Datatypes

Data types are the lowest layer of the data model hierarchy. They are re-usable types used by the components.

• Angle: Angle in either radians or degrees.
• AnnotationInfo: Annotation info annotating a class id or key-point id.
• Blob: A binary blob of data.
• Bool: A single boolean.
• ClassDescription: The description of a semantic Class.
• ClassDescriptionMapElem: A helper type for mapping datatypes.ClassIds to class descriptions.
• ClassId: A 16-bit ID representing a type of semantic class.
• EntityPath: A path to an entity in the ChunkStore.
• Float32: A single-precision 32-bit IEEE 754 floating point number.
• Float64: A double-precision 64-bit IEEE 754 floating point number.
• KeypointId: A 16-bit ID representing a type of semantic keypoint within a class.
• KeypointPair: A connection between two datatypes.KeypointIds.
• Mat3x3: A 3x3 Matrix.

• TimeRange: Visible time range bounds for a specific timeline.
• TimeRangeBoundary: Left or right boundary of a time range.
• Transform3D: Representation of a 3D affine transform.
• TranslationAndMat3x3: Representation of an affine transform via a 3x3 affine matrix paired with a translation.
• TranslationRotationScale3D: Representation of an affine transform via separate translation, rotation & scale.
• UInt32: A 32bit unsigned integer.
• UInt64: A 64bit unsigned integer.
• UVec2D: A uint32 vector in 2D space.
