Multi-Writer Feature Representation

Special FME feature attributes are used to hold Multi-Writer parameters.

Keyword	Value
multi_writer_id	This attribute holds the identifier of the individual writer for which the feature is destined. This corresponds to the key enclosed in {} in the MULTI_READER_TYPE{key} keyword. If desired, the MULTI_WRITER_ID_ATTRIBUTE keyword can be used to override this, so that another attribute can be used instead. Example: GIF
multi_writer_row	If the multi_writer_id attribute is not present, this attribute holds the row part of the row,column identifier of the individual identifier that the feature is destined for. Example: 1
multi_writer_column	If the multi_writer_id attribute is not present, this attribute holds the column part of the row,column identifier of the individual writer that the feature is destined for. Example: 1

Keyword

Value

multi_writer_id

This attribute holds the identifier of the individual writer for which the feature is destined. This corresponds to the key enclosed in {} in the MULTI_READER_TYPE{key} keyword.

If desired, the MULTI_WRITER_ID_ATTRIBUTE keyword can be used to override this, so that another attribute can be used instead.

Example: GIF

multi_writer_row

If the multi_writer_id attribute is not present, this attribute holds the row part of the row,column identifier of the individual identifier that the feature is destined for.

Example: 1

multi_writer_column

If the multi_writer_id attribute is not present, this attribute holds the column part of the row,column identifier of the individual writer that the feature is destined for.

Example: 1

Note: If neither the multi_writer_id or multi_writer_row and multi_writer_column attributes are present, the Multi-Writer will treat the feature as if the multi_writer_id was set to “NULL”.
