Method Detail

convertToMap

public static java.util.Map<java.lang.String,java.lang.Object> convertToMap(ToXContent part)
                                                                     throws java.io.IOException

Throws:

java.io.IOException

differenceBetweenMapsIgnoringArrayOrder

public static java.lang.String differenceBetweenMapsIgnoringArrayOrder(java.util.Map<java.lang.String,java.lang.Object> first,
                                                                       java.util.Map<java.lang.String,java.lang.Object> second)

Compares to maps generated from XContentObjects. The order of elements in arrays is ignored.

Returns:

null if maps are equal or path to the element where the difference was found

insertRandomFields

public static BytesReference insertRandomFields(XContentType contentType,
                                                BytesReference xContent,
                                                java.util.function.Predicate<java.lang.String> excludeFilter,
                                                java.util.Random random)
                                         throws java.io.IOException

This method takes the input xContent data and adds a random field value, inner object or array into each json object. This can e.g. be used to test if parsers that handle the resulting xContent can handle the augmented xContent correctly, for example when testing lenient parsing. If the xContent output contains objects that should be skipped of such treatment, an optional filtering Predicate can be supplied that checks xContent paths that should be excluded from this treatment. This predicate should check the xContent path that we want to insert to and return true if the path should be excluded. Paths are string concatenating field names and array indices, so e.g. in:

 {
      "foo1 : {
          "bar" : [
              { ... },
              { ... },
              {
                  "baz" : {
                      // insert here
                  }
              }
          ]
      }
 }
 

"foo1.bar.2.baz" would point to the desired insert location. To exclude inserting into the "foo1" object we would user a Predicate like

 
      (path) -> path.endsWith("foo1")
 
 

or if we don't want any random insertions in the "foo1" tree we could use

 
      (path) -> path.contains("foo1")
 
 

Throws:

java.io.IOException
