getAliasedLHSColumnNamesback to summary
public static String[] getAliasedLHSColumnNames(AssociationType type, String alias, int property, OuterJoinLoadable lhsPersister, Mapping mapping)

Get the qualified (prefixed by alias) names of the columns of the owning entity which are to be used in the join

Parameters
type:AssociationType

The association type for the association that represents the join

alias:String

The left-hand side table alias

property:int

The index of the property that represents the association/join

lhsPersister:OuterJoinLoadable

The persister for the left-hand side of the association/join

mapping:Mapping

The mapping (typically the SessionFactory).

Returns:String[]

The qualified column names.

public static String[] getAliasedLHSColumnNames(AssociationType associationType, String columnQualifier, int propertyIndex, int begin, OuterJoinLoadable lhsPersister, Mapping mapping)

Get the qualified (prefixed by alias) names of the columns of the owning entity which are to be used in the join

Parameters
associationType:AssociationType

The association type for the association that represents the join

columnQualifier:String

The left-hand side table alias

propertyIndex:int

The index of the property that represents the association/join

begin:int

The index for any nested (composites) attributes

lhsPersister:OuterJoinLoadable

The persister for the left-hand side of the association/join

mapping:Mapping

The mapping (typically the SessionFactory).

Returns:String[]

The qualified column names.

getLHSColumnNamesback to summary
public static String[] getLHSColumnNames(AssociationType type, int property, OuterJoinLoadable lhsPersister, Mapping mapping)

Get the unqualified names of the columns of the owning entity which are to be used in the join.

Parameters
type:AssociationType

property:int

The name of the property that represents the association/join

lhsPersister:OuterJoinLoadable

The persister for the left-hand side of the association/join

mapping:Mapping

The mapping (typically the SessionFactory).

Returns:String[]
