Recorder

• If the mode is RECORD_PASS_THROUGH, the transformer will record each feature it receives and immediately pass it through to the rest of FME for further processing.
• If the mode is RECORD, the transformer will record each feature it receives but wait until the end of translation before it sends all recorded features through to the rest of FME for processing. This method is useful because if one of the features causes the translation to fail, the feature file will be complete and usable, whereas if a failure occurs when using the RECORD_PASS_THROUGH mode, the feature file may not be usable.

Specifies the output .ffs file.

Provides a level of password protection for the created file. Before the file can be read, the password will have to be reentered.

If set to Yes, creates and outputs a spatial and feature index for each feature store. The index has the same base name as the FFS file, but will have an .fsi extension. Spatial Indexes are needed if the FFS file is later used as the source for spatial queries or feature types by the FFS reader.

Note: If a spatial index is created, Compression Method and Compression Level are ignored; to allow for efficient random access, a non-compressed .ffs file is output.

• LZ4 (fastest) (default) – Uses a fast algorithm to reduce the size of the recording. Results in larger file sizes than Zstandard compression.
• Zstandard – Reduces the size of the recording with a general-purpose algorithm. Compression Level is used to determine the tradeoff between writing speed and file size.
• None – Does not reduce the size of the recording.

Note: Compression is best suited for sequential access; to allow for efficient random access for spatial operations, it is disabled and set to None if Create Spatial Index set to Yes.

Reduces the size of the output recording.

Higher numbers mean more compression and smaller output files; and additional CPU is expended to create files.

Note: Compression is best suited for sequential access and is disabled if Create Spatial Index set to Yes to allow for efficient random access for spatial operations.

If Yes, a spatial index (.fsi) file is written alongside the output .ffs file. An index allows for efficient spatial queries, such as clipping to a search envelope or finding a specified feature.

Note: If a spatial index is created, Compression Level is ignored, and a non-compressed .ffs file is output to allow for efficient random access.

When this option is set to Yes, schemas will be recorded and stored in the output FFS file. If it is set to No (default), schemas will not be passed along to the output file.

Metadata includes feature types, geometry types, feature count, and extents.

• Yes: Additional metadata will be recorded and stored in the output FFS file.
• No (default): Metadata will not be stored in the output file.

Sets the feature type for the feature inside the FFS file. If no attribute is given, a default feature type is provided.

Using the Text Editor

The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.

Using the Arithmetic Editor

The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.

Conditional Values

Set values depending on one or more test conditions that either pass or fail.

Content

Expressions and strings can include a number of functions, characters, parameters, and more.

When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.

Content Types

String Functions	These functions manipulate and format strings.
Special Characters	A set of control characters is available in the Text Editor.

Date/Time Functions	Date and time functions are available in the Text Editor.
Math Operators	These operators are available in the Arithmetic Editor.
FME Feature Functions	These return primarily feature-specific values.
FME Parameters	FME and workspace-specific parameters may be used.
Creating and Modifying User Parameters	Create your own editable parameters.

Note: Not all tools are available in all transformers.
