vvOut a internal DS

[Dan]

is there an easy way to send a multi-occurence DataStructure which has multiple subfields in it? For example, using vvOut_xxx or sth, instead of building the complete JSON string myself.

The following 2 ways in vvOut_toJSON has limitations:

By specifying vvOut.object, it only works if the DS is vvTreeDS or refers to a external defined file.

or

By specifying vvOut.fieldxxxxx, it only works with an array (which contain only 1 field).


Thanks,
Dan

Hi Dan -

Could you elaborate a little further on this? Are you attempting to send a multi-dimensional array to the front-end (arrays within arrays) or do you want to send multiple "roots" at the same time?

Hello, Sean.

I want to be able to send out a json response similar to what you can do to send out multiple records in a physical file using vvOut_toJSON. Difference is: the data won't be from a physical file, but from an "Array Data Structure" (defined in the program NOT using "LIKEREC", and loaded at run time).


Thanks,
Dan

In that case, you would need to build the JSON string yourself. You could use vvOut_buffer to build the string within your program as this will store everything until you are ready to send it out.
