Enum DSProtocol

      extended by com.smartgwt.client.types.DSProtocol
All Implemented Interfaces:
ValueEnum, java.io.Serializable, java.lang.Comparable<DSProtocol>

public enum DSProtocol
extends java.lang.Enum<DSProtocol>
implements ValueEnum

dataProtocol affects how the data in the DSRequest (data) is sent to the dataURL. Listed below are the valid values for dataProtocol and their behavior.

Note that, when using the Smart GWT server, data is automatically translated from JavaScript to Java according to the rules described here; dataProtocol does not apply and is ignored.

If you are integrating with a REST server that requires the more obscure httpMethods of "PUT", "DELETE" or "HEAD", you can specify these httpMethod settings via requestProperties. dataProtocol settings that mention "GET" or "POST" are compatible with these additional HTTP methods as well. Typical operationBindings for a REST server that uses "PUT" and "DELETE" are as follows:

     operationBindings:[
        {operationType:"fetch", dataProtocol:"getParams"},
        {operationType:"add", dataProtocol:"postParams"},
        {operationType:"remove", dataProtocol:"getParams", requestProperties:{httpMethod:"DELETE"}},
        {operationType:"update", dataProtocol:"postParams", requestProperties:{httpMethod:"PUT"}}
     ],
  


Enum Constant Summary
CLIENTCUSTOM
          This setting entirely bypasses the Smart GWT comm system.
GETPARAMS
          Data is added to the dataURL, with each property in the data becoming an HTTP parameter, eg http://service.com/search?keyword=foo
POSTMESSAGE
          dsRequest.data is assumed to be a String set up by DataSource.transformRequest and is POST'd as the HTTP request body.
POSTPARAMS
          Data is POST'd to the dataURL, with each property becoming an HTTP parameter, exactly as an HTML form would submit them if it had one input field per property in the data.
POSTXML
          Data is serialized as XML via DataSource.xmlSerialize and POST'd as the HTTP request body with contentType "text/xml".
SOAP
          Data is serialized as XML via DataSource.xmlSerialize, wrapped in a SOAP envelope, and POST'd as the HTTP request body with contentType "text/xml".
 
Method Summary

Enum Constant Detail

GETPARAMS

public static final DSProtocol GETPARAMS
Data is added to the dataURL, with each property in the data becoming an HTTP parameter, eg http://service.com/search?keyword=foo


POSTPARAMS

public static final DSProtocol POSTPARAMS
Data is POST'd to the dataURL, with each property becoming an HTTP parameter, exactly as an HTML form would submit them if it had one input field per property in the data.


POSTXML

public static final DSProtocol POSTXML
Data is serialized as XML via DataSource.xmlSerialize and POST'd as the HTTP request body with contentType "text/xml".


SOAP

public static final DSProtocol SOAP
Data is serialized as XML via DataSource.xmlSerialize, wrapped in a SOAP envelope, and POST'd as the HTTP request body with contentType "text/xml". Generally only used in connection with a WSDL web service.


POSTMESSAGE

public static final DSProtocol POSTMESSAGE
dsRequest.data is assumed to be a String set up by DataSource.transformRequest and is POST'd as the HTTP request body.


CLIENTCUSTOM

public static final DSProtocol CLIENTCUSTOM
This setting entirely bypasses the Smart GWT comm system. Instead of the DataSource sending an HTTP request to a URL, the developer is expected to implement DataSource.transformRequest to perform their own custom logic, and then call DataSource.processResponse to handle the results of this action. This dataProtocol setting can be used to implement access to in-browser resources such as HTML5 "localStorage", native APIs available to applications packaged as native applications, or to implement the DataSource Facade pattern.

Method Detail

values

public static DSProtocol[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
for (DSProtocol c : DSProtocol.values())
    System.out.println(c);

Returns:
an array containing the constants of this enum type, in the order they are declared

valueOf

public static DSProtocol valueOf(java.lang.String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:
name - the name of the enum constant to be returned.
Returns:
the enum constant with the specified name
Throws:
java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
java.lang.NullPointerException - if the argument is null

getValue

public java.lang.String getValue()
Specified by:
getValue in interface ValueEnum
