SharedQueueFactoryBase (FB) ¶ FUNCTION_BLOCK PUBLIC SharedQueueFactoryBase EXTENDS FBF.FactoryBase This is a base implementation of a factory for SharedQueue instances. Please extend this function block and implement the prvInstPoolAdr property for realizing a factory based on static memory. The default implementation results in a heap memory based factory with a initial capacity of 5 ( prvInstCount := 5 ). Overwriting prvInstCount provides the possibility to control the initial capacity of the pool. Implementing prvInstPoolExtendsFactor provides the possibility to control the dynmic extension of the pool. prvInstPoolExtendsFactor = 0 => No possibility for extending the pool. prvInstPoolExtendsFactor > 0 => Extendion of the pool will be possible. A value of e.g. prvInstPoolExtendsFactor := 50 always expands the pool by 50% of its original size.
