Method Summary

Modifier and Type	Method	Description
TableReference	getTableReference(NavigablePath navigablePath, String tableExpression, boolean allowFkOptimization, boolean resolve)	Returns the table reference for the table expression, or null if not found.
TableReference	resolveTableReference(NavigablePath navigablePath, String tableExpression, boolean allowFkOptimization)	Like ColumnReferenceQualifier.getTableReference(NavigablePath, String, boolean, boolean), but will throw an exception if no table reference can be found, even after resolving possible table reference joins.

UnionTableReference

public UnionTableReference(String unionTableExpression,
                           String[] subclassTableSpaceExpressions,
                           String identificationVariable,

Method Detail

resolveTableReference

public TableReference resolveTableReference(NavigablePath navigablePath,
                                            String tableExpression,
                                            boolean allowFkOptimization)

Description copied from interface: ColumnReferenceQualifier

Like ColumnReferenceQualifier.getTableReference(NavigablePath, String, boolean, boolean), but will throw an exception if no table reference can be found, even after resolving possible table reference joins.

Specified by:

resolveTableReference in interface ColumnReferenceQualifier

Specified by:

resolveTableReference in interface TableReference

Overrides:

resolveTableReference in class NamedTableReference

Parameters:

navigablePath - The path for which to look up the table reference, may be null

tableExpression - The table expression for which to look up the table reference

allowFkOptimization - Whether a foreign key optimization is allowed i.e. use the FK column on the key-side

getTableReference

public TableReference getTableReference(NavigablePath navigablePath,
                                        String tableExpression,
                                        boolean allowFkOptimization,
                                        boolean resolve)

Description copied from interface: ColumnReferenceQualifier

Returns the table reference for the table expression, or null if not found.

Specified by:

getTableReference in interface ColumnReferenceQualifier

Specified by:

getTableReference in interface TableReference

Overrides:

getTableReference in class NamedTableReference

Parameters:

navigablePath - The path for which to look up the table reference, may be null

tableExpression - The table expression for which to look up the table reference

allowFkOptimization - Whether a foreign key optimization is allowed i.e. use the FK column on the key-side

resolve - Whether to potentially create table reference joins for this table group
