Field Detail

SALT

private static java.util.UUID SALT

Used by #bnodePrefix() to get a unique UUID per JVM run

bnodePrefix

final java.lang.String bnodePrefix

Prefix to use in blank node identifiers

factory

final JsonLdRDF factory

rdfDataSet

com.github.jsonldjava.core.RDFDataset rdfDataSet

The underlying JSON-LD RDFDataset.

Note: This is NOT final as it is reset to null by close() (to free memory).
