Detailed Description

Object for constructing IDimensionExpr.

There is no public way to construct an IExprBuilder. It appears as an argument to method IPluginV2DynamicExt::getOutputDimensions(). Overrides of that method can use that IExprBuilder argument to construct expressions that define output dimensions in terms of input dimensions.

Clients should assume that any values constructed by the IExprBuilder are destroyed after IPluginV2DynamicExt::getOutputDimensions() returns.

Warning: Do not inherit from this class, as doing so will break forward-compatibility of the API and ABI.

◆ constant()

virtual const IDimensionExpr* nvinfer1::IExprBuilder::constant ( int32_t value )

pure virtual

Return pointer to IDimensionExp for given value.

Here is the caller graph for this function:

◆ operation()

virtual const IDimensionExpr* nvinfer1::IExprBuilder::operation	(	DimensionOperation	op,
		const IDimensionExpr &	first,
		const IDimensionExpr &	second
	)

pure virtual

Return pointer to IDimensionExp that represents the given operation applied to first and second.

Returns nullptr if op is not a valid DimensionOperation.
