Class ORJSONObjectFilter

  • All Implemented Interfaces:
    java.io.Serializable

    @Mutable
    @ThreadSafety(level=NOT_THREADSAFE)
    public final class ORJSONObjectFilter
    extends JSONObjectFilter
    This class provides an implementation of a JSON object filter that can perform a logical OR across the result obtained from a number of filters. The OR filter will match an object only if at least one (and optionally, exactly one) of the filters contained in it matches that object. An OR filter with an empty set of embedded filters will never match any object.
    NOTE: This class, and other classes within the com.unboundid.ldap.sdk.unboundidds package structure, are only supported for use against Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 server products. These classes provide support for proprietary functionality or for external specifications that are not considered stable or mature enough to be guaranteed to work in an interoperable way with other types of LDAP servers.

    The fields that are required to be included in an "OR" filter are:
    • orFilters -- An array of JSON objects, each of which is a valid JSON object filter. At least one of these filters must match a JSON object in order for the OR filter to match. If this is an empty array, then the filter will not match any object.
    The fields that may optionally be included in an "OR" filter are:
    • exclusive -- Indicates whether this should be treated as an exclusive OR. If this is present, then it must have a Boolean value of either true (to indicate that this OR filter will only match a JSON object if exactly one of the embedded filters matches that object), or false (to indicate that it is a non-exclusive OR and will match a JSON object as long as at least one of the filters matches that object). If this is not specified, then a non-exclusive OR will be performed.

    Examples

    The following is an example of an OR filter that will never match any JSON object:
       { "filterType" : "or",
         "orFilters" : [ ] }
     
    The above filter can be created with the code:
       ORJSONObjectFilter filter = new ORJSONObjectFilter();
     


    The following is an example of an OR filter that will match any JSON object that contains either a top-level field named "homePhone" or a top-level field named "workPhone":
       { "filterType" : "or",
         "orFilters" : [
           { "filterType" : "containsField",
              "field" : "homePhone" },
           { "filterType" : "containsField",
              "field" : "workPhone" } ] }
     
    The above filter can be created with the code:
       ORJSONObjectFilter filter = new ORJSONObjectFilter(
            new ContainsFieldJSONObjectFilter("homePhone"),
            new EqualsJSONObjectFilter("workPhone"));

        Creates a new instance of this filter type with the provided information.
        Parameters:
        orFilters - The set of filters for this OR filter. At least one of these filters must match a JSON object in order for this OR filter to match that object. If this is null or empty, then this OR filter will never match any JSON object.

        Parameters:
        orFilters - The set of filters for this OR filter. At least one of these filters must match a JSON object in order for this OR filter to match that object. If this is null or empty, then this OR filter will never match any JSON object.
