Detailed Description

Node for the [NOT] ENFORCED column attribute.

Constructor & Destructor Documentation

◆ PT_constraint_enforcement_attr()

PT_constraint_enforcement_attr::PT_constraint_enforcement_attr ( bool  enforced)
inlineexplicit

Member Function Documentation

◆ has_constraint_enforcement()

bool PT_constraint_enforcement_attr::has_constraint_enforcement ( ) const
inlineoverridevirtual

Check for the [NOT] ENFORCED characteristic.

Returns
true if the [NOT] ENFORCED follows the CHECK(...) clause, false otherwise.

Reimplemented from PT_column_attr_base.

◆ is_constraint_enforced()

bool PT_constraint_enforcement_attr::is_constraint_enforced ( ) const
inlineoverridevirtual

Check if constraint is enforced.

Method must be called only when has_constraint_enforcement() is true (i.e when [NOT] ENFORCED follows the CHECK(...) clause).

Returns
true if constraint is enforced. false otherwise.

Reimplemented from PT_column_attr_base.
