public AssemblerUtils()

Method Detail

readPrefixMapping

public static PrefixMapping readPrefixMapping(String file)

init

public static void init()

registerDataset

public static void registerDataset(Resource r,
                                   Assembler a)

Register an assembler that creates a dataset

registerModel

public static void registerModel(Resource r,
                                 Assembler a)

Register an assembler that creates a dataset

register

public static void register(AssemblerGroup g,
                            Resource r,
                            Assembler a,
                            Resource superType)

Register an addition assembler

registerAssembler

public static void registerAssembler(AssemblerGroup group,
                                     Resource r,
                                     Assembler a)

register

readAssemblerFile

public static Model readAssemblerFile(String assemblerFile)

addRegistered

public static Model addRegistered(Model model)

Add any extra information to the model. Such information includes registration of datasets (e.g. TDB1, TDB2) done by register(org.apache.jena.assembler.assemblers.AssemblerGroup, org.apache.jena.rdf.model.Resource, org.apache.jena.assembler.Assembler, org.apache.jena.rdf.model.Resource) (registerDataset(org.apache.jena.rdf.model.Resource, org.apache.jena.assembler.Assembler), registerModel(org.apache.jena.rdf.model.Resource, org.apache.jena.assembler.Assembler). It avoids directly modifying Assembler.general.

Parameters:

model -

Returns:

Model The same model after modification.

build

public static Object build(String assemblerFile,
                           String typeURI)

build

public static Object build(String assemblerFile,
                           Resource type)

parseContext

public static Context parseContext(Resource r)

Look for and build context declarations. e.g.

 root ... ;
   ja:context [ ja:cxtName "arq:queryTimeout" ;  ja:cxtValue "10000" ] ;
   ...
 

Short name forms of context parameters can be used. Setting as string "undef" will remove the context setting. Returns null when there is no JA.context on the resource.

setContext

public static void setContext(Resource r,
                              Context context)

Deprecated. Use mergeContext(Resource, Context)

mergeContext

public static void mergeContext(Resource r,
                                Context context)

Look for and merge in context declarations. e.g.

 root ... ;
   ja:context [ ja:cxtName "arq:queryTimeout" ;  ja:cxtValue "10000" ] ;
   ...
 

Short name forms of context parameters can be used. Setting as string "undef" will remove the context setting.
