List of all members.

## Detailed Description

The IReaderImp class is a concrete implementation class for interface IReader. The IReader interface provides a forward-only, read-only iterator for reading data. Because the initial position of the IReader is prior to the first item, you must call ReadNext to begin accessing any data.

## Public Member Functions
System::Void | Close ()
| Closes the IFeatureReader object, freeing any resources it may be holding.
System::Boolean | GetBoolean (System::String *name)
| Gets the Boolean value of the specified property. No conversion is performed, thus the property must be DataType_Boolean or an exception is thrown.
System::Byte | GetByte (System::String *name)
| Gets the byte value of the specified property. No conversion is performed, thus the property must be DataType_Byte or an exception is thrown.
System::DateTime | GetDateTime (System::String *name)
| Gets the date and time value of the specified property. No conversion is performed, thus the property must be DataType_DateTime or an exception is thrown.
System::Double | GetDouble (System::String *name)
| Gets the double-precision floating point value of the specified property. No conversion is performed, thus the property must be DataType_Double or an exception is thrown.
System::Byte | GetGeometry (System::String *name)[]
| Gets the geometry value of the specified property as a byte array in FGF format. Because no conversion is performed, the property must be of Geometric type; otherwise, an exception is thrown.
System::Int16 | GetInt16 (System::String *name)
| Gets the 16-bit integer value of the specified property. No conversion is performed, thus the property must be DataType_Int16 or an exception is thrown.
System::Int32 | GetInt32 (System::String *name)
| Gets the 32-bit integer value of the specified property. No conversion is performed, thus the property must be DataType_Int32 or an exception is thrown.
System::Int64 | GetInt64 (System::String *name)
| Gets the 64-bit integer value of the specified property. No conversion is performed, thus the property must be DataType_Int64 or an exception is thrown.
OSGeo::FDO::Expression::LOBValue * | GetLOB (System::String *name)
| Gets a LOBValue reference. The LOB is fully read in and data available. Because no conversion is performed, the property must be DataType_BLOB or DataType_CLOB etc. (a LOB type).
OSGeo::FDO::Common::IStreamReader * | GetLOBStreamReader (System::String *name)
| Gets a reference of the specified LOB property as a BLOBStreamReader or CLOBStreamReader etc. to allow reading in blocks of data. Because no conversion is performed, the property must be DataType_BLOB or DataType_CLOB etc. (a LOB type) Cast the IStreamReader to the appropiate LOB Stream Reader.
OSGeo::FDO::Raster::IRaster * | GetRaster (System::String *name)
| Gets the raster object of the specified property. Because no conversion is performed, the property must be of Raster type; otherwise, an exception is thrown.
System::Single | GetSingle (System::String *name)
| Gets the Single floating point value of the specified property. No conversion is performed, thus the property must be DataType_Single or an exception is thrown.
System::String * | GetString (System::String *name)
| Gets the string value of the specified property. No conversion is performed, thus the property must be DataType_String or an exception is thrown.
System::Boolean | IsNull (System::String *name)
| Returns true if the value of the specified property is null.
System::Boolean | ReadNext ()
| Advances the reader to the next item and returns true if there is another object to read or false if reading is complete. The default position of the reader is prior to the first item. Thus you must call ReadNext to begin accessing any data.
