Function Documentation

◆ UA_HistoryDataBackend_Memory()

UA_HistoryDataBackend UA_HistoryDataBackend_Memory	(	size_t	initialNodeIdStoreSize,
		size_t	initialDataStoreSize
	)

◆ UA_HistoryDataBackend_Memory_Circular()

UA_HistoryDataBackend UA_HistoryDataBackend_Memory_Circular	(	size_t	initialNodeIdStoreSize,
		size_t	initialDataStoreSize
	)

This function construct a UA_HistoryDataBackend which implements a circular buffer in memory.

initialNodeIdStoreSize is the maximum number of NodeIds that will be historized. This number cannot be overcomed. initialDataStoreSize is the maximum number of UA_DataValueMemoryStoreItem that will be saved in the circular buffer for a particular NodeId. Subsequent UA_DataValueMemoryStoreItem will be saved replacing the oldest ones following the logic of circular buffers.

◆ UA_HistoryDataBackend_Memory_clear()

void UA_HistoryDataBackend_Memory_clear ( UA_HistoryDataBackend * backend )
