Method Details

jsonToObjectArray

public static Object[][] jsonToObjectArray(String json,
 boolean addOptionsAfterValue)

Converts a flat JSON object into a two-dimensional Object[][] array.

Supports JSON keys with up to two options separated by ':'. The resulting row may contain 2–4 elements.

Each JSON entry is converted into one row of the resulting array:

• {"key": value} → {"key", convertedValue}
• {"key:OPTION": value} →
  • if addOptionsAfterValue == true → {"key", convertedValue, "OPTION"}
  • if addOptionsAfterValue == false → {"key", "OPTION", convertedValue}

Value conversion rules:

• JSON number (int/long) → Integer/Long
• JSON decimal → String
• JSON string → String
• JSON boolean → Boolean
• JSON null → null
• JSON object or array → compact JSON String

Parameters:

json - the JSON string representing a flat object

addOptionsAfterValue - controls the order of elements when a key contains options separated by ':'. If true, the order is key, value, option. If false, the order is key, option, value.

Returns:

a two-dimensional Object[][] representation of the JSON object

Throws:

QueryBuilderException - if the provided JSON is not a flat JSON object or parsing/conversion fails
