Parameters:

Method Detail

getUpdateType

public final UpdateType getUpdateType()

getSourceGraph

public ConstantNode getSourceGraph()

The ConstantNode for the source graph (for operations which have this concept).

Throws:

UnsupportedOperationException - if this concept is not supported by this type of Update operation.

setSourceGraph

public void setSourceGraph(ConstantNode sourceGraph)

getTargetGraph

public ConstantNode getTargetGraph()

The ConstantNode for the target graph (for operations which have this concept). If there is only one graph on which the operation will have an effect, then it is modeled by this annotation.

Throws:

UnsupportedOperationException - if this concept is not supported by this type of Update operation.

setTargetGraph

public void setTargetGraph(ConstantNode targetGraph)

isSilent

public boolean isSilent()

The "SILENT" option (default false) (for operations which have this concept).

Throws:

UnsupportedOperationException - if this concept is not supported by this type of Update operation.

setSilent

public void setSilent(boolean silent)

getRequiredBound

public Set<IVariable<?>> getRequiredBound(StaticAnalysis sa)

Description copied from interface: IVariableBindingRequirements

Return the variables used in the node that *must* be bound prior to evaluating the node. For instance, when evaluation a SPARQL 1.1 service and the endpoint is specified through a variable, then this variable must be bound in order to identify the endpoint to which the query is to be sent. By *must* be bound we mean that, if it is possible to bring the variables in a join group in order such that they are bound when executing the construct (e.g., think of a FILTER), then we *must* consider that. However, when the IVariableBindingRequirements#getRequiredBound() interface cannot be satisified, the query may still be valid and return results (for the SPARQL 1.1 service example mentioned above, it may not, for the FILTER it may). The set of these variables must be disjoint from IVariableBindingRequirements#getRequiredUnound().

Returns:

the set of variables that must be bound prior to evaluation

getDesiredBound

public Set<IVariable<?>> getDesiredBound(StaticAnalysis sa)

Description copied from interface: IVariableBindingRequirements

Get variables that are not required to be bound, but desired in the sense that we want them to be bound when evaluating the construct. In general, the more variables are bound, the better, but this might differ for certain constructs. Should only report variables that are *not* reported through method IVariableBindingRequirements.getRequiredBound(StaticAnalysis).

Returns:

the set of variables that are desires to be bound, but not required

setDatasetClauses

public void setDatasetClauses(List<ASTDatasetClause> uc)

Return the ASTDatasetClause list for operations deferred until evaluation stage.
