Class JsonArrayFixingInputStream

java.lang.Object

java.io.InputStream

org.owasp.dependencycheck.utils.JsonArrayFixingInputStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class JsonArrayFixingInputStream
extends java.io.InputStream

Fixes a poorly formatted jSON array such as those returned by go list -json -m all.

Example:

{ "name1": "value" } { "name2" : "value" } Would be transformed into: [{ "name1": "value" }, { "name2" : "value" }]

Note that this is a naive implementation and will incorrectly transform a stream if there are '}' contained within the names of values.
