handleRESTRequest

byte[] handleRESTRequest(String capabilities,
                         String resourceName,
                         String operationName,
                         String operationInput,
                         String outputFormat,

                         throws IOException,
                                AutomationException

Handles REST requests for SOE.

This method is invoked by ArcGIS Server's REST handler, which intercepts client's request (in URL form), parses it and passes it on to this method in form of parameter values.

The REST SOE developer must add logic to use these parameter values to determine which resource/operation is being requested and accordingly handle these requests and generate responses in the output format indicated by the "outputFormat" parameter. For more information on developing REST SOEs, please consult the Java ArcObjects Developer Guide.

Samples: Samples > Server Object Extensions section

Parameters:

capabilities - The capabilities supported by the SOE. An admin can choose which capabilities are enabled on a particular SOE (in ArcGIS Manager or ArcCatalog), based on certain criteria such as security roles. This list of allowed capabilities is then sent to this method, at runtime, as a comma separated list. (in)

resourceName - Name of the resource being addressed. If empty, its assumed that root resource is being addressed. (in)

operationName - Name of the operation being invoked. If empty, description of resource is returned. (in)

operationInput - Input parameters, in form of comma separated list, to the operation specified by operationName parameter. (in)

outputFormat - OutputFormat of operation. Possible formats are JSON, HTML, AMF, etc. (in)

requestProperties - The requestProperties (in)

responseProperties - The responseProperties (out)

Returns:

Output generated by the SOE

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getSchema

String getSchema()
                 throws IOException,
                        AutomationException

This method returns the resource hierarchy of a REST based SOE. This hierarchy is in JSON format as shown in the example below:

For an SOE that has a root resource (called "root") with one operation ("operation0"), and 2 sub-resources with one operation each ("operation1" and "operation2" respectively), the schema would look like:

 {
   "name": "MyRESTSOE",
   "description": "My REST SOE with 3 resources and 1 operation each.",
   "isCollection": false,
   "operations": [
   {
      "name": "operation0",
      "parameters": ["param01"],
      "supportedOutputFormats": ["json"]
    }
 ],
 "resources": [
  {
      "name": "subresource1",
      "description": "Sub Resource 1",
      "isCollection": true,
      "operations": [
       {
          "name": "operation1",
          "parameters": ["param10", "param11"],
          "supportedOutputFormats": ["json"]
       }
    ]
  },
  {
      "name": "subresource2",
      "description": "Sub Resource 2",
      "isCollection": true,
      "operations": [
       {
          "name": "operation2",
          "parameters": ["param20", "param21"],
          "supportedOutputFormats": ["json"]
       }
    ]
  }
 ]
}

Returns:

resource hierarchy of REST SOE, as String

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
