Method Detail

Removes a key recursively from anywhere in a JSON document. NOTE: mutates its input.

Parameters:

json - the Jackson Object version of the JSON document (contents changed by this call)

keyToRemove - the key to remove from the document

javason

public static Map<String,Object> javason(String javason)
                                  throws IOException

Utility for test classes, so that they can inline json in a test class. Does a character level replacement of apostrophe (') with double quote ("). This means you can express a snippit of Json without having to forward slash escape everything. This is character based, so don't have any apostrophes (') in your test data.

Parameters:

javason - Json-ish string you want to turn into Maps-of-Maps

Returns:

Maps-of-Maps

Throws:

IOException
