Function ValidateFilters

internal/validation/validation.go:60–70

ValidateFilters checks if both provided filters, tupleFilter and attributeFilter, are empty. It returns an error if both filters are empty, as at least one filter should contain criteria for the operation to be valid.

(tupleFilter *base.TupleFilter, attributeFilter *base.AttributeFilter)

// ValidateAttribute checks whether a given attribute request (reqAttribute) aligns with
