Methods

readFeature(source, opt_options){module:ol/Feature~Feature} inherited

format/XMLFeature.js, line 44

Read a single feature.

Name	Type	Description
source	Document | Element | Object | string	Source.
options	Read options. Name Type Description dataProjection module:ol/proj~ProjectionLike 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 module:ol/extent~Extent 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 module:ol/proj~ProjectionLike Projection of the feature geometries created by the format reader. If not provided, features will be returned in the dataProjection.

Returns:

Feature.

readFeatureCollectionMetadata(source){module:ol/format/WFS~FeatureCollectionMetadata|undefined}

format/WFS.js, line 394

Read feature collection metadata of the source.

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

Returns:

FeatureCollection metadata.

readFeatures(source, opt_options){Array.<module:ol/Feature~Feature>} inherited

format/XMLFeature.js, line 94

Read all features from a feature collection.

Name	Type	Description
source	Document | Element | Object | string	Source.
options	Options. Name Type Description dataProjection module:ol/proj~ProjectionLike 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 module:ol/extent~Extent 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 module:ol/proj~ProjectionLike Projection of the feature geometries created by the format reader. If not provided, features will be returned in the dataProjection.

Returns:

Features.

readProjection(source){module:ol/proj/Projection~Projection} inherited

format/XMLFeature.js, line 197

Read the projection from the source.

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

Returns:

Projection.

readTransactionResponse(source){module:ol/format/WFS~TransactionResponse|undefined}

format/WFS.js, line 369

Read transaction response of the source.

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

Returns:

Transaction response.

writeFeatures(features, opt_options){string} inherited

format/XMLFeature.js, line 258

Encode an array of features as string.

Name	Type	Description
features	Array.<module:ol/Feature~Feature>	Features.
options	Write options. Name Type Description dataProjection module:ol/proj~ProjectionLike 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 module:ol/proj~ProjectionLike 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 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 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 480

Encode format as WFS GetFeature and return the Node.

Name	Type	Description
options	Options. 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 SRS name. No srsName attribute will be set on geometries when this is not provided. handle string Handle. outputFormat string Output format. maxFeatures number Maximum number of features to fetch. geometryName string Geometry name to use in a BBOX filter. propertyNames Array.<string> Optional list of property names to serialize. viewParams string viewParams GeoServer vendor parameter. startIndex number 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 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 module:ol/extent~Extent Extent to use for the BBOX filter. The geometryName option must be set. filter module:ol/format/filter/Filter~Filter Filter condition. See module:ol/format/Filter for more information. resultType string 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 590

Encode format as WFS Transaction and return the Node.

Name	Type	Description
inserts	Array.<module:ol/Feature~Feature>	The features to insert.
updates	Array.<module:ol/Feature~Feature>	The features to update.
deletes	Array.<module:ol/Feature~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 SRS name. No srsName attribute will be set on geometries when this is not provided. handle string Handle. hasZ boolean 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 module:ol/format/GMLBase~Options 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.
