Events
[ On Style Events | Connect Style Event ]
All On Style event listeners receive a single event object. Additionally, the event object also contains a 'target' property whose value is the object which fired the event.
Events
| Name | Event Object | Summary |
|---|---|---|
| onConnected | Triggered when successfully retrieved list of coverages. | |
| onConnectionFailed | {
error: < | Triggered when an error occurred. |

Property Details
<WCSCoverageDescription[]
WCSCoverageDescription[]An array of coverages offered by the WCS server.
<DimensionalDefinition[]
DimensionalDefinition[]Multiple dimensional definitions are usually used to filter data.
Sample:
var wcsConn = new WCSConnection();
wcsConn.multidimensionalDefinition = [];
wcsConn.multidimensionalDefinition.push(new DimensionalDefinition({
variableName: "Salinity",
dimensionName: "StdTime",
values: [1259625600000]
}));
<String
StringThe name of the WCS server.
<Object
ObjectKey-value pairs for URLs of different WCS operations:
- GetCapabilities
- DescribeCoverage
<String[]
