All Implemented Interfaces:

Serializable, Cloneable, Comparable<URI>
```
public class URI
extends Object
implements Cloneable, Serializable, Comparable<URI>
```
An URI. This is a pure (immutable) value object.

This does more normalization of hierarchical URIs (URLs) than described in the RFC and allows hosts with underscores.

```
public URI(String uriString)
```
    Creates an URI without keeping the fragment (the part starting by #). If the uri is hierarchical, it is normalized and incorrect hierarchical uris which looks like urls are attempted repaired.
    
    Relative uris are not supported.
    
    Parameters:
    
    uriString - the uri string
    
    Throws:
    
    NullPointerException - if the given uriString is null
  - URI
```
public URI(String uriString,
           boolean keepFragment)
```
    Creates an URI, optionaly keeping the fragment (the part starting by #). If the uri is hierarchical, it is normalized and incorrect hierarchical uris which looks like urls are attempted repaired.
    Relative uris are not supported.
    
    Parameters:
    
    uriString - the uri string
    
    keepFragment - true to keep the fragment
    
    Throws:
    
    NullPointerException - if the given uriString is null
  - URI
```
public URI(String uriString,
           boolean keepFragment,
           boolean hierarchicalOnly)
```
    Creates an URI, optionaly keeping the fragment (the part starting by #). If the uri is hierarchical, it is normalized and incorrect hierarchical uris which looks like urls are attempted repaired.
    Relative uris are not supported.
    
    Parameters:
    
    uriString - the uri string
    
    keepFragment - true to keep the fragment
    
    hierarchicalOnly - will force any uri string given to be parsed as a hierarchical one, causing the uri to be invalid if it isn't
    
    Throws:
    
    NullPointerException - if the given uriString is null
  - URI
```
public URI(String scheme,
           String host,
           int port,
           String rest)
```
    Creates an url type uri
- Method Detail
  - isValid
```
public boolean isValid()
```
    Returns whether this is a valid URI (after normalizing). All non-hierarchical uri's containing a scheme is valid.
  - getScheme
```
public String getScheme()
```
    Returns the normalized scheme of this URI.
    
    Returns:
    
    the normalized scheme (protocol), or null if there is none, which may only be the case with non-hierarchical URIs
  - isOpaque
```
public boolean isOpaque()
```
    Returns whether this URI is hierarchical or opaque. A typical example of an hierarchical URI is an URL, while URI's are mailto, news and such.
    
    Returns:
    
    true if the url is opaque, false if it is hierarchical
  - getHost
```
public String getHost()
```
    Returns the normalized host of this URI.
    
    Returns:
    
    the normalized host, or null if there is none, which may only be the case if this is a non-hierarchical uri
  - getPort
```
public int getPort()
```
    Returns the port number of this scheme if set explicitly, or -1 otherwise
  - getRest
```
public String getRest()
```
    Returns the rest of this uri, that is what is following the host or port. This is path, query and fragment as defined in RFC 2396. Returns an empty string if this uri has no rest.
  - getDomain
```
public String getDomain()
```
  - getMainTld
```
public String getMainTld()
```
  - getPath
```
public String getPath()
```
  - getFilename
```
public String getFilename()
```
  - getExtension
```
public String getExtension()
```
  - getQuery
```
public String getQuery()
```
  - getFragment
```
public String getFragment()
```
  - getParams
```
public String getParams()
```
  - tokenize
```
public static String[] tokenize(String item)
```
  - tokenize
```
public List<URI.Token> tokenize()
```
  - getInvalidExplanation
```
public String getInvalidExplanation()
```
    Returns an explanation of why this uri is invalid, or null if it is valid
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - equals
```
public boolean equals(Object object)
```
    Overrides:
    
    equals in class Object
  - compareTo
```
public int compareTo(URI object)
```
    Specified by:
    
    compareTo in interface Comparable<URI>
  - clone
```
public Object clone()
```
    Overrides:
    
    clone in class Object
  - setScheme
```
public URI setScheme(String scheme)
```
    Returns a new URI with a changed scheme
  - setHost
```
public URI setHost(String host)
```
    Returns a new URI with a changed host (or authority)
  - setPort
```
public URI setPort(int port)
```
    Returns a new URI with a changed port
  - setRest
```
public URI setRest(String rest)
```
    Returns a new URI with a changed rest
  - addParameter
```
public URI addParameter(String name,
                        String value)
```
    Returns a new uri with the an additional parameter
  - stringValue
```
public String stringValue()
```
    Returns this uri as a string
  - toString
```
public String toString()
```
    Returns this URI as a string
    
    Overrides:
    
    toString in class Object
  - getDepth
```
public int getDepth()
```
    Returns the depth of this uri. The depth of an hierarchical uri equals the number of slashes which are not separating the protocol and the host, and not at the end.
    
    Returns:
    
    the depth of this uri if it is hierarchical, or 0 if it is opaque
