Enumeration Type Documentation

enum Json::CommentPlacement

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)

Definition at line 52 of file value.h.

enum Json::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).

Definition at line 40 of file value.h.

Function Documentation

std::ostream & Json::operator<<	(	std::ostream &	,
		const Value &	root
	)

Output using the StyledStreamWriter.

See also:

Json::operator>>()

Definition at line 825 of file json_writer.cpp.

std::istream & Json::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:

    Json::Value root;
    cin >> root["dir"]["file"];
    cout << root;

Result:

    {
    "dir": {
        "file": {
        // The input stream JSON would be nested here.
        }
    }
    }
    

Exceptions:

std::exception

on parse error.
