Detailed Description

It models a property definition.

The class Property defines information about the values of a given property. This includes:

The data type associated to the property;
Any restrictions on the values of the property;

Constructor & Destructor Documentation

te::dt::Property::Property	(	const std::string &	name,
		int	datatype,
		unsigned int	id = `0`,
		Property *	parent = `0`
	)

It initializes a new Property.

Parameters

name	The Property name.
datatype	The property data type.
id	The property identifier.
parent	A reference to the parent Property of the new object.

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

Definition at line 29 of file Property.cpp.

te::dt::Property::Property ( const Property & rhs )

Copy constructor.

Parameters

rhs	The right-hand-side copy used to copy from.

Note: Copy constructor doesn't preserve parent relationship.

Definition at line 40 of file Property.cpp.

virtual te::dt::Property::~Property ( )

inlinevirtual

Virtual destructor.

virtual Property* te::dt::Property::clone ( ) const

pure virtual

It returns a clone of the object.

The new Property may not have associations to other elements. For example, a DataSetType associated to a DataSourceCatalog when cloned will not have the clone associate to the same DataSourceCatalog.

Returns: A clone of the object.

Implemented in te::da::DataSetType, te::dt::CompositeProperty, te::rst::RasterProperty, te::gm::GeometryProperty, te::dt::SimpleProperty, te::dt::StringProperty, te::dt::DateTimeProperty, te::dt::NumericProperty, te::dt::ArrayProperty, te::dt::ByteArrayProperty, and te::dt::BitProperty.

unsigned int te::dt::Property::getId ( ) const

inline

It returns the property identifier.

Returns: A number used to identify the property.

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

const std::string& te::dt::Property::getName ( ) const

inline

It returns the property name.

Returns: The property name.

Note: For DataSetTypes the name can have namespace prefix or schema name prefix, it will depend on the data source implementation.

Definition at line 126 of file Property.h.

Property* te::dt::Property::getParent ( ) const

inline

It returns the parent of this property, or NULL, if it doesn't have one.

Returns: The parent of this property, or NULL, if it doesn't have one.

int te::dt::Property::getType ( ) const

inline

It returns the property data type.

Returns: The property data type.

virtual bool te::dt::Property::has ( Property * p ) const

pure virtual

It checks if the Property "p" is associated to this property or any other parent.

This method can be used to ask if a given Property belongs to a more complex type (like: CompositeProperty or DataSetType).

Parameters

p	The Property we are checking.

Returns: True if the given Property "p" is associated to to this Property, otherwise, returns false.

Implemented in te::dt::CompositeProperty, and te::dt::SimpleProperty.

te::dt::Property & te::dt::Property::operator= ( const Property & rhs )

Assignment operator.

Parameters

rhs	The right-hand-side copy used to copy from.

Returns: A reference to this object.

Note: Assignment operator doesn't preserve parent relationship.

Definition at line 48 of file Property.cpp.

References m_id, m_name, and m_type.

Referenced by te::dt::CompositeProperty::operator=(), and te::dt::SimpleProperty::operator=().

void te::dt::Property::setId ( unsigned int id )

inline

It sets the property identifier.

Parameters

id	A number used to identify the property.

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

void te::dt::Property::setName ( const std::string & name )

inline

It sets the property name.

Parameters

name	The new property name.

Warning: Take care when calling this method for a DataSetType associated to a DataSourceCatalog. Prefer using the rename method on the DataSourceCatalog API instead of using this method.

Parameters

p	Teh parent property.
