Usage
getBlankNodeId(.Object)
# S4 method for class 'Node'
getBlankNodeId(.Object)
Arguments
- .Object
a Node object
Value
a blank node identifier
Details
When a Node object is initialized with no value specified, i.e. node <- Node(""),
a blank node is created and a locally unique identifier is generated by librdf. This method
retrieves this identifier and returns in to the caller.
Examples
world <- new("World")
# a blank node is created with a unique identifier generated by librdf
node <- new("Node", world, blank=NULL)
nodeId <- getBlankNodeId(node)
