- DomainNameMappingBuilder<V>
private static final class DomainNameMappingBuilder.ImmutableDomainNameMapping<V> extends DomainNameMapping<V>
Immutable mapping from domain name pattern to its associated value object. Mapping is represented by two arrays: keys and values. Key domainNamePatterns[i] is associated with values[i].

add
@Deprecated public DomainNameMapping<V> add(java.lang.String hostname, V output)
Deprecated.Description copied from class:DomainNameMapping
Adds a mapping that maps the specified (optionally wildcard) host name to the specified output value.DNS wildcard is supported as hostname. For example, you can use
*.netty.io
to matchnetty.io
anddownloads.netty.io
.- Overrides:
add
in classDomainNameMapping<V>
- Parameters:
hostname
- the host name (optionally wildcard)output
- the output value that will be returned byDomainNameMapping.map(String)
when the specified host name matches the specified input host name
-
map
public V map(java.lang.String hostname)
Description copied from interface:Mapping
Returns mapped value of the specified input.
-
asMap
public java.util.Map<java.lang.String,V> asMap()
Description copied from class:DomainNameMapping
Returns a read-onlyMap
of the domain mapping patterns and their associated value objects.- Overrides:
asMap
in classDomainNameMapping<V>
-
toString
public java.lang.String toString()
- Overrides:
toString
in classDomainNameMapping<V>
-
estimateBufferSize
private static int estimateBufferSize(int defaultValueLength, int numberOfMappings, int estimatedMappingLength)
Estimates the length of string representation of the given instance: est = lengthOfConstantComponents + defaultValueLength + (estimatedMappingLength * numOfMappings) * 1.10- Parameters:
defaultValueLength
- length of string representation ofDomainNameMappingBuilder.defaultValue
numberOfMappings
- number of mappings the given instance holds, e.g. {@link #domainNamePatterns#length}estimatedMappingLength
- estimated size taken by one mapping- Returns:
- estimated length of string returned by
toString()
-
