Class SecuredAssembler

java.lang.Object
org.apache.jena.assembler.assemblers.AssemblerBase
org.apache.jena.assembler.assemblers.ModelAssembler
org.apache.jena.permissions.SecuredAssembler
All Implemented Interfaces:
org.apache.jena.assembler.Assembler, AssemblerConstants
public class SecuredAssembler extends org.apache.jena.assembler.assemblers.ModelAssembler implements AssemblerConstants
Assembler for a secured model.

The assembler file should include the following 

 <> ja:loadClass    "org.apache.jena.permission.SecuredAssembler" .

 sec:Model rdfs:subClassOf ja:NamedModel .

 sec:evaluator rdfs:domain sec:Model ;
               rdfs:range sec:Evaluator .
The model definition should include something like. 
 my:secModel a sec:Model ;
    sec:baseModel my:baseModel ;
    ja:modelName "http://example.com/securedModel" ;
    sec:evaluatorFactory "org.apache.jena.permission.MockSecurityEvaluator" ;
    .
Terms used in above example:
my:secModel
The secured model as referenced in the assembler file.
sec:Model
Identifes my:secModel as a secured model
sec:baseModel
Identifies my:baseModel as the base model we are applying permissions to
my:baseModel
a ja:Model (or subclass) defined elsewhere in the assembler file
ja:modelName
The name of the graph as it will be addressed in the permission environment (see ja:NamedModel examples from Jena)
sec:evaluatorFactory
Identifies "org.apache.jena.permission.MockSecurityEvaluator" as the java class that implements an Evaluator Factory. The Factory must have static method getInstance() that returns a SecurityEvaluator.
or if using an evaluator assembler 
 my:secModel a sec:Model ;
    sec:baseModel my:baseModel ;
    ja:modelName "http://example.com/securedModel" ;
    sec:evaluatorImpl ex:myEvaluator;
    .

 ex:myEvaluator a sec:Evaluator ;
    ex:arg1 "argument 1 for my evaluator constructor" ;
    ex:arg2 "argument 2 for my evaluator constructor" ;
    .
Terms used in above example:
my:secModel
The secured model as referenced in the assembler file.
sec:Model
Identifies my:secModel as a secured model
sec:baseModel
Identifies my:baseModel as the base model we are applying permissions to
my:baseModel
a ja:Model (or subclass) defined elsewhere in the assembler file
ja:modelName
The name of the graph as it will be addressed in the permission environment (see ja:NamedModel examples from Jena)
sec:evaluatorImpl
Identifies ex:myEvaluator as a SecurityEvaluator defined elsewhere in the assembler file. It must subclass as a sec:Evaluator.
ex:arg1 and ex:arg2
Arguments as defined by the user defined security evaluator assembler.
