LOCAL a
LOCAL oJson
LOCAL oAbc

//  This example requires Chilkat v9.5.0.64 or greater.

//  Loading into a new JSON array is simple and straightforward.
a := CreateObject("Chilkat.JsonArray")
a:Load("[ 1,2,3,4 ]")

//  Output:  [1,2,3,4]
? a:Emit()
? "--------"

//  The JsonArray's Load and LoadSb methods have a peculiar behavior when
//  it is already part of a JSON document.  In this case, the JsonArray
//  becomes detached, and the original document remains unchanged.
//  This is intentional due to the nature of the internal implementation.
//  For example:

oJson := CreateObject("Chilkat.JsonObject")
oJson:Load('{ "abc": [ 1,2,3,4 ] }')

//  Output:  (json) {"abc":[1,2,3,4]}
? "(json) " + oJson:Emit()
? "--------"

oAbc := oJson:ArrayOf("abc")
//  When Load is called, abc becomes it's own document, and the original is not modified.
oAbc:Load("[ 5,6,7,8 ]")

//  Output: (abc) [5,6,7,8]
? "(abc) " + oAbc:Emit()
? "--------"

//  Output: (json) {"abc":[1,2,3,4]}
? "(json) " + oJson:Emit()
? "--------"
oAbc:destroy()

a:destroy()
oJson:destroy()
