java.lang.Object
   org.apache.tomcat.util.net.URL

URL
final public class URL implements Serializable(Code)

URL is designed to provide public APIs for parsing and synthesizing Uniform Resource Locators as similar as possible to the APIs of java.net.URL, but without the ability to open a stream or connection. One of the consequences of this is that you can construct URLs for protocols for which a URLStreamHandler is not available (such as an "https" URL when JSSE is not installed).

WARNING - This class assumes that the string representation of a URL conforms to the spec argument as described in RFC 2396 "Uniform Resource Identifiers: Generic Syntax":

 <scheme>//<authority><path>?<query>#<fragment>
 

FIXME - This class really ought to end up in a Commons package someplace.

Constructor Detail
URL
public URL(String spec) throws MalformedURLException(Code)
Create a URL object from the specified String representation.
Parameters:
  spec - String representation of the URL
exception:
  MalformedURLException - if the string representationcannot be parsed successfully



URL
public URL(URL context, String spec) throws MalformedURLException(Code)
Create a URL object by parsing a string representation relative to a specified context. Based on logic from JDK 1.3.1's java.net.URL.
Parameters:
  context - URL against which the relative representationis resolved
Parameters:
  spec - String representation of the URL (usually relative)
exception:
  MalformedURLException - if the string representationcannot be parsed successfully



URL
public URL(String protocol, String host, String file) throws MalformedURLException(Code)
Create a URL object from the specified components. The default port number for the specified protocol will be used.
Parameters:
  protocol - Name of the protocol to use
Parameters:
  host - Name of the host addressed by this protocol
Parameters:
  file - Filename on the specified host
exception:
  MalformedURLException - is never thrown, but present forcompatible APIs



URL
public URL(String protocol, String host, int port, String file) throws MalformedURLException(Code)
Create a URL object from the specified components. Specifying a port number of -1 indicates that the URL should use the default port for that protocol. Based on logic from JDK 1.3.1's java.net.URL.
Parameters:
  protocol - Name of the protocol to use
Parameters:
  host - Name of the host addressed by this protocol
Parameters:
  port - Port number, or -1 for the default port for this protocol
Parameters:
  file - Filename on the specified host
exception:
  MalformedURLException - is never thrown, but present forcompatible APIs




Method Detail
equals
public boolean equals(Object obj)(Code)
Compare two URLs for equality. The result is true if and only if the argument is not null, and is a URL object that represents the same URL as this object. Two URLs are equal if they have the same protocol and reference the same host, the same port number on the host, and the same file and anchor on the host.
Parameters:
  obj - The URL to compare against



getAuthority
public String getAuthority()(Code)
Return the authority part of the URL.



getFile
public String getFile()(Code)
Return the filename part of the URL. NOTE - For compatibility with java.net.URL, this value includes the query string if there was one. For just the path portion, call getPath() instead.



getHost
public String getHost()(Code)
Return the host name part of the URL.



getPath
public String getPath()(Code)
Return the path part of the URL.



getPort
public int getPort()(Code)
Return the port number part of the URL.



getProtocol
public String getProtocol()(Code)
Return the protocol name part of the URL.



getQuery
public String getQuery()(Code)
Return the query part of the URL.



getRef
public String getRef()(Code)
Return the reference part of the URL.



getUserInfo
public String getUserInfo()(Code)
Return the user info part of the URL.



normalize
public void normalize() throws MalformedURLException(Code)
Normalize the path (and therefore file) portions of this URL.

NOTE - This method is not part of the public API of java.net.URL, but is provided as a value added service of this implementation.
exception:
  MalformedURLException - if a normalization error occurs,such as trying to move about the hierarchical root




sameFile
public boolean sameFile(URL other)(Code)
Compare two URLs, excluding the "ref" fields. Returns true if this URL and the other argument both refer to the same resource. The two URLs might not both contain the same anchor.



toExternalForm
public String toExternalForm()(Code)
Return a string representation of this URL. This follow the rules in RFC 2396, Section 5.2, Step 7.



toString
public String toString()(Code)
Return a string representation of this object.
