Constructor & Destructor Documentation

te::da::CheckConstraint::CheckConstraint	(	DataSetType *	dt = `0`,
		unsigned int	id = `0`
	)

Constructor.

Parameters

dt	The DataSetType associated to the check constraint.
id	The constraint identifier.

Note: The new constraint will belong to the given DataSetType.

Warning: The identifier value (id) may be used by data source implementations. So, don't rely on its value!

te::da::CheckConstraint::CheckConstraint	(	const std::string &	name,
		DataSetType *	dt = `0`,
		unsigned int	id = `0`
	)

Constructor.

Parameters

name	The check constraint name.
parent	The parent DataSetType of this check constraint.
id	The constraint identifier.

Note: The new constraint will belong to the given DataSetType.

Warning: The identifier value (id) may be used by data source implementations. So, don't rely on its value!

te::da::CheckConstraint::CheckConstraint ( const CheckConstraint & rhs )

Copy constructor not allowed.

The new object will not have an associated DataSetType.

Parameters

rhs	Right-hand-side instance.

te::da::CheckConstraint::~CheckConstraint ( )

inline

Destructor.

Definition at line 87 of file CheckConstraint.h.

Member Function Documentation

Constraint* te::da::CheckConstraint::clone ( )

virtual

It returns a clone of the object.

The new object will not have an associated DataSetType.

Returns: A clone of the object.

Implements te::da::Constraint.

virtual DataSetType* te::da::Constraint::getDataSetType ( ) const

inlinevirtualinherited

It returns the DataSetType associated to the constraint.

Returns: The DataSetType associated to the constraint.

Definition at line 133 of file Constraint.h.

const std::string& te::da::CheckConstraint::getExpression ( ) const

inline

It returns the check constraint expression.

Returns: The check constraint expression.

Definition at line 105 of file CheckConstraint.h.

virtual unsigned int te::da::Constraint::getId ( ) const

inlinevirtualinherited

It returns the constraint identifier.

Returns: A number that identifies the constraint.

Warning: The identifier value (id) may be used by data source implementations. So, don't rely on its value!

Definition at line 103 of file Constraint.h.

virtual const std::string& te::da::Constraint::getName ( ) const

inlinevirtualinherited

It returns the constraint name.

Returns: The constraint name.

Definition at line 119 of file Constraint.h.

ConstraintType te::da::CheckConstraint::getType ( ) const

inlinevirtual

It returns the constraint type: CHECK.

Returns: The constraint type CHECK.

Implements te::da::Constraint.

Definition at line 119 of file CheckConstraint.h.

References te::da::CHECK.

CheckConstraint& te::da::CheckConstraint::operator= ( const CheckConstraint & rhs )

Assignment operator.

The new object will not have an assigned DataSetType.

Parameters

rhs	Right-hand-side instance.

Returns: A reference to this.

virtual void te::da::Constraint::setDataSetType ( DataSetType * dt )

inlinevirtualinherited

It sets the DataSetType associated to the constraint.

Parameters

dt	The DataSetType associated to this constraint.

Warning: Take care when calling this method. If the constraint belongs to a DataSetType, remember to detach it from the DataSetType before calling this method.

Definition at line 143 of file Constraint.h.

void te::da::CheckConstraint::setExpression ( const std::string & e )

inline

It sets the check constraint expression.

Parameters

name	The check constraint expression.

Definition at line 112 of file CheckConstraint.h.

virtual void te::da::Constraint::setId ( unsigned int id )

inlinevirtualinherited

It sets the constraint identifier.

Parameters

id	A number that identifies the constraint.

Warning: The identifier value (id) may be used by data source implementations. So, don't rely on its value!

Definition at line 112 of file Constraint.h.

virtual void te::da::Constraint::setName ( const std::string & name )

inlinevirtualinherited

It sets the constraint name.

Parameters

name	The constraint name.

Definition at line 126 of file Constraint.h.
