Replace Transformation

Use:	"@jdt.replace" : <Value> (Case sensitive)

Value Type:	Behavior
Primitive	Replaces the current node with the given value
Object	If the object contains JDT attributes, apply them. See Attributes. If not, replaces the node with the given object.
Array	Applies merge with each element of the array as the transformation value. If the transformation value is an array, replace the node with the given array.

Example

Source:

{
    "A" : {
        "A1" : "11"
    },
    "B" : {
        "1B" : 12,
        "2B" : 22
    },
    "C" : {
        "C1" : 31,
        "C2" : 32
    }
}

Transform:

{
    "A": {
        "@jdt.replace": 1
    },
    "B": {
        "@jdt.replace": {
            "B1": 11,
            "B2": 12
        }
    },
    "C": {
        // Double brackets are needed to specify
        // the array as the transformation value
        "@jdt.replace": [[
            {
                "Value": 31
            },
            {
                "Value": 32
            }
        ]]
    }
}

Result:

{
    "A" : 1,
    "B" : {
        "B1" : 11,
        "B2" : 12
    },
    "C" : [
        {
            "Value": 31
        },
        {
            "Value": 32
        }
    ]
}

Path Attribute

The @jdt.path attribute can be used to specify the absolute or relative path to the nodes that should be replaced. It can also be used to specify objects within arrays that should be replaced.

Source:

{
    "A" : {
        "A1" : 11,
        "A2" : "Replace"
    },
    "B" : [
        {
            "ReplaceThis" :true
        },
        {
            "ReplaceThis" : false
        }
    ]
}

Transform:

{
    "@jdt.replace" : {
        "@jdt.path" : "$.A.A2",
        "@jdt.value" : 12
    },
    "B" : {
        "@jdt.replace" : {
            "@jdt.path" : "@[?(@.ReplaceThis == true)]",
            "@jdt.value" : {
                "Replaced" : true
                }
        }
    }
}

Result:

{
    "A" : {
        "A1" : 11,
        "A2" : 12
    },
    "B" : [
        {
            // The entire object was replaced
            "Replaced" : true
        },
        {
            "ReplaceThis" : false
        }
    ]
}
