Constructor Details

ListProperty

protected ListProperty(String name,
 Expression expression,
 Class<V> entityType)

Constructs a new property with the given name and expression

Parameters:

name - of the property (will be used as alias for the expression)

expression - expression for property

entityType - type of related entity

Method Details

alias

public ListProperty<V> alias(String alias)

Creates alias with different name for this property

Overrides:

alias in class BaseProperty<List<V extends Persistent>>

outer

public ListProperty<V> outer()

Returns a version of this property that represents an OUTER join. It is up to caller to ensure that the property corresponds to a relationship, as "outer" attributes make no sense.

enclosing

public ListProperty<V> enclosing()

Overrides:

enclosing in class BaseProperty<List<V extends Persistent>>

Returns:

property that will be translated relative to parent query
