cq5 - CQ - Check whether the resource object is valid -

i need check whether resource object valid or not below 'resource' object. example if pass url getresource("some path not available in cq") in case need restrict it

resource resource= resourceresolver.getresource(/content/rc/test/jcr:content"); node node = resource.adaptto(node.class); string parentpagepath= node.getproperty("someproperty").getvalue().getstring(); 

is there way do?

if using getresource null check sufficient. if use resolve, have use !resourceutil.isnonexistingresource(resource). on node level can check existence of property hasproperty.
