Class List

Here are the classes, structs, unions and interfaces with brief descriptions:

[detail level 123]

▼NOrt	All C++ Onnxruntime APIs are defined inside this namespace
▼Ndetail
CAllocatedFree
CAllocatorImpl
CBase	Used internally by the C++ API. C++ wrapper types inherit from this. This is a zero cost abstraction to wrap the C API objects and delete them on destruction
CBase< Unowned< T > >	Covers unowned pointers owned by either the ORT or some other instance of CPP wrappers. Used for ConstXXX and UnownedXXXX types that are copyable. Also convenient to wrap raw OrtXX pointers
CConstIoBindingImpl
CConstSessionImpl
CConstSessionOptionsImpl
CConstValueImpl
CIoBindingImpl
CKernelInfoImpl
CMapTypeInfoImpl
CMemoryInfoImpl
COrtSparseValuesParam
CSequenceTypeInfoImpl
CSessionImpl
CSessionOptionsImpl
CShape
CTensorTypeAndShapeInfoImpl
CTypeInfoImpl
CUnowned	This is a tagging template type. Use it with Base<T> to indicate that the C++ interface object has no ownership of the underlying C object
CValueImpl
CAllocator	Wrapper around OrtAllocator
CAllocatorWithDefaultOptions	Wrapper around OrtAllocator default instance that is owned by Onnxruntime
CArenaCfg	It is a structure that represents the configuration of an arena based allocator
CBFloat16_t	Bfloat16 (Brain Floating Point) data type
CCustomOpApi	This entire structure is deprecated, but we not marking it as a whole yet since we want to preserve for the next release
CCustomOpBase
CCustomOpConfigs	Class that represents session configuration entries for one or more custom operators
CCustomOpDomain	Custom Op Domain
CEnv	The Env (Environment)
CException	All C++ methods that can fail will throw an exception of this type
CFloat16_t	IEEE 754 half-precision floating point data type
CGlobal
CIoBinding	Wrapper around OrtIoBinding
CKernelContext	This class wraps a raw pointer OrtKernelContext* that is being passed to the custom kernel Compute() method. Use it to safely access context attributes, input and output parameters with exception safety guarantees. See usage example in onnxruntime/test/testdata/custom_op_library/custom_op_library.cc
CKernelInfo	This struct owns the OrtKernInfo* pointer when a copy is made. For convenient wrapping of OrtKernelInfo* passed to kernel constructor and query attributes, warp the pointer with Ort::Unowned<KernelInfo> instance so it does not destroy the pointer the kernel does not own
CMapTypeInfo	Wrapper around OrtMapTypeInfo
CMemoryAllocation	Represents native memory allocation coming from one of the OrtAllocators registered with OnnxRuntime. Use it to wrap an allocation made by an allocator so it can be automatically released when no longer needed
CMemoryInfo	Wrapper around OrtMemoryInfo
CModelMetadata	Wrapper around OrtModelMetadata
COp	Create and own custom defined operation
COpAttr	This struct provides life time management for custom op attribute
CRunOptions	RunOptions
CSequenceTypeInfo	Wrapper around OrtSequenceTypeInfo
CSession	Wrapper around OrtSession
CSessionOptions	Wrapper around OrtSessionOptions
CStatus	The Status that holds ownership of OrtStatus received from C API Use it to safely destroy OrtStatus* returned from the C API. Use appropriate constructors to construct an instance of a Status object from exceptions
CTensorTypeAndShapeInfo	Wrapper around OrtTensorTypeAndShapeInfo
CThreadingOptions	The ThreadingOptions
CTypeInfo	Type information that may contain either TensorTypeAndShapeInfo or the information about contained sequence or map depending on the ONNXType
CValue	Wrapper around OrtValue
COrtAllocator	Memory allocation interface
COrtApi	The C API
COrtApiBase	The helper interface to get the right version of OrtApi
COrtCUDAProviderOptions	CUDA Provider Options
COrtCustomHandleType
COrtCustomOp
COrtMIGraphXProviderOptions	MIGraphX Provider Options
COrtOpenVINOProviderOptions	OpenVINO Provider Options
COrtROCMProviderOptions	ROCM Provider Options
COrtTensorRTProviderOptions	TensorRT Provider Options
