Namespace List

Here is a list of all namespaces with brief descriptions:

[detail level 123]

▼NOrt	All C++ Onnxruntime APIs are defined inside this namespace
▼Ndetail
Nattr_utils
Nbinding_utils
CAllocatedFree
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
CConstValueImpl
CIoBindingImpl
CMapTypeInfoImpl
CMemoryInfoImpl
COptionalTypeInfoImpl
COrtSparseValuesParam
CSequenceTypeInfoImpl
CSessionImpl
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
CCheckpointState	Holds the state of the training session
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
CFloat8E4M3FN_t	Float8e4m3fn (Float8 Floating Point) data type
CFloat8E4M3FNUZ_t	Float8e4m3fnuz (Float8 Floating Point) data type
CFloat8E5M2_t	Float8e5m2 (Float8 Floating Point) data type
CFloat8E5M2FNUZ_t	Float8e5m2fnuz (Float8 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
CLogger	This class represents an ONNX Runtime logger that can be used to log information with an associated severity level and source code location (file path, line number, function name)
CLoraAdapter	LoraAdapter holds a set of Lora Parameters loaded from a single file
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
▼CShapeInferContext	Provide access to per-node attributes and input shapes, so one could compute and set output shapes
CSymbolicInteger
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
CTrainingSession	Trainer class that provides training, evaluation and optimizer methods for training an ONNX models
CTypeInfo	Type information that may contain either TensorTypeAndShapeInfo or the information about contained sequence or map depending on the ONNXType
CValue	Wrapper around OrtValue
