This interface is the entry point for the import filter code to instantiate other, more specialized interfaces. The life cycles of any specialized interfaces returned from this interface shall be managed by the implementor of this interface.
The implementer of this interface may wrap a backend document store that needs to be populated.
|
pure virtual |
Append a sheet with a specified sheet position index and name and return an interface for importing its content. The implementor can use a call to this method as a signal to create and append a new sheet instance to the document store.
sheet_index | position index of the sheet to be appended. It is 0-based i.e. the first sheet to be appended will have an index value of 0. |
name | sheet name. |
nullptr
if the implementor doesn't support it. Note, however, that if the implementor doesn't support this interface, no cell values will get imported. Implemented in orcus::spreadsheet::import_factory.
|
virtual |
Obtain an optional interface for pivot cache definition import for a specified cache ID. In case a pivot cache alrady exists for the passed ID, the implementor should overwrite the existing cache with a brand-new cache instance.
cache_id | numeric ID associated with the pivot cache. |
nullptr
if the implementor doesn't support pivot cache import. Reimplemented in orcus::spreadsheet::import_factory.
|
virtual |
Obtain an optional interface for pivot cache records import for a specified cache ID.
cache_id | numeric ID associated with the pivot cache. |
nullptr
if the implementor doesn't support pivot cache import. Reimplemented in orcus::spreadsheet::import_factory.
|
pure virtual |
The import filter calls this method after completing its import, to give the implementor a chance to perform post-processing.
Implemented in orcus::spreadsheet::import_factory.
|
virtual |
Obtain an optional interface for global settings, which the import filter uses to specify global filter settings that may affect how certain values and properties should be processed. The implementor can use this interface to decide how to process relevant values and properties.
nullptr
if the implementor doesn't support it. Reimplemented in orcus::spreadsheet::import_factory.
|
virtual |
Obtain an optional interface for importing global named expressions.
Note that import_sheet also provides the same interface, but its interface is for importing sheet-local named expressions.
nullptr
if the implementor doesn't support it. Reimplemented in orcus::spreadsheet::import_factory.
|
virtual |
Obtain an optional interface for resolving cell and cell-range references from string values.
cxt | context in which the formula expression containing the references to be resolved occurs. |
nullptr
if the implementor doesn't support it. Reimplemented in orcus::spreadsheet::import_factory.
|
virtual |
Obtain an optional interface for importing shared strings for string cells. Implementing this interface is required in order to import string cell values.
nullptr
if the implementor doesn't support it. Reimplemented in orcus::spreadsheet::import_factory.
|
pure virtual |
Retrieve a sheet instance by a specified numerical sheet index.
sheet_index | sheet index. |
nullptr
if no sheet instance exists at the specified sheet index. Implemented in orcus::spreadsheet::import_factory.
|
pure virtual |
Get a sheet instance by name. The import filter may use this method to get access to an existing sheet after it has been created.
name | sheet name. |
nullptr
if no sheet instance exists by the specified name. Implemented in orcus::spreadsheet::import_factory.
|
virtual |
Obtain an optional interface for importing styles used to add formatting properties to cell values.
nullptr
if the implementor doesn't support it. Reimplemented in orcus::spreadsheet::import_factory.
