parser <- newJSONParser()
parser$addData( sample_json )
food <- parser$getObject()
print( food )
#This is equivalent to using FromJSON( sample_json )
#However, sample_json can be split into several parts:
### EXAMPLE 2:
part_1 <- '{ "breakfast" : [ "milk", "fruit loops", "juice" ], '
part_2 <- '"lunch" : [ "left over sushi" ]'
# close off the first object, and create a 2nd JSON object, which is simply an
# array
part_3 <- '} [1,2,3,4,5]'
parser <- newJSONParser()
parser$addData( part_1 )
parser$getObject() #returns NULL - since part_1 isn't complete
parser$addData( part_2 )
parser$getObject() #returns NULL - since part_2 still isn't complete
parser$addData( part_3 )
parser$getObject() #returns the first food object
parser$getObject() #returns the second array
