    @ThreadSafety(level=NOT_THREADSAFE)
    public final class RegularExpressionJSONObjectFilter
    extends JSONObjectFilter
    This class provides an implementation of a JSON object filter that can be used to identify JSON objects that have a particular value for a specified field.
    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 a "regular expression" filter are:
    • field -- A field path specifier for the JSON field for which to make the determination. This may be either a single string or an array of strings as described in the "Targeting Fields in JSON Objects" section of the class-level documentation for JSONObjectFilter.
    • regularExpression -- The regular expression to use to identify matching values. It must be compatible for use with the Java java.util.regex.Pattern class.
    The fields that may optionally be included in a "regular expression" filter are:
    • matchAllElements -- Indicates whether all elements of an array must match the provided regular expression. If present, this field must have a Boolean value of true (to indicate that all elements of the array must match the regular expression) or false (to indicate that at least one element of the array must match the regular expression). If this is not specified, then the default behavior will be to require only at least one matching element. This field will be ignored for JSON objects in which the specified field has a value that is not an array.

    Example

    The following is an example of a "regular expression" filter that will match any JSON object with a top-level field named "userID" with a value that starts with an ASCII letter and contains only ASCII letters and numeric digits:
       { "filterType" : "regularExpression",
         "field" : "userID",
         "regularExpression" : "^[a-zA-Z][a-zA-Z0-9]*$" }
     
    The above filter can be created with the code:
       RegularExpressionJSONObjectFilter filter =
              new RegularExpressionJSONObjectFilter("userID",
                   "^[a-zA-Z][a-zA-Z0-9]*$");
