  - resolve
```
public URI resolve(URI base,
                   boolean preserveRootParents)
```
    Description copied from class: URI
    
    Resolves this URI reference against a base absolute hierarchical URI, returning the resulting absolute URI. If already absolute, the URI itself is returned. URI resolution is described in detail in section 5.2 of RFC 2396, "Resolving Relative References to Absolute Form."
    During resolution, empty segments, self references ("."), and parent references ("..") are interpreted, so that they can be removed from the path. Step 6(g) gives a choice of how to handle the case where parent references point to a path above the root: the offending segments can be preserved or discarded. This method can do either.
    
    Overrides:
    
    resolve in class URI
    
    preserveRootParents - true if segments referring to the parent of the root path are to be preserved; false if they are to be discarded.
  - deresolve

                     boolean anyRelPath,
                     boolean shorterRelPath)
```
    Description copied from class: URI
    
    Finds an absolute URI that, when resolved against the given base absolute hierarchical URI using resolve, will yield this absolute URI. If base is non-hierarchical or is relative, or this is non-hierarchical or is relative, this will be returned.
    
    Overrides:
    
    deresolve in class URI
    
    preserveRootParents - the boolean argument to resolve(URI, boolean) for which the returned URI should resolve to this URI.
    
    anyRelPath - if true, the returned URI's path (if any) will be relative, if possible. If false, the form of the result's path will depend upon the next parameter.
    
    shorterRelPath - if anyRelPath is false and this parameter is true, the returned URI's path (if any) will be relative, if one can be found that is no longer (by number of segments) than the absolute path. If both anyRelPath and this parameter are false, it will be absolute.

    Description copied from class: URI
    If this URI may refer directly to a locally accessible file, as determined by isFile, decodes and formats the URI as a pathname to that file; returns null otherwise.
    If there is no authority, the format of this string is:
```
   device/pathSegment1/pathSegment2...
```
    If there is an authority, it is:
```
   //authority/device/pathSegment1/pathSegment2...
```
    However, the character used as a separator is system-dependent and obtained from File.separatorChar.
    Overrides:
    
    toFileString in class URI
  - toPlatformString
```
public java.lang.String toPlatformString(boolean decode)
```
    Description copied from class: URI
    
    If this is a platform URI, as determined by URI.isPlatform(), returns the workspace-relative or plug-in-based path to the resource, optionally decoding the segments in the process.
    
    Overrides:
    
    toPlatformString in class URI

  - appendSegment
```
public URI appendSegment(java.lang.String segment)
```
    Description copied from class: URI
    
    Returns the URI formed by appending the specified segment on to the end of the path of this URI, if hierarchical; this URI unchanged, otherwise. If this URI has an authority and/or device, but no path, the segment becomes the first under the root in an absolute path.
    
    Overrides:
    
    appendSegment in class URI
  - appendSegments
```
public URI appendSegments(java.lang.String[] segments)
```
    Description copied from class: URI
    
    Returns the URI formed by appending the specified segments on to the end of the path of this URI, if hierarchical; this URI unchanged, otherwise. If this URI has an authority and/or device, but no path, the segments are made to form an absolute path.
    
    Overrides:
    
    appendSegments in class URI
    
    Parameters:
    
    segments - an array of non-null strings, each representing one segment of the path. If desired, a trailing separator should be represented by an empty-string segment as the last element of the array.
  - trimSegments
```
public URI trimSegments(int i)
```
    Description copied from class: URI
    
    Returns the URI formed by trimming the specified number of segments (including empty segments, such as one representing a trailing separator) from the end of the path of this URI, if hierarchical; otherwise, this URI is returned unchanged.
    Note that if all segments are trimmed from an absolute path, the root absolute path remains.
    
    Overrides:
    
    trimSegments in class URI
    
    Parameters:
    
    i - the number of segments to be trimmed in the returned URI. If less than 1, this URI is returned unchanged; if equal to or greater than the number of segments in this URI's path, all segments are trimmed.
  - hasTrailingPathSeparator
```
public boolean hasTrailingPathSeparator()
```
    Description copied from class: URI
    
    Returns true if this is a hierarchical URI that has a path that ends with a trailing separator; false otherwise.
    A trailing separator is represented as an empty segment as the last segment in the path; note that this definition does not include the lone separator in the root absolute path.
    
    Overrides:
    
    hasTrailingPathSeparator in class URI
  - fileExtension
```
public java.lang.String fileExtension()
```
    Description copied from class: URI
    
    If this is a hierarchical URI whose path includes a file extension, that file extension is returned; null otherwise. We define a file extension as any string following the last period (".") in the final path segment. If there is no path, the path ends in a trailing separator, or the final segment contains no period, then we consider there to be no file extension. If the final segment ends in a period, then the file extension is an empty string.
    
    Overrides:
    
    fileExtension in class URI
  - appendFileExtension
```
public URI appendFileExtension(java.lang.String fileExtension)
```
    Description copied from class: URI
    
    Returns the URI formed by appending a period (".") followed by the specified file extension to the last path segment of this URI, if it is hierarchical with a non-empty path ending in a non-empty segment; otherwise, this URI is returned unchanged.
    The extension is appended regardless of whether the segment already contains an extension.
    
    Overrides:
    
    appendFileExtension in class URI
  - trimFileExtension
```
public URI trimFileExtension()
```
    Description copied from class: URI
    
    If this URI has a non-null fileExtension, returns the URI formed by removing it; this URI unchanged, otherwise.
    
    Overrides:
    
    trimFileExtension in class URI
  - replacePrefix
```
public URI replacePrefix(URI oldPrefix,
                         URI newPrefix)
```
    Description copied from class: URI
    
    If this is a hierarchical URI reference and oldPrefix is a prefix of it, this returns the URI formed by replacing it by newPrefix; null otherwise.
    In order to be a prefix, the oldPrefix's isPrefix must return true, and it must match this URI's scheme, authority, and device. Also, the paths must match, up to prefix's end.
    
    Overrides:
    
    replacePrefix in class URI
