Class RetrievalFilter

    • Method Detail

      • hasAndAll

        public final boolean hasAndAll()
        For responses, this returns true if the service returned a value for the AndAll property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • andAll

        public final List<RetrievalFilter> andAll()

        Knowledge base data sources are returned if their metadata attributes fulfill all the filter conditions inside this list.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAndAll() method.

        Returns:
        Knowledge base data sources are returned if their metadata attributes fulfill all the filter conditions inside this list.
      • equalsValue

        public final FilterAttribute equalsValue()

        Knowledge base data sources are returned if they contain a metadata attribute whose name matches the key and whose value matches the value in this object.

        The following example would return data sources with an animal attribute whose value is cat:

        "equals": { "key": "animal", "value": "cat" }

        Returns:
        Knowledge base data sources are returned if they contain a metadata attribute whose name matches the key and whose value matches the value in this object.

        The following example would return data sources with an animal attribute whose value is cat:
