getParameter

String getParameter(String paramName)

Return the request parameter of the given name, or null if none.

Retrieves the first parameter value in case of a multi-value parameter.

See Also:: ServletRequest.getParameter(String)

getParameterValues

String[] getParameterValues(String paramName)

Return the request parameter values for the given parameter name, or null if none.

A single-value parameter will be exposed as an array with a single element.

See Also:: ServletRequest.getParameterValues(String)

getParameterMap

Map getParameterMap()

Return a immutable Map of the request parameters, with parameter names as map keys and parameter values as map values. The map values will be of type String array.

A single-value parameter will be exposed as an array with a single element.
