RectangularRepeatingElement[elem]

represents a rectangular array of elements of type spec in an interpreter, API or form specification.

RectangularRepeatingElement[elem,{maxrows,maxcolumns}]

represents a rectangular array of elements of maximum size maxrows×maxcolums.

RectangularRepeatingElement[elem,{{minrows,maxrows},{mincolumns,maxcolumns}}]

represents a rectangular array of elements of dimensions between minrows×mincolumns and maxrows×maxcolums.

Basic Examples  (3)

Use RectangularRepeatingElement to interpret a matrix of data:

Wolfram Language code: Interpreter[RectangularRepeatingElement["Number"]][{{"1", "2.5", "3.2"}, {"11", "15", "12.2"}}]

RectangularRepeatingElement fails on data that is not rectangular:

Wolfram Language code: Interpreter[RectangularRepeatingElement["Number"]][{{"1", "2.5", "3.2"}, {"15", "12.2"}}]

Use it in an APIFunction to collect complex data:

Wolfram Language code: api = CloudDeploy @ APIFunction[ "data" -> RectangularRepeatingElement["Integer"], NullSpace[#data]&, AllowedCloudParameterExtensions -> {"json"} ]
Wolfram Language code: URLExecute[api, {"data__json" -> "[[1, 2], [2, 4]]"}]

Scope  (2)

The second argument is used to limit the size of the input:

Wolfram Language code: Interpreter[RectangularRepeatingElement["Integer", {2, 1}]][{{"1", "2", "3"}}]
Wolfram Language code: Interpreter[RectangularRepeatingElement["Integer", {2, 1}]][{{"1"}, {"2"}}]

Limit the minimum size of the array:

Wolfram Language code: Interpreter[RectangularRepeatingElement["Integer", {{2, 100}, {2, 100}}]][{{"1", "2", "3"}}]
Wolfram Language code: Interpreter[RectangularRepeatingElement["Integer", {{2, 100}, {2, 100}}]][{{"1", "2"}, {"3", "4"}}]

Properties & Relations  (3)

RectangularRepeatingElement can be used in conjunction with any interpreter specification:

Wolfram Language code: Interpreter[RectangularRepeatingElement["Integer" | "Country"]][{{"1", "italy"}, {"armenia", "5"}}]

Including RepeatingElement:

Wolfram Language code: Interpreter[RectangularRepeatingElement[RepeatingElement["Number"]]][{{{"1", "2", "3"}, {"1"}}, {{"5", "6"}, {"7"}}}]

And CompoundElement:

Wolfram Language code: Interpreter[RectangularRepeatingElement[CompoundElement[<|"country" -> "Country", "city" -> "City"|>]]][{{<|"country" -> "angola", "city" -> "lahore"|>, <|"city" -> "bangkok", "country" -> "canada"|>}}]

Possible Issues  (1)

Constructs like FormFunction and FormPage do not show a special interface for RectangularRepeatingElement:

Wolfram Language code: CloudDeploy[ FormFunction["data" -> RectangularRepeatingElement["Integer"], NullSpace[#data]& ]]
