Reader Directives

The suffix shown is prefixed by the current <ReaderKeyword> in a mapping file.

By default, the <ReaderKeyword> for the C++ TFS Fixed Schema reader is TFS_FIXEDSCHEMA and the <ReaderKeyword> for the Java TFS Fixed Schema reader is com.mycompany.myformat.tfs_fixedschema.tfs_fixedschema.

DATASET

The value for this directive is the TFS Fixed Schema file to be read. A typical mapping file fragment specifying an input TFS Fixed Schema dataset looks like:

TFS_FIXEDSCHEMA_DATASET /usr/data/tfs_fixedschema/dataset.tfs

Required/Optional

Required

Workbench Parameter

Source Text Feature Store (TFS) Fixed Schema File(s)

ENCODING (C++ TFS Fixed Schema)

This optional specification controls which character encoding is used to interpret text attributes from the TFS_VARIABLESCHEMA file. If the value is not set, then the text attributes will all be interpreted using the system encoding.

Required/Optional

Optional

Mapping File Syntax

<ReaderKeyword>_ENCODING <encoding>

Parameter Description
<encoding>

ANSI - this means use the “current OS language”

Workbench Parameter

Character Encoding (optional)

SEARCH_ENVELOPE

Using the minimum and maximum x and y parameters, define a bounding box that will be used to filter the input features. Only features that interact with the bounding box are returned.

If all four coordinates of the search envelope are specified as 0, the search envelope will be disabled.

Mapping File Syntax

<ReaderKeyword>_SEARCH_ENVELOPE <minX> <minY> <maxX> <maxY>

Note: If all four coordinates of the search envelope are specified as zero, the search envelope will be disabled.

Required/Optional

Optional

Workbench Parameter

Minimum X, Minimum Y, Maximum X, Maximum Y

SEARCH_ENVELOPE_COORDINATE_SYSTEM

This directive specifies the coordinate system of the search envelope if it is different than the coordinate system of the data.

The COORDINATE_SYSTEM directive, which specifies the coordinate system associated with the data to be read, must always be set if the SEARCH_ENVELOPE_COORDINATE_SYSTEM directive is set.

If this directive is set, the minimum and maximum points of the search envelope are reprojected from the SEARCH_ENVELOPE_COORDINATE_SYSTEM to the reader COORDINATE_SYSTEM prior to applying the envelope.

Required/Optional

Optional

Mapping File Syntax

<ReaderKeyword>_SEARCH_ENVELOPE_COORDINATE_SYSTEM <coordinate system>

Workbench Parameter

Search Envelope Coordinate System

CLIP_TO_ENVELOPE

This directive specifies whether or not FME should clip features to the envelope specified in the SEARCH_ENVELOPE directive.

Values

YES | NO (default)

Mapping File Syntax

<ReaderKeyword>_CLIP_TO_ENVELOPE [yes | no]

Workbench Parameter

Clip To Envelope
