getRequestParameter

public RequestParameter getRequestParameter(java.lang.String name)

Description copied from interface: SlingHttpServletRequest

Returns the value of a request parameter as a RequestParameter, or null if the parameter does not exist.

This method should only be used if the parameter has only one value. If the parameter might have more than one value, use SlingHttpServletRequest.getRequestParameters(String).

If this method is used with a multivalued parameter, the value returned is equal to the first value in the array returned by getRequestParameters.

This method is a shortcut for getRequestParameterMap().getValue(String).

Specified by:

getRequestParameter in interface SlingHttpServletRequest

Parameters:

name - a String specifying the name of the parameter

Returns:

a RequestParameter representing the single value of the parameter

See Also:

SlingHttpServletRequest.getRequestParameters(String), RequestParameterMap.getValue(String)

getRequestParameterMap

public RequestParameterMap getRequestParameterMap()

Description copied from interface: SlingHttpServletRequest

Returns a Map of the parameters of this request.

The values in the returned Map are from type RequestParameter array (RequestParameter[]).

If no parameters exist this method returns an empty Map.

Specified by:

getRequestParameterMap in interface SlingHttpServletRequest

Returns:

an immutable Map containing parameter names as keys and parameter values as map values, or an empty Map if no parameters exist. The keys in the parameter map are of type String. The values in the parameter map are of type RequestParameter array (RequestParameter[]).

getRequestParameterList

public java.util.List<RequestParameter> getRequestParameterList()

Description copied from interface: SlingHttpServletRequest

Returns the request parameters as instances of the RequestParameter interface in the order or the request where the query string parameters are first and the POST request parameters are second.

Specified by:

getRequestParameterList in interface SlingHttpServletRequest

If the parameter has a single value, the array has a length of 1.

This method is a shortcut for getRequestParameterMap().getValues(String).

Specified by:

getRequestParameters in interface SlingHttpServletRequest

Parameters:

name - a String containing the name of the parameter the value of which is requested

Returns:

an array of RequestParameter objects containing the parameter values.

See Also:

SlingHttpServletRequest.getRequestParameter(String), RequestParameterMap.getValues(String)
