Function Detail

GetType

virtual int GetType();

Returns the type of this value.

GetNodeSet

virtual XNodeSet GetNodeSet();

Returns a node-set represented by this value.

Returns:: the node-set represented by this value

GetBoolean

virtual bool GetBoolean();

Returns a boolean represented by this value.

It is an error if this value does not represent a boolean (that is, has the type other than CValue::typeBoolean ).

Returns:: the boolean represented by this value

GetNumber

virtual CNumber GetNumber();

Returns a number represented by this value.

It is an error if this value does not represent a number (that is, has the type other than CValue::typeNumber ).

Returns:: the number represented by this value

GetString

virtual CString GetString();

Returns a string represented by this value.

It is an error if this value does not represent a string (that is, has the type other than CValue::typeString ).

Returns:: the string represented by this value
