makVre::DtAttributeData Class Reference

Detailed Description

This abstract class provides the interface for type-independent attribute data storage. It allows type-safe access to attribute values through dynamic casting and defines operations common to all attribute types.

Member Function Documentation

type()

virtual const std::string & makVre::DtAttributeData::type ( ) const

pure virtual

Gets the type name of this attribute data.

Returns

String representation of the data type

Implemented in makVre::DtAttributeDataType< T >.

typeHash()

virtual std::size_t makVre::DtAttributeData::typeHash ( ) const

pure virtual

Gets a hash of the type for faster comparisons.

Returns

Hash code for the data type

Implemented in makVre::DtAttributeDataType< T >.

as() [1/2]

template<typename T>

DtAttributeDataType< T > & makVre::DtAttributeData::as ( )

inline

Casts this attribute data to a specific type.

Template Parameters

T	The type to cast to

Returns

Reference to this object as the requested type

Note

No type checking is performed; use verifyType() first to ensure safety

as() [2/2]

template<typename T>

const DtAttributeDataType< T > & makVre::DtAttributeData::as ( ) const

inline

Casts this attribute data to a specific type (const version)

Template Parameters

T	The type to cast to

Returns

Const reference to this object as the requested type

Note

No type checking is performed; use verifyType() first to ensure safety

getAsString()

virtual std::string makVre::DtAttributeData::getAsString ( ) const

pure virtual

Gets the attribute value as a string.

Returns

String representation of the current value

Implemented in makVre::DtAttributeDataType< T >.

setFromString()

virtual bool makVre::DtAttributeData::setFromString ( const std::string & newValue )

pure virtual

Sets the attribute value from a string.

Parameters

newValue

String representation of the value to set

Returns

True if conversion and setting succeeded, false otherwise

Implemented in makVre::DtAttributeDataType< T >.

raw()

virtual const void * makVre::DtAttributeData::raw ( ) const

pure virtual

Gets a raw pointer to the attribute data.

Returns

Void pointer to the raw data

Implemented in makVre::DtAttributeDataType< T >.
