getFromClauseAccess

public FromClauseAccessImpl getFromClauseAccess()

Specified by:

getFromClauseAccess in interface SqlAstCreationState

getSqlAstCreationState

public DomainResultCreationStateImpl getSqlAstCreationState()

Description copied from interface: DomainResultCreationState

The underlying state for SQL AST creation

Specified by:

getSqlAstCreationState in interface DomainResultCreationState

Specified by:

getSqlAstCreationState in interface SqlAstProcessingState

getSqlAliasBaseManager

public SqlAliasBaseManager getSqlAliasBaseManager()

Description copied from interface: DomainResultCreationState

Access to the SQL alias helper

Specified by:

getSqlAliasBaseManager in interface DomainResultCreationState

resolveModelPart

public ModelPart resolveModelPart(NavigablePath navigablePath)

Description copied from interface: DomainResultCreationState

Resolve the ModelPart associated with a given NavigablePath. More specific ModelParts should be preferred - e.g. the SingularAssociationAttributeMapping rather than just the EntityTypeMapping for the associated type

Specified by:

resolveModelPart in interface DomainResultCreationState

getSqlExpressionResolver

public DomainResultCreationStateImpl getSqlExpressionResolver()

Specified by:

getSqlExpressionResolver in interface SqlAstCreationState

Specified by:

getSqlExpressionResolver in interface SqlAstProcessingState

registerLockMode

public void registerLockMode(String identificationVariable,
 LockMode explicitLockMode)

Specified by:

registerLockMode in interface SqlAstCreationState

getRegisteredLockModes

public Map<String,LockMode> getRegisteredLockModes()

getCurrentProcessingState

public DomainResultCreationStateImpl getCurrentProcessingState()

Specified by:

getCurrentProcessingState in interface SqlAstCreationState

getCreationContext

public SqlAstCreationContext getCreationContext()

Specified by:

getCreationContext in interface SqlAstCreationState

getSqlAliasBaseGenerator

public SqlAliasBaseGenerator getSqlAliasBaseGenerator()

Specified by:

getSqlAliasBaseGenerator in interface SqlAstCreationState

getLoadQueryInfluencers

public LoadQueryInfluencers getLoadQueryInfluencers()

Specified by:

getLoadQueryInfluencers in interface SqlAstCreationState

applyOnlyLoadByKeyFilters

public boolean applyOnlyLoadByKeyFilters()

Specified by:

applyOnlyLoadByKeyFilters in interface SqlAstCreationState

getParentState

public SqlAstProcessingState getParentState()

Specified by:

getParentState in interface SqlAstProcessingState

resolveSqlExpression

public Expression resolveSqlExpression(SqlExpressionResolver.ColumnReferenceKey key,
 Function<SqlAstProcessingState,Expression> creator)

Description copied from interface: SqlExpressionResolver

Given a qualifier + a qualifiable SqlExpressible, resolve the (Sql)Expression reference.

Specified by:

resolveSqlExpression in interface SqlExpressionResolver

resolveSqlSelection

public SqlSelection resolveSqlSelection(Expression expression,
 JavaType<?> javaType,
 FetchParent fetchParent,
 TypeConfiguration typeConfiguration)

Description copied from interface: SqlExpressionResolver

Resolve the SqlSelection for the given expression

Specified by:

resolveSqlSelection in interface SqlExpressionResolver

visitIdentifierFetch in interface DomainResultCreationState

visitFetches

public ImmutableFetchList visitFetches(FetchParent fetchParent)

Description copied from interface: DomainResultCreationState

Visit fetches for the given parent. We walk fetches via the SqlAstCreationContext because each "context" will define differently what should be fetched (HQL versus load)

Specified by:

visitFetches in interface DomainResultCreationState
