Specified by:

reset in interface BlankNodeAllocator

alloc

public org.apache.jena.graph.Node alloc(String label)

Description copied from interface: BlankNodeAllocator

Allocate based on a non-null label. Calling this twice, with the same label will generate equivalent nodes but they may not be identical (i.e they are .equals but may not be ==)

Specified by:

alloc in interface BlankNodeAllocator

create

public org.apache.jena.graph.Node create()

Description copied from interface: BlankNodeAllocator

Create a fresh blank node, different from anything generated so far. Will not clash with a node allocated by BlankNodeAllocator.alloc(java.lang.String)

Specified by:
