Methods

readFeature(source, options){Feature} inherited

format/XMLFeature.js, line 45

Read a single feature.

Name	Type	Description
source	Document | Element | Object | string	Source.
options	Read options. Name Type Description dataProjection ProjectionLike | undefined Projection of the data we are reading. If not provided, the projection will be derived from the data (where possible) or the dataProjection of the format is assigned (where set). If the projection can not be derived from the data and if no dataProjection is set for a format, the features will not be reprojected. extent Extent | undefined Tile extent in map units of the tile being read. This is only required when reading data with tile pixels as geometry units. When configured, a dataProjection with TILE_PIXELS as units and the tile's pixel extent as extent needs to be provided. featureProjection ProjectionLike | undefined Projection of the feature geometries created by the format reader. If not provided, features will be returned in the dataProjection.

Returns:

Feature.

readFeatureCollectionMetadata(source){FeatureCollectionMetadata | undefined}

format/WFS.js, line 400

Read feature collection metadata of the source.

Name	Type	Description
source	Document | Element | Object | string	Source.

Returns:

FeatureCollection metadata.

readFeatures(source, options){Array<Feature>} inherited

format/XMLFeature.js, line 93

Read all features from a feature collection.

Name	Type	Description
source	Document | Element | Object | string	Source.
options	Options. Name Type Description dataProjection ProjectionLike | undefined Projection of the data we are reading. If not provided, the projection will be derived from the data (where possible) or the dataProjection of the format is assigned (where set). If the projection can not be derived from the data and if no dataProjection is set for a format, the features will not be reprojected. extent Extent | undefined Tile extent in map units of the tile being read. This is only required when reading data with tile pixels as geometry units. When configured, a dataProjection with TILE_PIXELS as units and the tile's pixel extent as extent needs to be provided. featureProjection ProjectionLike | undefined Projection of the feature geometries created by the format reader. If not provided, features will be returned in the dataProjection.

Returns:

Features.

readProjection(source){Projection} inherited

format/XMLFeature.js, line 194

Read the projection from the source.

Name	Type	Description
source	Document | Element | Object | string	Source.

Returns:

Projection.

readTransactionResponse(source){TransactionResponse | undefined}

format/WFS.js, line 374

Read transaction response of the source.

Name	Type	Description
source	Document | Element | Object | string	Source.

Returns:

Transaction response.

writeFeatures(features, options){string} inherited

format/XMLFeature.js, line 258

Encode an array of features as string.

Name	Type	Description
features	Array<Feature>	Features.
options	Write options. Name Type Description dataProjection ProjectionLike | undefined Projection of the data we are writing. If not provided, the dataProjection of the format is assigned (where set). If no dataProjection is set for a format, the features will be returned in the featureProjection. featureProjection ProjectionLike | undefined Projection of the feature geometries that will be serialized by the format writer. If not provided, geometries are assumed to be in the dataProjection if that is set; in other words, they are not transformed. rightHanded boolean | undefined When writing geometries, follow the right-hand rule for linear ring orientation. This means that polygons will have counter-clockwise exterior rings and clockwise interior rings. By default, coordinates are serialized as they are provided at construction. If true, the right-hand rule will be applied. If false, the left-hand rule will be applied (clockwise for exterior and counter-clockwise for interior rings). Note that not all formats support this. The GeoJSON format does use this property when writing geometries. decimals number | undefined Maximum number of decimal places for coordinates. Coordinates are stored internally as floats, but floating-point arithmetic can create coordinates with a large number of decimal places, not generally wanted on output. Set a number here to round coordinates. Can also be used to ensure that coordinates read in can be written back out with the same number of decimals. Default is no rounding.

Returns:

Result.

writeGetFeature(options){Node}

format/WFS.js, line 487

Encode format as WFS GetFeature and return the Node.

Name	Type	Description
featureNS	string	The namespace URI used for features.
featurePrefix	string	The prefix for the feature namespace.
featureTypes	Array.<(string|module:ol/format/WFS~FeatureType)>	The feature type names or FeatureType objects to define a unique bbox filter per feature type name (in this case, options bbox and geometryName are ignored.).
srsName	string | undefined	SRS name. No srsName attribute will be set on geometries when this is not provided.
handle	string | undefined	Handle.
outputFormat	string | undefined	Output format.
maxFeatures	number | undefined	Maximum number of features to fetch.
geometryName	string | undefined	Geometry name to use in a BBOX filter.
propertyNames	Array.<string> | undefined	Optional list of property names to serialize.
viewParams	string | undefined	viewParams GeoServer vendor parameter.
startIndex	number | undefined	Start index to use for WFS paging. This is a WFS 2.0 feature backported to WFS 1.1.0 by some Web Feature Services.
count	number | undefined	Number of features to retrieve when paging. This is a WFS 2.0 feature backported to WFS 1.1.0 by some Web Feature Services. Please note that some Web Feature Services have repurposed maxfeatures instead.
bbox	Extent | undefined	Extent to use for the BBOX filter. The geometryName option must be set.
filter	Filter | undefined	Filter condition. See ol/format/filter for more information.
resultType	string | undefined	Indicates what response should be returned, e.g. hits only includes the numberOfFeatures attribute in the response and no features.

Returns:

Result.

writeTransaction(inserts, updates, deletes, options){Node}

format/WFS.js, line 603

Encode format as WFS Transaction and return the Node.

Name	Type	Description
inserts	Array<Feature>	The features to insert.
updates	Array<Feature>	The features to update.
deletes	Array<Feature>	The features to delete.
options	Write options. Name Type Description featureNS string The namespace URI used for features. featurePrefix string The prefix for the feature namespace. featureType string The feature type name. srsName string | undefined SRS name. No srsName attribute will be set on geometries when this is not provided. handle string | undefined Handle. hasZ boolean | undefined Must be set to true if the transaction is for a 3D layer. This will allow the Z coordinate to be included in the transaction. nativeElements Array.<Object> Native elements. Currently not supported. gmlOptions Options | undefined GML options for the WFS transaction writer. version string (defaults to '1.1.0') WFS version to use for the transaction. Can be either 1.0.0, 1.1.0 or 2.0.0.

Returns:

Result.
