ if (!isset($value)){
+ // load value
+ $this->saveCacheValue(MY_KEY, $value);
+ }
+
+ // ...
+}
