That is, it should 93 not be consider a "getter", "setter" or "creator". 94<p> 95 In addition, starting with Jackson 1.9, if this is the only annotation 96 associated with a property, it will also cause cause the whole 97 property to be ignored: that is, if setter has this annotation and 98 getter has no annotations, getter is also effectively ignored. 99 It is still possible for different accessors to use different 100 annotations; so if only "getter" is to be ignored, other accessors 101 (setter or field) would need explicit annotation to prevent 102 ignoral (usually <a href="../../../../com/fasterxml/jackson/annotation/JsonProperty.html" title="annotation in com.fasterxml.jackson.annotation"><code>JsonProperty</code></a>). 103 <p> 104 For example, a "getter" method that would otherwise denote 105 a property (like, say, "getValue" to suggest property "value") 106 to serialize, would be ignored and no such property would 107 be output unless another annotation defines alternative method to use. 108<p> 109 Before version 1.9, this annotation worked purely on method-by-method (or field-by-field) 110 basis; annotation on one method or field did not imply ignoring other methods 111 or fields. However, with version 1.9 and above, annotations associated 112 with various accessors (getter, setter, field, constructor parameter) of 113 a logical property are combined; meaning that annotations in one (say, setter) 114 can have effects on all of them (if getter or field has nothing indicating 115 otherwise). 116<p> 117 Annotation is usually used just a like a marker annotation, that 118 is, without explicitly defining 'value' argument (which defaults 119 to <code>true</code>): but argument can be explicitly defined. 120 This can be done to override an existing JsonIgnore by explicitly 121 defining one with 'false' argument. 122<p> 123 Annotation is similar to <a href="http://docs.oracle.com/javase/6/docs/api/javax/xml/bind/annotation/XmlTransient.html?is-external=true" title="class or interface in javax.xml.bind.annotation"><code>XmlTransient</code></a></div> 124</li> 125</ul> 126</div> 127<div class="summary"> 128<ul class="blockList"> 129<li class="blockList"> 130<!-- =========== ANNOTATION TYPE OPTIONAL MEMBER SUMMARY =========== --> 131<ul class="blockList"> 132<li class="blockList"><a name="annotation_type_optional_element_summary"> 133<!-- --> 134</a> 135<h3>Optional Element Summary</h3> 136<table class="overviewSummary" border="0" cellpadding="3" cellspacing="0" summary="Optional Element Summary table, listing optional elements, and an explanation"> 137<caption><span>Optional Elements</span><span class="tabEnd"> </span></caption> 138<tr> 139<th class="colFirst" scope="col">Modifier and Type</th> 140<th class="colLast" scope="col">Optional Element and Description</th> 141</tr> 142<tr class="altColor"> 143<td class="colFirst"><code>boolean</code></td> 144<td class="colLast"><code><strong><a href="../../../../com/fasterxml/jackson/annotation/JsonIgnore.html#value()">value</a></strong></code> 145<div class="block">Optional argument that defines whether this annotation is active 146 or not.</div> 147</td> 148</tr> 149</table> 150</li> 151</ul> 152</li> 153</ul> 154</div> 155<div class="details"> 156<ul class="blockList"> 157<li class="blockList"> 158<!-- ============ ANNOTATION TYPE MEMBER DETAIL =========== --> 159<ul class="blockList"> 160<li class="blockList"><a name="annotation_type_element_detail"> 161<!-- --> 162</a> 163<h3>Element Detail</h3> 164<a name="value()"> 165<!-- --> 166</a> 167<ul class="blockListLast"> 168<li class="blockList"> 169<h4>value</h4> 170<pre>public abstract boolean value</pre> 171<div class="block">Optional argument that defines whether this annotation is active 172 or not.
