Class

DuAEPropertyExpression

DuAEPropertyExpression(property)

This class describes an expression and the property containing it.
It is used by the cache engine of DuAEF to work on expressions without applying them and improve performance.
This class is very similar to DuAEProperty except it is lighter and faster, to improve the performance of the expression cache.
Constructor

# new DuAEPropertyExpression(property)

Constructs a new DuAEPropertyExpression
Parameters:
Name Type Description
property PropertyBase | DuAEPropertyExpression | DuAEProperty The property. If a DuAEPropertyExpression is provided, the constructor returns it (it does not make a copy).
This makes it easy to avoid type checking, as you can always pass any property or DuAEPropertyExpression to the constructor to be sure to handle a DuAEPropertyExpression, without any impact on performance.
