Type Configuration

Type Configuration

A type configuration is a set of complex port properties that specify the data type of the complex data type elements or the schema of the data. After you create a complex port, you specify or change the type configuration for the complex port on the Ports tab.
The type configuration for a complex port depends on the complex data type assigned to the port. You must specify a complex data type definition for a struct port or a struct element in a complex port. Array and map ports have a default type configuration that you can change.
The following table lists the type configuration properties for complex ports:
Complex Port
Type Configuration Properties
array
  • Type. Data type of the elements of an array. Default is string.
  • Array Dimension. Number of levels for an array. Default is 1.
  • Precision. Maximum number of significant digits for numeric data types, or maximum number of characters for string data types.
  • Scale. Maximum number of digits after the decimal point of numeric values.
map
  • Type. Data type of the key-value pair. Default is string for key and value.
  • Precision. Maximum number of significant digits for numeric data types, or maximum number of characters for string data types.
  • Scale. Maximum number of digits after the decimal point of numeric values.
struct
  • Complex data type definition. The schema of the data that you created or imported as complex data type definition in the type definition library.
