override def hashCode(): Int

Calculate a hash code value for the object.

Calculate a hash code value for the object.

The default hashing algorithm is platform dependent.

Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

Attributes

Returns:

the hash code value for this object.

Attributes

Source:
Message.scala

Representation of the query string as a map

Representation of the query string as a map

In case a parameter is available in query string but no value is there the sequence will be empty. If the value is empty the the sequence contains an empty string.

=====Examples=====

Query StringMap
?param=vMap("param" -> Seq("v"))
?param=Map("param" -> Seq(""))
?paramMap("param" -> Seq())
?=valueMap("" -> Seq("value"))
?p1=v1&p1=v2&p2=v3&p2=v4Map("p1" -> Seq("v1","v2"), "p2" -> Seq("v3","v4"))

The query string is lazily parsed. If an error occurs during parsing an empty Map is returned.
