UA Base Library Classes
[UA Base Library]
Collaboration diagram for UA Base Library Classes:
|
Classes | |
| class | UaStatusCode |
| The class encapsulated OPC UA status codes and conversions from ant to Classic OPC codes. More... | |
| class | UaStatus |
| The class UaStatus handles status codes, conversions of the status code and diagnostic information. Der ived from UaStatusCode. More... | |
| class | UaDiagnosticInfo |
| The class UaDiagnosticInfo contains the diagnostic information in full format. It is not possible to create plane copies of this Class. More... | |
| class | UaAnnotation |
| Wrapper classs for the ua stack structure OpcUa_Annotation. More... | |
| class | UaArgument |
| Wrapper classs for the ua stack structure OpcUa_Argument. Derived from OpcUa_Argument. More... | |
| class | UaByteArray |
| The UaByteArray handles the access to an array of bytes. UaByteArray can be used to store both raw bytes (including \0s) and traditional 8-bit \0-terminated strings. Using UaByteArray is much more convenient than using const char *. Behind the scenes, it always ensures that the data is followed by a \0 terminator, and uses implicit sharing (copy-on-write) to reduce memory usage and avoid needless copying of data. You don't need to care about resizing or cleaning up the memory. More... | |
| class | UaByteString |
| Wrapper classs for the ua stack structure OpcUa_ByteString. Derived from OpcUa_ByteString. More... | |
| class | UaChar |
| Helper class for modifying UaChar elements. The UaChar class provides a 16-bit Unicode character. It is lightweight, so it can be used everywhere. More... | |
| class | UaDataValue |
| class | UaDateTime |
| Wrapper classs for the ua stack structure OpcUa_DateTime. Helper class for modifying UaDateTime elements. The UaDateTime class provides date and time functions. More... | |
| class | UaBuildInfo |
| Wrapper classs for the ua stack structure OpcUa_BuildInfo. More... | |
| class | UaServerStatusDataType |
| Wrapper classs for the ua stack structure OpcUa_ServerStatusDataType. More... | |
| class | UaRedundantServerDataType |
| Wrapper classs for the ua stack structure OpcUa_RedundantServerDataType. More... | |
| class | UaEUInformation |
| Wrapper classs for the ua stack structure OpcUa_EUInformation. More... | |
| class | UaEventFilter |
| class | UaEventFilterResult |
| class | UaExpandedNodeId |
| Wrapper classs for the ua stack structure OpcUa_ExpandedNodeId. More... | |
| class | UaGuid |
| Wrapper classs for the ua stack structure OpcUa_Guid. Helper class for modifying UaGuid elements. The UaGuid class stores a Global Unique Identifier (GUID). Using Globally Unique IDentifiers is a standard way to globally identify entities in a distributed computing environment. Derived from OpcUa_Guid. More... | |
| class | UaLocalizedText |
| Wrapper classs for the ua stack structure OpcUa_LocalizedText. More... | |
| class | UaMutex |
| The UaMutex class provides access serialization between threads. The purpose of a UaMutex is to protect an object, data structure or section of code so that only one thread can access it at a time (this is similar to the Java synchronized keyword). It is usually best to use a mutex with a UaMutexLocker since this makes it easy to ensure that locking and unlocking are performed consistently. It is not possible to create plane copies of this Class. More... | |
| class | UaNetworkBrowseResult |
| class | UaNetworkBrowser |
| class | UaObjectAttributes |
| Wrapper classs for the ua stack structure OpcUa_ObjectAttributes. More... | |
| class | UaVariableAttributes |
| Wrapper classs for the ua stack structure OpcUa_VariableAttributes. More... | |
| class | UaMethodAttributes |
| Wrapper classs for the ua stack structure OpcUa_MethodAttributes. More... | |
| class | UaObjectTypeAttributes |
| Wrapper classs for the ua stack structure OpcUa_ObjectTypeAttributes. More... | |
| class | UaVariableTypeAttributes |
| Wrapper classs for the ua stack structure OpcUa_VariableTypeAttributes. More... | |
| class | UaReferenceTypeAttributes |
| Wrapper classs for the ua stack structure OpcUa_ReferenceTypeAttributes. More... | |
| class | UaDataTypeAttributes |
| Wrapper classs for the ua stack structure OpcUa_DataTypeAttributes. More... | |
| class | UaViewAttributes |
| Wrapper classs for the ua stack structure OpcUa_ViewAttributes. More... | |
| class | UaNodeId |
| This class encapsulates the native OpcUa_NodeId structure and handles memory allocation and cleanup for you. UaNodeId uses implicit sharing to avoid needless copying and to boost the performance. Only if you modify a shared NodeId it creates a copy for that (copy-on-write). So assigning another UaNodeId or passing it as parameter is as fast as assigning a pointer. More... | |
| class | UaNumericRange |
| class | UaPkiProvider |
| Wrapper classs for a PKI provider. The core library implements the basic cryptographic functions and provides various utility functions. It is not possible to create plane copies of this Class. It is not possible to use the default constructor. More... | |
| class | UaPkiProviderNoSecurity |
| Wrapper classs for no security PKI provider. More... | |
| class | UaPlatformLayer |
| Platform layer handling class. More... | |
| class | UaQualifiedName |
| Wrapper classs for the ua stack structure OpcUa_QualifiedName. Qualified names are two-part names: namespaceindex (UInt16) and name (String). The name part of QualifiedNames is restricted to 512 characters. Derived from OpcUa_QualifiedName. More... | |
| class | UaRange |
| Wrapper classs for the ua stack structure OpcUa_Range. More... | |
| class | UaSemaphore |
| Semaphore class is used to allow threads to synchronize access to a resource. The UaSemaphore class provides a general counting semaphore. A semaphore is a generalization of a mutex. While a mutex can only be locked once, it's possible to acquire a semaphore multiple times. Semaphores are typically used to protect a certain number of identical resources. A typical application of semaphores is for controlling access to a circular buffer shared by a producer thread and a consumer thread. It is not possible to create plane copies of this Class. It is not possible to use the default constructor. More... | |
| class | UaSettings |
| class | UaSettingsSection |
| class | UaString |
| This class encapsulates the native OpcUa_String structure and handles memory allocation and cleanup for you. Additionally you can extract native UTF-8 (char*) strings or UTF-16 (ushort*) strings for further processing in other applications. UaString uses implicit sharing to avoid needless copying and to boost the performance. Only if you modify a shared string it creates a copy for that (copy-on-write). So assigning another UaString or passing it as parameter needs constant time is nearly as fast as assigning a pointer. More... | |
| class | UaThread |
| Platfrom independent classs for thread creation. A UaThreads represents a separate thread of control within the program; it shares data with all the other threads within the process but executes independently in the way that a separate program does on a multitasking operating system. Instead of starting in main(), UaThreads begin executing in run(). It is not possible to create plane copies of this Class. More... | |
| class | UaThreadPoolJob |
| class | UaThreadPool |
| class | UaTrace |
| class | UaVariant |
| Portable Ua Variant class. Converts Variant into all datatypes. The UaVariant class acts like a union for the most common Ua data types. More... | |
| class | UaVariantException |
| UaVariantException Class. More... | |
