Examples of org.apache.sling.api.resource.ValueMap

org.apache.sling.api.resource.ValueMap
The ValueMap is an easy way to access properties of a resource. With resources you can use {@link Resource#getValueMap()} to obtain thevalue map of a resource. The various getter methods can be used to get the properties of the resource.
In addition a value map returned by a resource supports getting of deep values, like get("content/title") which is equivalent to call getChild("content") on the resource, get the value map of that resource and call get("title") - but without requiring to do all the checks. Only the following methods support deep reads: {@link #get(Object)}, {@link #get(String,Class)}, {@link #get(String,Object)} and{@link #containsKey(Object)}. A ValueMap should be immutable.
