Function isDataFrameArgument

isDataFrameArgument(
arg: undefined | RNode<ParentInformation>,
inference: DataFrameShapeInferenceVisitor,
): arg is RNode<ParentInformation>
Checks if a given argument has an inferred data frame shape and therefore represents a data frame
Parameters
- arg: undefined | RNode<ParentInformation>
  The argument to check
- inference: DataFrameShapeInferenceVisitor
  The data frame shape inference visitor to use
Returns arg is RNode<ParentInformation>
Whether the argument represents a data frame
- Defined in src/abstract-interpretation/data-frame/mappers/arguments.ts:224
isDataFrameArgument(
arg: undefined | RFunctionArgument<ParentInformation>,
inference: DataFrameShapeInferenceVisitor,
): arg is RArgument<ParentInformation> & { value: RNode<ParentInformation> }
Checks if a given argument has an inferred data frame shape and therefore represents a data frame
Parameters
- arg: undefined | RFunctionArgument<ParentInformation>
  The argument to check
- inference: DataFrameShapeInferenceVisitor
  The data frame shape inference visitor to use
Returns arg is RArgument<ParentInformation> & { value: RNode<ParentInformation> }
Whether the argument represents a data frame
- Defined in src/abstract-interpretation/data-frame/mappers/arguments.ts:226
