Constructor Details

HostsTxtNamingService

public HostsTxtNamingService(I2PAppContext context)

The naming service should only be constructed and accessed through the application context. This constructor should only be used by the appropriate application context itself.

Method Details

lookup

public Destination lookup(String hostname,
 Properties lookupOptions,
 Properties storedOptions)

Description copied from class: NamingService

Same as lookup(hostname) but with in and out options Note that whether this (and lookup(hostname)) resolve Base 32 addresses in the form {52 chars}.b32.i2p is NamingService-specific.

Overrides:

lookup in class MetaNamingService

Parameters:

hostname - mixed case as it could be a key

lookupOptions - input parameter, NamingService-specific, can be null

storedOptions - output parameter, NamingService-specific, any stored properties will be added if non-null

Returns:

dest or null

put

public boolean put(String hostname,
 Destination d,
 Properties options)

Description copied from class: MetaNamingService

Stores in the last service

Overrides:

put in class MetaNamingService

Parameters:

options - NamingService-specific, can be null

Returns:

success

putIfAbsent

public boolean putIfAbsent(String hostname,
 Destination d,
 Properties options)

Description copied from class: MetaNamingService

Stores in the last service

Overrides:

putIfAbsent in class MetaNamingService

Parameters:

options - NamingService-specific, can be null

Returns:

success

remove

public boolean remove(String hostname,
 Properties options)

Description copied from class: MetaNamingService

Removes from all services

Overrides:

remove in class MetaNamingService

Parameters:

options - NamingService-specific, can be null

Returns:

true if removed successfully, false on error or if it did not exist

getNames

public Set<String> getNames(Properties options)

All services aggregated, unless options contains the property "file", in which case only for that file

Overrides:

getNames in class MetaNamingService

Parameters:

options - NamingService-specific, can be null

Returns:

all known hostnames (matching the options if non-null) or empty Set if none; Returned Set is not necessarily sorted, implementation dependent
