Constructor Detail

DatasetNode

public DatasetNode(DatasetNode op)

Constructor required for com.bigdata.bop.BOpUtility#deepCopy(FilterNode).

DatasetNode

public DatasetNode(BOp[] args,
           Map<String,Object> anns)

Required shallow copy constructor.

DatasetNode

public DatasetNode(Set<IV> defaultGraphs,
           Set<IV> namedGraphs,
           boolean update)

Parameters:

defaultGraphs -

namedGraphs -

update - true iff this is a SPARQL update.

DatasetNode

public DatasetNode(Set<IV> defaultGraphs,
           Set<IV> namedGraphs,
           IElementFilter<ISPO> defaultGraphFilter,
           IElementFilter<ISPO> namedGraphFilter,
           boolean update)

DatasetNode

public DatasetNode(DataSetSummary defaultGraphs,
           DataSetSummary namedGraphs)

DatasetNode

public DatasetNode(org.openrdf.query.Dataset dataset,
           boolean update)

DatasetNode

public DatasetNode(DataSetSummary defaultGraphs,
           DataSetSummary namedGraphs,
           IElementFilter<ISPO> defaultGraphFilter,
           IElementFilter<ISPO> namedGraphFilter)

Core constructor implementation.

Parameters:

defaultGraphs - The list of default graphs (optional). When not specified, all graphs will be used unless a defaultGraphsFilter is applied.

namedGraphs - The list of named graphs (optional). When not specified, all graphs will be used unless a namedGraphsFilter is applied.

defaultGraphFilter - A filter for default graphs (optional and typically only used when the defaultGraphs is null, e.g., to apply ACLs).

namedGraphFilter - A filter for named graphs (optional and typically only used when the namedGraphs is null, e.g., to apply ACLs).

toString

public String toString(int indent)

Description copied from class: CoreBaseBOp

The contract of this method at this level is under-specified. Sub-classes may choose between: - return a string representation of the object, similar to the use of CoreBaseBOp.toString() Or: - return a pretty-print representation of the object with indent Note that the former contract may or may not include recursive descent through a tree-like object, whereas the latter almost certainly does.

Specified by:

toString in interface BOp
