Feature Representation

In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Attributes), a Data File feature consists of the following attributes:

Attribute Name

Contents

data_file_data The line of text read from the source file or to be written to the destination file.
data_file_type The geometry type of the data file. This will always be data_file_none.
data_file_length Total number of bytes in data_file_data attribute. (Reader only)
data_file_number Line number of the text line within the file. (Reader only)
data_file_eol The end of line type identifier which will be read per source file and can be specified per feature and thus per destination data file.

Data File user attributes are not supported and all known format attributes have a fixed range of values except for the actual file data in data_file_data which is treated as as stream of raw bytes.
