065/**
066 * This class provides an implementation of a JSON object filter that can be
067 * used to identify JSON objects that have at least one value for a specified
068 * field that is greater than a given value.
069 * <BR>
070 * <BLOCKQUOTE>
071 *   <B>NOTE:</B>  This class, and other classes within the
072 *   {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only
073 *   supported for use against Ping Identity, UnboundID, and
074 *   Nokia/Alcatel-Lucent 8661 server products.  These classes provide support
075 *   for proprietary functionality or for external specifications that are not
076 *   considered stable or mature enough to be guaranteed to work in an
077 *   interoperable way with other types of LDAP servers.
078 * </BLOCKQUOTE>
079 * <BR>
080 * The fields that are required to be included in a "greater than" filter are:
081 * <UL>
082 *   <LI>
083 *     {@code field} -- A field path specifier for the JSON field for which to
084 *     make the determination.  This may be either a single string or an array
085 *     of strings as described in the "Targeting Fields in JSON Objects" section
086 *     of the class-level documentation for {@link JSONObjectFilter}.
087 *   </LI>
088 *   <LI>
089 *     {@code value} -- The value to use in the matching.  It must be either a
090 *     string (which will be compared against other strings using lexicographic
091 *     comparison) or a number.
092 *   </LI>
093 * </UL>
094 * The fields that may optionally be included in a "greater than" filter are:
095 * <UL>
096 *   <LI>
097 *     {@code allowEquals} -- Indicates whether to match JSON objects that have
098 *     a value for the specified field that matches the provided value.  If
099 *     present, this field must have a Boolean value of either {@code true} (to
100 *     indicate that it should be a "greater-than or equal to" filter) or
101 *     {@code false} (to indicate that it should be a strict "greater-than"
102 *     filter).  If this is not specified, then the default behavior will be to
103 *     perform a strict "greater-than" evaluation.
104 *   </LI>
105 *   <LI>
106 *     {@code matchAllElements} -- Indicates whether all elements of an array
107 *     must be greater than (or possibly equal to) the specified value.  If
108 *     present, this field must have a Boolean value of {@code true} (to
109 *     indicate that all elements of the array must match the criteria for this
110 *     filter) or {@code false} (to indicate that at least one element of the
111 *     array must match the criteria for this filter).  If this is not
112 *     specified, then the default behavior will be to require only at least
113 *     one matching element.  This field will be ignored for JSON objects in
114 *     which the specified field has a value that is not an array.
115 *   </LI>
116 *   <LI>
117 *     {@code caseSensitive} -- Indicates whether string values should be
118 *     treated in a case-sensitive manner.  If present, this field must have a
119 *     Boolean value of either {@code true} or {@code false}.  If it is not
120 *     provided, then a default value of {@code false} will be assumed so that
121 *     strings are treated in a case-insensitive manner.
122 *   </LI>
123 * </UL>
124 * <H2>Example</H2>
125 * The following is an example of a "greater than" filter that will match any
126 * JSON object with a top-level field named "salary" with a value that is
127 * greater than or equal to 50000:
128 * <PRE>
129 *   { "filterType" : "greaterThan",
130 *     "field" : "salary",
131 *     "value" : 50000,
132 *     "allowEquals" : true }
133 * </PRE>
134 * The above filter can be created with the code:
135 * <PRE>
136 *   GreaterThanJSONObjectFilter filter =
137 *        new GreaterThanJSONObjectFilter("salary", 50000);
138 *   filter.setAllowEquals(true);
139 * </PRE>
