Serializes a FoxPro value to a JSON string. Supports all VFP basic types, most complex objects (as long as there are no circular references), simple arrays and collections and cursors.

To serialize simple values:

ltToday = DateTime()
loSerializer = CREATEOBJECT("wwJsonSerializer")
lcJSON = loSerializer.Serialize(ltToday)

To serialize an object:

*** Serialize an object (single or nested hierarchy)
SELECT Customer
SCATTER NAME loCustomer 
lcJSON=loSerializer.Serialize(loCustomer)

Cursors serialize like an array of object with a root node call Rows and an array of each row as an object.

Since cursors cannot be passed as a value to the Serialize() function special syntax is used:

cursor:<AliasName>

To serialize a FoxPro cursor or table:

select * from tt_cust into TCustomers
loSerializer = CREATEOBJECT("wwJsonSerializer")
lcJSON = loSerializer.Serialize("cursor:TCustomers")

o.Serialize(lvValue)

Return Value

Serialized JSON string

Parameters

lvValue
