Method Detail

getLocale

public Locale getLocale()

Returns the current locale derived from the locale detection mechanism.

Specified by:

getLocale in interface ServletRequest

Overrides:

getLocale in class ServletRequestWrapper

Returns:

Locale object

getLocales

public Enumeration getLocales()

Returns the Enumeration object that includes the current locales derived from the locale detection mechanism.

Specified by:

getLocales in interface ServletRequest

Overrides:

getLocales in class ServletRequestWrapper

Enumeration object

getCharacterEncoding

public String getCharacterEncoding()

Returns the name of the character encoding used in the body of this request, or returns null if the request does not specify character encoding.

Specified by:

getCharacterEncoding in interface ServletRequest

Overrides:

getCharacterEncoding in class ServletRequestWrapper

Returns:

a String containing the name of the character encoding, or returns null if the request does not specify character encoding

getRawParameter

public String getRawParameter(String key)

Returns the raw value of the parameter corresponding to the key. This method does not perform character set conversion on the returned parameter.

Parameters:

key - the key string

Returns:

a String value corresponding to the key

getParameter

public String getParameter(String key)

Returns the parameter value corresponding to the key.

Specified by:

getParameter in interface ServletRequest

Overrides:

getParameter in class ServletRequestWrapper

Parameters:

key - the key string

Returns:

a String value corresponding to the key

getParameterValues

public String[] getParameterValues(String key)

Returns an array of String objects containing all the values of the given request parameter, or returns null if the parameter does not exist.

Specified by:

getParameterValues in interface ServletRequest

Overrides:

getParameterValues in class ServletRequestWrapper

Parameters:

key - a parameter name

Returns:

an array of String objects containing the parameter values corresponding to the key

getParameterMap

public Map getParameterMap()

Returns a java.util.Map object of the parameters of this request. For HTTP servlets, parameters are contained in the query string or posted form data.

Specified by:

getParameterMap in interface ServletRequest

Overrides:

getParameterMap in class ServletRequestWrapper

Returns:

a java.util.Map object containing parameter names as keys and parameter values as map values

getParameterNames

public Enumeration getParameterNames()

Returns an Enumeration of String objects containing the names of the parameters in this request. If the request has no parameters, the method returns an empty Enumeration object.

Specified by:

getParameterNames in interface ServletRequest

Overrides:

a java.util.Enumeration object containing parameter names

setCharacterEncoding

public void setCharacterEncoding(String env)
                          throws UnsupportedEncodingException

Sets the character set of the input stream. By default, GDK determines the input character set based on the application configuration file. Use this method only if it is necessary to explicitly specify the character set.

Specified by:

Parameters:

env - an IANA character set name
