Method Detail

getParameter

public java.lang.String getParameter(java.lang.String name)

Returns the value of the named parameter, or null if it is not set. A zero-length String indicates flag parameter.

Throws:

java.text.ParseException - which signals that an error has been reached unexpectedly while parsing the parameter name or value.

getParameterNames

public java.util.Iterator getParameterNames()

Returns an Iterator over the names (Strings) of all parameters present in this ParametersHeader.

Returns:

an Iterator over all the parameter names
