Objects (Language)

Structure of 4D language objects

The commands of the Objects (Language) theme create and work with data in object form. This extends the exchange opportunities between 4D and any application that supports structured data.

All the commands in this theme support the following 4D objects:

Object variables or object arrays created and initialized using the C_OBJECT ("Compiler" theme) or ARRAY OBJECT ("Arrays" theme) commands.
Object fields from the 4D database (see 4D field types).

For more information on the structure of "native" 4D objects, please refer to the paragraph in the RELATE MANY section.
