Importing
17 Feb 202215 minutes to read
Importing allows you to view or edit the predefined conditions. You can import the conditions by using methods and initial rendering.
Initial Rendering
To apply conditions initially, you can define the Rule. Here, you can import structured JSON object by defining the Rule property.

Import from JSON
You can set the conditions from structured JSON object through the setRules method.

}Exporting
Exporting allows you to save or maintain the created conditions through the Query Builder. You can export the defined conditions by the following ways.
JSON Export
You can export the defined conditions to structured JSON object through the getRules method.
SQL Support
You can export the defined conditions to SQL query through the getRulesFromSQL method.
