Method Summary

Modifier and Type	Method	Description
SqmAliasedNode<?>	findAliasedNodeByAlias(String alias)	Find a node (if one) by the explicit alias assigned to it within the select-clause
SqmAliasedNode<?>	findAliasedNodeByPosition(int position)	Find an SqmSelection by its position in the SqmSelectClause
Integer	findAliasedNodePosition(String alias)	Find the position of a node with the given alias, relative to the underlying SQL select-list.
<X extends SqmFrom<?,?>> X	findFromByAlias(String alias, boolean searchParent)	Find a SqmFrom by its identification variable (alias).
<X extends SqmFrom<?,?>> X	findFromByPath(NavigablePath navigablePath)	Find a SqmFrom by its NavigablePath.

void	register(SqmPath<?> sqmPath)	Register an SqmPath
void	register(SqmAliasedNode<?> node)	Register a node aliased within the select-clause
void	registerByAliasOnly(SqmFrom<?,?> sqmFrom)	Register an SqmFrom by alias only.
<E> void	replace(SqmEntityJoin<E> sqmJoin, SqmRoot<E> sqmRoot)	Used with JPA compliance to treat secondary query roots as cross-joins.
<X extends SqmFrom<?,?>> X	resolveFrom(SqmPath<?> path)	Similar to SqmPathRegistry.resolveFrom(org.hibernate.spi.NavigablePath, java.util.function.Function<org.hibernate.spi.NavigablePath, org.hibernate.query.sqm.tree.from.SqmFrom<?, ?>>), but accepting a SqmPath to be used to create and register a SqmFrom if none yet registered.
<X extends SqmFrom<?,?>> X	resolveFrom(NavigablePath navigablePath, Function<NavigablePath,SqmFrom<?,?>> creator)	Similar to SqmPathRegistry.findFromByPath(org.hibernate.spi.NavigablePath), but accepting a producer to be used to create and register a SqmFrom if none yet registered.

Constructor Detail

SqmPathRegistryImpl

public SqmPathRegistryImpl(SqmCreationProcessingState associatedProcessingState)

Method Detail

register

public void register(SqmPath<?> sqmPath)

Description copied from interface: SqmPathRegistry

Register an SqmPath

Specified by:

register in interface SqmPathRegistry

registerByAliasOnly

public void registerByAliasOnly(SqmFrom<?,?> sqmFrom)

Description copied from interface: SqmPathRegistry

Register an SqmFrom by alias only. Effectively, this makes the from node only resolvable via the alias, which means that the from node is ignored in SqmPathRegistry.findFromExposing(String).

Specified by:

registerByAliasOnly in interface SqmPathRegistry

replace

public <E> void replace(SqmEntityJoin<E> sqmJoin,
                        SqmRoot<E> sqmRoot)

Description copied from interface: SqmPathRegistry

Used with JPA compliance to treat secondary query roots as cross-joins. Here we will replace the sqmRoot with the sqmJoin

Specified by:

replace in interface SqmPathRegistry

findFromByPath

public <X extends SqmFrom<?,?>> X findFromByPath(NavigablePath navigablePath)

Description copied from interface: SqmPathRegistry

Find a SqmFrom by its NavigablePath. Will search any parent contexts as well

Specified by:

findFromByPath in interface SqmPathRegistry

Returns:

matching SqmFrom or null

findFromByAlias

public <X extends SqmFrom<?,?>> X findFromByAlias(String alias,
                                                        boolean searchParent)

Description copied from interface: SqmPathRegistry

Find a SqmFrom by its identification variable (alias). If the SqmFrom is found in a parent context, the correlation for the path will be returned.

Specified by:

findFromByAlias in interface SqmPathRegistry

Returns:

matching SqmFrom or null

findFromExposing

public <X extends SqmFrom<?,?>> X findFromExposing(String navigableName)

Description copied from interface: SqmPathRegistry

Find a SqmFrom which exposes a Navigable by the given name. Will search any parent contexts as well

Specified by:

findFromExposing in interface SqmPathRegistry

Returns:

matching SqmFrom or null

resolveFrom

public <X extends SqmFrom<?,?>> X resolveFrom(NavigablePath navigablePath,
                                                    Function<NavigablePath,SqmFrom<?,?>> creator)

Description copied from interface: SqmPathRegistry

Similar to SqmPathRegistry.findFromByPath(org.hibernate.spi.NavigablePath), but accepting a producer to be used to create and register a SqmFrom if none yet registered.

Specified by:

resolveFrom in interface SqmPathRegistry

Returns:

The existing or just-created SqmFrom

resolveFrom

public <X extends SqmFrom<?,?>> X resolveFrom(SqmPath<?> path)

Description copied from interface: SqmPathRegistry

Similar to SqmPathRegistry.resolveFrom(org.hibernate.spi.NavigablePath, java.util.function.Function<org.hibernate.spi.NavigablePath, org.hibernate.query.sqm.tree.from.SqmFrom<?, ?>>), but accepting a SqmPath to be used to create and register a SqmFrom if none yet registered.

Specified by:

resolveFrom in interface SqmPathRegistry

Returns:

The existing or just-created SqmFrom

findAliasedNodeByAlias

public SqmAliasedNode<?> findAliasedNodeByAlias(String alias)

Description copied from interface: SqmPathRegistry

Find a node (if one) by the explicit alias assigned to it within the select-clause

Specified by:

findAliasedNodeByAlias in interface SqmPathRegistry

Returns:

The matching node, or null

findAliasedNodePosition

public Integer findAliasedNodePosition(String alias)

Description copied from interface: SqmPathRegistry

Find the position of a node with the given alias, relative to the underlying SQL select-list.

Specified by:

findAliasedNodePosition in interface SqmPathRegistry

Returns:

The position, or null

findAliasedNodeByPosition

public SqmAliasedNode<?> findAliasedNodeByPosition(int position)

Description copied from interface: SqmPathRegistry

Find an SqmSelection by its position in the SqmSelectClause

Specified by:

findAliasedNodeByPosition in interface SqmPathRegistry

Returns:

The matching node, or null

register

public void register(SqmAliasedNode<?> node)

Description copied from interface: SqmPathRegistry

Register a node aliased within the select-clause

Specified by:

register in interface SqmPathRegistry
