protected KeyInfoFactory() 
{

}

Default constructor, for invocation by subclasses.

 public static KeyInfoFactory getInstance() 
{
        return getInstance("DOM");
}

Returns a KeyInfoFactory that supports the default XML processing mechanism and representation type ("DOM").

This method uses the standard JCA provider lookup mechanism to locate and instantiate a KeyInfoFactory implementation of the default mechanism type. It traverses the list of registered security Providers, starting with the most preferred Provider. A new KeyInfoFactory object from the first Provider that supports the DOM mechanism is returned.

Note that the list of registered providers may be retrieved via the Security.getProviders() method.

}

Returns a KeyInfoFactory that supports the specified XML processing mechanism and representation type (ex: "DOM").

This method uses the standard JCA provider lookup mechanism to locate and instantiate a KeyInfoFactory implementation of the desired mechanism type. It traverses the list of registered security Providers, starting with the most preferred Provider. A new KeyInfoFactory object from the first Provider that supports the specified mechanism is returned.

Note that the list of registered providers may be retrieved via the Security.getProviders() method.

        return factory;
}

Returns a KeyInfoFactory that supports the requested XML processing mechanism and representation type (ex: "DOM"), as supplied by the specified provider. Note that the specified Provider object does not have to be registered in the provider list.

}

Returns a KeyInfoFactory that supports the requested XML processing mechanism and representation type (ex: "DOM"), as supplied by the specified provider. The specified provider must be registered in the security provider list.

Note that the list of registered providers may be retrieved via the Security.getProviders() method.

 public final String getMechanismType() 
{
        return mechanismType;
}

Returns the type of the XML processing mechanism and representation supported by this KeyInfoFactory (ex: "DOM")

 public final Provider getProvider() 
{
        return provider;
}

Returns the provider of this KeyInfoFactory.

 abstract public URIDereferencer getURIDereferencer()
Returns a reference to the URIDereferencer that is used by
default to dereference URIs in RetrievalMethod  objects.

 abstract public boolean isFeatureSupported(String feature)
Indicates whether a specified feature is supported.

    String id)
Creates a KeyInfo containing the specified list of key
information types and optional id. The
id parameter represents the value of an XML
ID attribute and is useful for referencing
the KeyInfo from other XML structures.
