MultiDimensional (Property Keyword)

Usage

To specify that this property has the characteristics of a multidimensional array, use the following syntax:

Property Data [ Multidimensional ];

Otherwise, omit this keyword or place the word Not immediately before the keyword.

Details

A multidimensional property is different from other properties as follows:

• InterSystems IRIS does not provide property methods for it (for information on property methods, see Defining and Using Classes).

• It is ignored when the object is validated or saved.

• It is not saved to disk, unless your application includes code to save it specifically.

  That is, the property is also automatically Transient.

• It cannot be exposed to Java or other clients.

• It cannot be stored in or exposed through SQL tables.

Multidimensional properties are rare but provide a useful way to temporarily contain information about the state of an object.
