Transfer_Finder Class Referenceabstract

a Finder allows to map any kind of object as a Key for a Map. This works by defining, for a Hash Code, that of the real Key, not of the Finder which acts only as an intermediate. When a Map asks for the HashCode of a Finder, this one returns the code it has determined at creation time More...

Member Function Documentation

Handle< Standard_Transient > Transfer_Finder::Attribute ( const Standard_CString  name) const

Returns an attribute from its name. Null Handle if not recorded (whatever Transient, Integer, Real ...)

Interface_ParamType Transfer_Finder::AttributeType ( const Standard_CString  name) const

Returns the type of an attribute : ParamInt , ParamReal , ParamText (String) , ParamIdent (any) or ParamVoid (not recorded)

Returns the exhaustive list of attributes.

virtual Standard_Boolean Transfer_Finder::Equates ( const Handle< Transfer_Finder > &  other) const
pure virtual

Specific testof equallity : to be defined by each sub-class, must be False if Finders have not the same true Type, else their contents must be compared.

Implemented in TransferBRep_OrientedShapeMapper, TransferBRep_ShapeMapper, and Transfer_TransientMapper.

Standard_Boolean Transfer_Finder::GetAttribute ( const Standard_CString  name,
const Handle< Standard_Type > &  type,
Handle< Standard_Transient > &  val 
) const

Returns an attribute from its name, filtered by a type If no attribute has this name, or if it is not kind of this type, <val> is Null and returned value is False Else, it is True.

void Transfer_Finder::GetAttributes ( const Handle< Transfer_Finder > &  other,
const Standard_CString  fromname = "",
const Standard_Boolean  copied = Standard_True 
)

Gets the list of attributes from <other>, by copying it By default, considers all the attributes from <other> If <fromname> is given, considers only the attributes with name beginning by <fromname>

For each attribute, if <copied> is True (D), its value is also copied if it is a basic type (Integer,Real,String), else it remains shared between <other> and <me>

These new attributes are added to the existing ones in <me>, in case of same name, they replace the existing ones

Standard_Integer Transfer_Finder::GetHashCode ( ) const

void Transfer_Finder::SameAttributes ( const Handle< Transfer_Finder > &  other)

Gets the list of attributes from <other>, as such, i.e. not copied : attributes are shared, any attribute edited, added, or removed in <other> is also in <me> and vice versa The former list of attributes of <me> is dropped.

void Transfer_Finder::SetAttribute ( const Standard_CString  name,
const Handle< Standard_Transient > &  val 
)

Adds an attribute with a given name (replaces the former one with the same name if already exists)

void Transfer_Finder::SetHashCode ( const Standard_Integer  code)
protected

Stores the HashCode which corresponds to the Value given to create the Mapper.

void Transfer_Finder::SetIntegerAttribute ( const Standard_CString  name,
const Standard_Integer  val 
)

Adds an integer value for an attribute.

void Transfer_Finder::SetRealAttribute ( const Standard_CString  name,
const Standard_Real  val 
)

Adds a real value for an attribute.

void Transfer_Finder::SetStringAttribute ( const Standard_CString  name,
const Standard_CString  val 
)

Adds a String value for an attribute.

Standard_CString Transfer_Finder::StringAttribute ( const Standard_CString  name) const

Returns a String attribute from its name. "" if not recorded.

virtual Handle< Standard_Type > Transfer_Finder::ValueType ( ) const
virtual

Returns the Type of the Value. By default, returns the DynamicType of <me>, but can be redefined.
