A factory interface providing methods for the creation of Grid.DRegularGridReaderBase instances for reading data provided in a particular storage format.
◆ getObjectID()
int CDPL.Grid.DRegularGridInputHandler.getObjectID |
( |
| ) |
|
Returns the numeric identifier (ID) of the wrapped C++ class instance.
Different Python DRegularGridInputHandler instances may reference the same underlying C++ class instance. The commonly used Python expression a is not b
thus cannot tell reliably whether the two DRegularGridInputHandler instances a and b reference different C++ objects. The numeric identifier returned by this method allows to correctly implement such an identity test via the simple expression a.getObjectID() != b.getObjectID()
.
- Returns
- The numeric ID of the internally referenced C++ class instance.
◆ getDataFormat()
Returns a Base.DataFormat object that provides information about the handled input data format.
- Returns
- A Base.DataFormat object that provides information about the handled data format.
◆ createReader() [1/2]
◆ createReader() [2/2]
Creates a DRegularGridReaderBase instance that will read the data from the file specified by file_name.
- Parameters
-
file_name | The full path of the file to read from. |
mode | Flags specifying the file open-mode. |
- Returns
- The created DRegularGridReaderBase instance.
