Member Function Documentation

◆ AddType() [1/2]

void StdStorage_TypeData::AddType ( const TCollection_AsciiString aTypeName,
const Standard_Integer  aTypeNum 
)

Add a type to the list in case of reading data.

◆ AddType() [2/2]

Standard_Integer StdStorage_TypeData::AddType ( const Handle< StdObjMgt_Persistent > &  aPObj)

Add a type of the persistent object in case of writing data.

◆ Clear()

void StdStorage_TypeData::Clear ( )

Unregisters all types.

◆ ClearErrorStatus()

void StdStorage_TypeData::ClearErrorStatus ( )

Clears error status.

◆ ErrorStatus()

Storage_Error StdStorage_TypeData::ErrorStatus ( ) const

Returns a status of the latest call to Read / Write functions.

◆ ErrorStatusExtension()

TCollection_AsciiString StdStorage_TypeData::ErrorStatusExtension ( ) const

Returns an error message if any of the latest call to Read / Write functions.

◆ Instantiator()

StdObjMgt_Persistent::Instantiator StdStorage_TypeData::Instantiator ( const Standard_Integer  aTypeNum) const

Returns a persistent object instantiator of <aTypeName>

◆ IsType()

Standard_Boolean StdStorage_TypeData::IsType ( const TCollection_AsciiString aName) const

Checks if <aName> is a registered type.

◆ NumberOfTypes()

Standard_Integer StdStorage_TypeData::NumberOfTypes ( ) const

Returns the number of registered types.

◆ Read()

Standard_Boolean StdStorage_TypeData::Read ( Storage_BaseDriver theDriver)

Reads the type data section from the container defined by theDriver. Returns Standard_True in case of success. Otherwise, one need to get an error code and description using ErrorStatus and ErrorStatusExtension functions correspondingly.

◆ Type() [1/2]

TCollection_AsciiString StdStorage_TypeData::Type ( const Standard_Integer  aTypeNum) const

Returns the name of the type with number <aTypeNum>

◆ Type() [2/2]

Standard_Integer StdStorage_TypeData::Type ( const TCollection_AsciiString aTypeName) const

Returns the name of the type with number <aTypeNum>

◆ Types()

Handle< TColStd_HSequenceOfAsciiString > StdStorage_TypeData::Types ( ) const

Returns a sequence of all registered types.

◆ Write()

Standard_Boolean StdStorage_TypeData::Write ( Storage_BaseDriver theDriver)

Writes the type data section to the container defined by theDriver. Returns Standard_True in case of success. Otherwise, one need to get an error code and description using ErrorStatus and ErrorStatusExtension functions correspondingly.
