Builder for immutable DomainNameMapping instances.
Type parameters:
  • <V> – concrete type of value objects
Deprecated:Use DomainNameMappingBuilder instead.

Constructor with default initial capacity of the map holding the mappings
Params:

Constructor with initial capacity of the map holding the mappings
Params:
  • initialCapacity – initial capacity for the internal map
  • defaultValue – the default value for DomainNameMapping.map(String) to return when nothing matches the input

Adds a mapping that maps the specified (optionally wildcard) host name to the specified output value. Null values are forbidden for both hostnames and values.

DNS wildcard is supported as hostname. For example, you can use *.netty.io to match netty.io and downloads.netty.io.

Params:
  • hostname – the host name (optionally wildcard)
  • output – the output value that will be returned by DomainNameMapping.map(String) when the specified host name matches the specified input host name

Creates a new instance of immutable DomainNameMapping Attempts to add new mappings to the result object will cause UnsupportedOperationException to be thrown
Returns:new DomainNameMapping instance
