Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Members

	Name	Description
	Add	Adds new member name-value pair to the member collection. Returns E_FAIL if duplicate member is found.
	AddBoolean	Adds new member name-value pair to the member collection. Returns E_FAIL if duplicate member is found.
	AddDate	Adds new member name-value pair to the member collection. Returns E_FAIL if duplicate member is found.
	AddDouble	Adds new member name-value pair to the member collection. Returns E_FAIL if duplicate member is found.
	AddDoubleEx	Adds new member name-value pair to the member collection. Stores precision for use in ToJSON and ToJSONString. Returns E_FAIL if duplicate member is found.
	AddJSONArray	Adds new member name-value pair to the member collection. Returns E_FAIL if duplicate member is found.
	AddJSONObject	Adds new member name-value pair to the member collection. Returns E_FAIL if duplicate member is found.
	AddLong	Adds new member name-value pair to the member collection. Returns E_FAIL if duplicate member is found.
	AddNull	Adds new member with the value of null to the member collection. Returns E_FAIL if duplicate member is found.
	AddString	Adds new member name-value pair to the member collection. Returns E_FAIL if duplicate member is found.
	CaseSensitiveNames	Returns true if member name lookups are case-sensitive. Default value is true. Methods affected by this state change: MemberExists, IsValueNull and all TryGet... methods.
	ClearAll	Removes all members.
	CreateMemberArray	Creates and adds new member name-value pair to the member collection. Returns E_FAIL if duplicate member is found.
	CreateMemberObject	Creates and adds new member name-value pair to the member collection. Returns E_FAIL if duplicate member is found.
	GetMemberAt	Returns member name and value at a given index.
	IsValueNull	Returns VARIANT_TRUE if member is undefined or member's value is null. Returns VARIANT_FALSE if member exists and its value is not null.
	MakeValueNull	Make a designated member NULL.
	MemberCount	Returns size of member collection.
	MemberExists	Checks if a member with the given name exists.
	ParseJSON	Parses JSON object from IJSONReader into memory. Useful if you want to have random access to just a part of a JSON.
	ParseString	Parses JSON object from string into memory.
	RemoveMember	Remove a member from the member collection.
	ToJSON	Converts IJSONObject to JSON representation using provided IJSONWriter. Useful when you have complex JSON response you want to combine from the output of several methods.
	ToJSONString	Converts IJSONObject to JSON representation using IJSONWriter internally. 'props' parameter is to control IJSONWriter properties. It's safe to set it to NULL.
	TryGetValue	Returns member value for a given name. If member does not exist, returns VARIANT_FALSE in 'success' parameter.
	TryGetValueAsArray	Returns member value for a given name as IJSONArray. If member does not exist or type coercion fails, returns VARIANT_FALSE in 'success' parameter.
	TryGetValueAsBoolean	Returns member value for a given name as boolean. If member does not exist or type coercion fails, returns VARIANT_FALSE in 'success' parameter.
	TryGetValueAsDate	Returns member value for a given name as DATE. If member does not exist or type coercion fails, returns VARIANT_FALSE in 'success' parameter.
	TryGetValueAsDouble	Returns member value for a given name as double. If member does not exist or type coercion fails, returns VARIANT_FALSE in 'success' parameter.
	TryGetValueAsLong	Returns member value for a given name as long. If member does not exist or type coercion fails, returns VARIANT_FALSE in 'success' parameter.
	TryGetValueAsObject	Returns member value for a given name as IJSONObject. If member does not exist or type coercion fails, returns VARIANT_FALSE in 'success' parameter.
	TryGetValueAsString	Returns member value for a given name as string. If member does not exist or type coercion fails, returns VARIANT_FALSE in 'success' parameter.
