Methods
Name | Description |
---|---|
getHostByAddr
(addr)
|
Resolve IPv4 address number. |
getHostByAddr
(addr)
|
Same as previous, but addr is an IPv4 address string in the dotted-decimal form a.b.c.d. |
getHostByName
(name)
|
Resolve host name. |
factory
(classname)
|
Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor. |
opCmp
(o)
|
Compare with another Object obj. |
opEquals
(o)
|
Test whether this is equal to o .
The default implementation only compares by identity (using the is operator).
Generally, overrides for opEquals should attempt to compare objects by their contents.
|
toHash
()
|
Compute hash function for Object. |
toString
()
|
Convert Object to a human readable string. |
Example
InternetHost ih = new InternetHost;
ih .getHostByAddr(0x7F_00_00_01);
writeln(ih .addrList[0]); // 0x7F_00_00_01
ih .getHostByAddr("127.0.0.1");
writeln(ih .addrList[0]); // 0x7F_00_00_01
if (!ih .getHostByName("www.digitalmars.com"))
return; // don't fail if not connected to internet
assert(ih .addrList .length);
InternetAddress ia = new InternetAddress(ih .addrList[0], InternetAddress .PORT_ANY);
assert(ih .name == "www.digitalmars.com" || ih .name == "digitalmars.com",
ih .name);
assert(ih .getHostByAddr(ih .addrList[0]));
string getHostNameFromInt = ih .name .dup;
assert(ih .getHostByAddr(ia .toAddrString()));
string getHostNameFromStr = ih .name .dup;
writeln(getHostNameFromInt); // getHostNameFromStr
