Summary

OpenLayers.Format.Filter.v1	Superclass for Filter version 1 parsers.
Properties
namespaces	{Object} Mapping of namespace aliases to namespace URIs.
defaultPrefix
schemaLocation	{String} Schema location for a particular minor version.
Constructor
OpenLayers.Format.Filter.v1	Instances of this class are not created directly.
Functions and Properties
read
readers	Contains public functions, grouped by namespace prefix, that will be applied when a namespaced node is found matching the function name.
readSpatial	Read a {OpenLayers.Filter.Spatial} filter.
readOgcExpression	Limited support for OGC expressions.
write
writers	As a compliment to the readers property, this structure contains public writing functions grouped by namespace alias and named like the node names they produce.
getFilterType
filterMap	{Object} Contains a member for each filter type.

Properties

namespaces

{Object} Mapping of namespace aliases to namespace URIs.

defaultPrefix

schemaLocation

{String} Schema location for a particular minor version.

Constructor

OpenLayers.Format.Filter.v1

Instances of this class are not created directly. Use the OpenLayers.Format.Filter constructor instead.

Parameters

options

{Object} An optional object whose properties will be set on this instance.

Functions and Properties

read

read: function( data )

Parameters

data	{DOMElement} A Filter document element.

Returns

{OpenLayers.Filter} A filter object.

readers

Contains public functions, grouped by namespace prefix, that will be applied when a namespaced node is found matching the function name. The function will be applied in the scope of this parser with two arguments: the node being read and a context object passed from the parent.

readSpatial

readSpatial: function( node,
obj,
type )

Read a {OpenLayers.Filter.Spatial} filter.

Parameters

node	{DOMElement} A DOM element that contains an ogc:expression.
obj	{Object} The target object.
type	{String} One of the OpenLayers.Filter.Spatial.* constants.

Returns

{OpenLayers.Filter.Spatial} The created filter.

readOgcExpression

readOgcExpression: function( node )

Limited support for OGC expressions.

Parameters

node	{DOMElement} A DOM element that contains an ogc:expression.

Returns

{String} A value to be used in a symbolizer.

write

write: function( filter )

Parameters

filter

{OpenLayers.Filter} A filter object.

Returns

{DOMElement} An ogc:Filter element.

writers

As a compliment to the readers property, this structure contains public writing functions grouped by namespace alias and named like the node names they produce.

getFilterType

getFilterType: function( filter )

filterMap

{Object} Contains a member for each filter type. Values are node names for corresponding OGC Filter child elements.
