Class CommandWrapper

java.lang.Object

org.topbraid.spin.util.CommandWrapper

Direct Known Subclasses:

QueryWrapper, UpdateWrapper

public abstract class CommandWrapper
extends Object

Wraps a (pre-compiled) Jena Query or UpdateRequest with its source SPIN object and a human-readable string representation. Also needed to work around the issue of Query.equals/hashCode: Otherwise multiple distinct template calls will be merged into one in HashMaps.

Method Detail

getTemplateBinding

public Map<String,org.apache.jena.rdf.model.RDFNode> getTemplateBinding()

getLabel

public String getLabel()

getSPINCommand

public abstract Command getSPINCommand()

getStatement

public org.apache.jena.rdf.model.Statement getStatement()

getSource

public org.apache.jena.rdf.model.Resource getSource()

Gets the SPIN Query or template call that has created this QueryWrapper.

Returns:

the source

getText

public String getText()

isThisDeep

public boolean isThisDeep()

Checks if ?this is used in any nested block. In such cases, ?this cannot be bound via a BGP inside of the query but needs to be bound in an outside loop

Returns:

true if ?this is used deep within the query

isThisUnbound

public boolean isThisUnbound()

setTemplateBinding

public void setTemplateBinding(Map<String,org.apache.jena.rdf.model.RDFNode> value)
