Classpublic class CrossDomainRSLItem

Cross-domain RSL Item Class. The rsls are typically located on a different host than the loader. There are signed and unsigned Rsls, both have a digest to confirm the correct rsl is loaded. Signed Rsls are loaded by setting the digest of the URLRequest. Unsigned Rsls are check using actionScript to calculate a sha-256 hash of the loaded bytes and compare them to the expected digest.

Constructor Detail
CrossDomainRSLItem()Constructor
public function CrossDomainRSLItem(rslUrls:Array, policyFileUrls:Array, digests:Array, hashTypes:Array, isSigned:Array)

Create a cross-domain RSL item to load.

Parameters
rslUrls:Array — Array of Strings, may not be null. Each String is the url of an RSL to load.
 
policyFileUrls:Array — Array of Strings, may not be null. Each String contains the url of an policy file which may be required to allow the RSL to be read from another domain. An empty string means there is no policy file specified.
 
digests:Array — Array of Strings, may not be null. A String contains the value of the digest computed by the hash in the corresponding entry in the hashTypes Array. An empty string may be provided for unsigned RSLs to loaded them without verifying the digest. This is provided as a development cycle convenience and should not be used in a production application.
 
hashTypes:Array — Array of Strings, may not be null. Each String identifies the type of hash used to compute the digest. Currently the only valid value is SHA256.TYPE_ID.
 
isSigned:Array — Array of boolean, may not be null. Each boolean value specifies if the RSL to be loaded is a signed or unsigned RSL. If the value is true the RSL is signed. If the value is false the RSL is unsigned.
Method Detail
hasFailover()method
public function hasFailover():Boolean
