The AWS States Language specification describes the role of the InputPath and Parameters fields but does not give an example of the filters being used together.
My understanding is that, if specified, the JSON path given by the InputPath field is applied to the raw input producing the effective input. Then, if specified, the value of the parameters field is applied, modifying the effective input.
Extending the example given in the spec, given the following Task state definition:
"X":
"Type": "Task",
"Resource": "arn:aws:swf:us-east-1:123456789012:task:X",
"Next": "Y",
"InputPath": "$.sub",
"Parameters":
"flagged": true,
"parts":
"first.$": "$.vals[0]",
"last3.$": "$.vals[3:]"
then, given the following input:
"flagged": 7,
"sub" :
"vals": [0, 10, 20, 30, 40, 50]
the effective input to the code identified in the Resource field would be:
"flagged": true,
"parts":
"first": 0,
"last3": [30, 40, 50]
Is my interpretation correct?
