registerChangedSubject

void registerChangedSubject(Entity subj)

When some Entity was changed (its attribute/value/metadata was added/removed/changed) it should be registered using this method to be validated before saving the context by .

Parameters:

subj -

unregisterChangedSubject

void unregisterChangedSubject(Entity subj)

When some Entity was removed it should be also removed from changed subjects list to prevent validation of non-existent subject

Parameters:

subj -

setValidationMode

Parameters:

performValidation - if true then all changed subjects should be validated before saving of the context. Default value is true. In case of JDBC Context, if RDBMS does not support transactions, validation will not be performed
