ParameterDirectives

When to use which parameter directive?

Usually, you want to use the high-level parameters directive. When you need more low-level access you can use the table below to decide which directive to use which shows properties of different parameter directives.

directive	level	ordering	multi
parameter	high	no	no
parameters	high	no	yes
parameterMap	low	no	no
parameterMultiMap	low	no	yes
parameterSeqparameterList	low	yes	yes

level

high-level parameter directives extract subset of all parameters by name and allow conversions and automatically report errors if expectations are not met, low-level directives give you all parameters at once, leaving all further processing to you

ordering

original ordering from request URL is preserved

multi

multiple values per parameter name are possible
