Importing data from a string or a file.
This data model imports data from a string or a file. The data can either be in a CSV (comma separated values) format or in an XML format as described by the libgda-array.dtd DTD (It is also possible to import data from an already-build XML tree validated against that DTD). The caller must decide, upon construction, if the new DataModelImport must support random access or simply cursor based access. Random access makes it easier to use the resulting data model but consumes more memory as all the data is copied in memory, and this is thus not suitable for large data sets. Note that importing from an already-built XML tree will always result in a random access data model.
Various import options can be specified using parameters in a Set object. The available options depend on the format of the imported data listed here:
