Enumerator
uintToStringBufferSize 

Constant that specify the size of the buffer that must be passed to uintToString.

Enumerator
commentBefore 

a comment placed on the line before a value

commentAfterOnSameLine 

a comment just after a value on the same line

commentAfter 

a comment on the line after a value (only make sense for root value)

numberOfCommentPlacement 
enum ValueType

Type of the value held by a Value object.

Enumerator
nullValue 

'null' value

intValue 

signed integer value

uintValue 

unsigned integer value

realValue 

double value

stringValue 

UTF-8 string value.

booleanValue 

bool value

arrayValue 

array value (ordered list)

objectValue 

object value (collection of name/value pairs).

Output using the StyledStreamWriter.

CSJson::operator>>()
std::istream& CSJson::operator>> ( std::istream &  ,
Value &   
)

Read from 'sin' into 'root'.

Always keep comments from the input JSON.

This can be used to read a file into a particular sub-object. For example:

cin >> root["dir"]["file"];
cout << root;

Result:

{
"dir": {
    "file": {
    // The input stream JSON would be nested here.
    }
}
}
Exceptions
std::exceptionon parse error.
