Method Details

getGeneralType

public static org.apache.jena.rdf.model.Resource getGeneralType()

This is the superclass of all datasets assemblers

open

public RDFEngine open(org.apache.jena.assembler.Assembler a,
 org.apache.jena.rdf.model.Resource root,
 org.apache.jena.assembler.Mode mode)

Specified by:

open in interface org.apache.jena.assembler.Assembler

Specified by:

open in class org.apache.jena.assembler.assemblers.AssemblerBase

createNamedEngine

protected RDFEngine createNamedEngine(org.apache.jena.assembler.Assembler a,
 org.apache.jena.rdf.model.Resource root)

Indirection to allow subclasses to have a pool of created datasets (e.g. NamedDatasetAssembler).

Not used by TDB with a location because databases required to be shared system-wide by location. This includes in-memory named locations.

createEngine

protected abstract RDFEngine createEngine(org.apache.jena.assembler.Assembler a,
 org.apache.jena.rdf.model.Resource root)

Create a fresh dataset from the description.

createBaseDataset

protected RDFEngine createBaseDataset(org.apache.jena.rdf.model.Resource dbAssem,
 org.apache.jena.rdf.model.Property pDataset)

Helper for datasets that layer on top of other datasets. The property is usually ja:dataset. Assemble a DatasetGraph from description referred to by resource-property.
