setExpression

public static void setExpression(org.eclipse.persistence.indirection.ValueHolderInterface pWorkTextValueHolder,
                                 oracle.odi.domain.texts.WorkTextOrig pExpectedWorkTextOrig,
                                 Expression pExpression)
                          throws java.lang.IllegalArgumentException

Convenient function that set the given expression to the given value holder's WorkText. That method should be used to implement an Expression setter method within domain objects.

This method allow to recycle WorkText instance held by the given ValueHolder. That method simply update the underlying WorkText with the expression property values. If the expression is null and the value holder contains a not null WorkText, then that WorkText is set to null and will be deleted as well as its part and cross refs. However, if the underlying WorkText is null, a new one is created, if required (i.e. the expression isn't null).

Parameters:

pWorkTextValueHolder - the toplink value holder holding the WorkText instance

pExpectedWorkTextOrig - the expected WorkTextOrig

pExpression - the expression to set, can be null

Throws:

DomainRuntimeException - if mismatch between WorkTextOrigs

java.lang.IllegalArgumentException

getExpression

public static Expression getExpression(org.eclipse.persistence.indirection.ValueHolderInterface pWorkTextValueHolder)

Convenient function that get an Expression from the given toplink value holder. That method should be used to implement Expression getter method within domain objects.

If the WorkText instance of the given holder is null, that method will return null. Otherwise, ask the expression from the WorkText instance.

Parameters:

pWorkTextValueHolder - the toplink value holder holding the WorkText instance

Returns:

an Expression from the given WorkText holder
