Constructor Detail

AbstractQuerySpace

public AbstractQuerySpace(String uid,
                  QuerySpace.Disposition disposition,
                  QuerySpacesImpl querySpaces,
                  boolean canJoinsBeRequired,
                  SessionFactoryImplementor sessionFactory)

Method Detail

sessionFactory

protected SessionFactoryImplementor sessionFactory()

Overrides:

sessionFactory in class AbstractPlanNode

canJoinsBeRequired

public boolean canJoinsBeRequired()

Can any joins created from here (with this as the left-hand side) be required joins?

Returns:

true indicates joins can be required; false indicates they cannot.

getQuerySpaces

public QuerySpacesImpl getQuerySpaces()

Provides subclasses access to the spaces to which this space belongs.

Specified by:

getQuerySpaces in interface QuerySpace

Returns:

The query spaces

getUid

public String getUid()

Description copied from interface: QuerySpace

The uid/alias which uniquely identifies this QuerySpace. Can be used to uniquely reference this QuerySpace elsewhere.

Specified by:

getUid in interface QuerySpace

Returns:

The uid

See Also:

QuerySpaces.findQuerySpaceByUid(java.lang.String)

getDisposition

public QuerySpace.Disposition getDisposition()

Description copied from interface: QuerySpace

What type of QuerySpace (more-specific) is this?

Specified by:

getDisposition in interface QuerySpace

Returns:

The enum value representing the more-specific type of QuerySpace

getJoins

public Iterable<Join> getJoins()

Description copied from interface: QuerySpace

Obtain all joins which originate from this QuerySpace, in other words, all the joins which this QuerySpace is the right-hand-side of.

For all the joins returned here, Join.getRightHandSide() should point back to this QuerySpace such that space.getJoins().forEach{ join -> join.getRightHandSide() == space } is true for all.

Specified by:

getJoins in interface QuerySpace

Returns:

The joins which originate from this query space.
