- true to collect comment and allow writing them

|
|
This parameter is ignored if allowComments is false.
|
|
- `"allowComments": false or true`
|
|
- true if comments are allowed.
|
|
- `"strictRoot": false or true`
|
|
- true if root must be either an array or an object value
|
|
- `"allowDroppedNullPlaceholders": false or true`
|
|
- true if dropped null placeholders are allowed. (See StreamWriterBuilder.)
|
|
- `"allowNumericKeys": false or true`
|
|
- true if numeric object keys are allowed.
|
|
- `"allowSingleQuotes": false or true`
|
|
- true if '' are allowed for strings (both keys and values)
|
|
- `"stackLimit": integer`
|
|
- Exceeding stackLimit (recursive depth of `readValue()`) will
|
|
cause an exception.
|
|
- This is a security issue (seg-faults caused by deeply nested JSON),
|
|
so the default is low.
|
|
- `"failIfExtra": false or true`
|
|
- If true, `parse()` returns false when extra non-whitespace trails
|
|
the JSON value in the input string.
|
|
- `"rejectDupKeys": false or true`
|
|
- If true, `parse()` returns false when a key is duplicated within an object.
|
|
- `"allowSpecialFloats": false or true`
|
|
- If true, special float values (NaNs and infinities) are allowed
|
|
and their values are lossfree restorable.
