Constructor Detail

AbstractQuerySpace

public AbstractQuerySpace(String uid,
                          QuerySpace.Disposition disposition,
                          ExpandingQuerySpaces querySpaces,
                          boolean canJoinsBeRequired)

Method Detail

sessionFactory

protected SessionFactoryImplementor sessionFactory()

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 QuerySpaces getQuerySpaces()

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

Specified by:

getQuerySpaces in interface QuerySpace

Returns:

The query spaces

getExpandingQuerySpaces

protected ExpandingQuerySpaces getExpandingQuerySpaces()

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 left-hand-side of.

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

Specified by:

getJoins in interface QuerySpace

Returns:

The joins which originate from this query space.

internalGetJoins

protected List<Join> internalGetJoins()
