Load a JsonArray

See more JSON Examples

Demonstrates how to load a JsonArray.

Note: This example requires Chilkat v9.5.0.64 or greater.

Tcl

load ./chilkat.dll

# This example requires Chilkat v9.5.0.64 or greater.

# Loading into a new JSON array is simple and straightforward.
set a [new_CkJsonArray]

CkJsonArray_Load $a "[ 1,2,3,4 ]"

# Output:  [1,2,3,4]
puts [CkJsonArray_emit $a]
puts "--------"

# 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:

set json [new_CkJsonObject]

CkJsonObject_Load $json "{ \"abc\": [ 1,2,3,4 ] }"

# Output:  (json) {"abc":[1,2,3,4]}
puts "(json) [CkJsonObject_emit $json]"
puts "--------"

# abc is a CkJsonArray
set abc [CkJsonObject_ArrayOf $json "abc"]
# When Load is called, abc becomes it's own document, and the original is not modified.
CkJsonArray_Load $abc "[ 5,6,7,8 ]"

# Output: (abc) [5,6,7,8]
puts "(abc) [CkJsonArray_emit $abc]"
puts "--------"

# Output: (json) {"abc":[1,2,3,4]}
puts "(json) [CkJsonObject_emit $json]"
puts "--------"
delete_CkJsonArray $abc


delete_CkJsonArray $a
delete_CkJsonObject $json
