it.unibz.inf.ontop.iq.node

Interface NativeNode

All Superinterfaces:

Cloneable, ExplicitVariableProjectionNode, IQTree, LeafIQTree, QueryNode

All Known Implementing Classes:

NativeNodeImpl

public interface NativeNode
extends LeafIQTree

Represents a serialized query that can be executed by the DB engine See IntermediateQueryFactory.createNativeNode(it.unibz.inf.ontop.com.google.common.collect.ImmutableSortedSet<it.unibz.inf.ontop.model.term.Variable>, it.unibz.inf.ontop.com.google.common.collect.ImmutableMap<it.unibz.inf.ontop.model.term.Variable, it.unibz.inf.ontop.model.type.DBTermType>, it.unibz.inf.ontop.com.google.common.collect.ImmutableMap<it.unibz.inf.ontop.model.term.Variable, it.unibz.inf.ontop.dbschema.QuotedID>, java.lang.String, it.unibz.inf.ontop.iq.node.VariableNullability) for creating a new instance.

Method Detail

getTypeMap

it.unibz.inf.ontop.com.google.common.collect.ImmutableMap<Variable,DBTermType> getTypeMap()

Every variable is guaranteed to have a type

getVariables

it.unibz.inf.ontop.com.google.common.collect.ImmutableSortedSet<Variable> getVariables()

This set is sorted, useful for instance for using JDBC result sets

Specified by:

getVariables in interface ExplicitVariableProjectionNode

Specified by:

getVariables in interface IQTree

getColumnNames

it.unibz.inf.ontop.com.google.common.collect.ImmutableMap<Variable,QuotedID> getColumnNames()

Needed because certain DBs like Oracle impose constraints on the length of a column name, so the column name may differ from the variable name.

getNativeQueryString

String getNativeQueryString()
