Constructor & Destructor Documentation

◆ UniqueKey() [1/3]

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

Constructor.

Parameters

dt	The DataSetType associated to this uk.
id	The uk identifier.

Postcondition: If dt is provided, the uk 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!

◆ UniqueKey() [2/3]

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

Constructor.

Parameters

name	The unique key (uk) constraint name.
dt	The DataSetType associated to this uk.
id	The uk identifier.

Postcondition: If dt is provided, the uk 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!

◆ UniqueKey() [3/3]

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

Copy constructor.

The new object will not have an associated DataSetType.

Parameters

rhs	Right-hand-side instance.

◆ ~UniqueKey()

te::da::UniqueKey::~UniqueKey ( )

Destructor.

Member Function Documentation

◆ add()

void te::da::UniqueKey::add ( const te::dt::Property * p )

References te::dt::Property::clone().

◆ clone()

Constraint* te::da::UniqueKey::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.

Returns: The DataSetType associated to the constraint.

Definition at line 133 of file Constraint.h.

◆ getId()

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.

◆ getName()

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

inlinevirtualinherited

inlinevirtual

It returns the constraint type: UNIQUEKEY.

Returns: The constraint type UNIQUEKEY.

Implements te::da::Constraint.

Definition at line 153 of file UniqueKey.h.

References te::da::UNIQUE_KEY.

◆ has()

bool te::da::UniqueKey::has ( const std::string & propertyName ) const

It verifies if Property is associated to the unique key.

Parameters

propertyName The Property name to be verified.

Returns: True if Property is associated to the unique key, false otherwise.

◆ operator=()

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

Assignment operator.

The new object will not have an assigned DataSetType.

Parameters

rhs	Right-hand-side instance.

Returns: A reference to this.

◆ replace()

void te::da::UniqueKey::replace	(	const std::string &	propName,
		const te::dt::Property *	pp
	)

◆ setAssociatedIndex()

void te::da::UniqueKey::setAssociatedIndex ( const Index * idx )

It sets the associated index.

Parameters

idx	A index associated to the unique key.

◆ setDataSetType()

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.

◆ setId()

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.

◆ setName()

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

inlinevirtualinherited

It sets the constraint name.

Parameters

name	The constraint name.
