the structure

Constructor Detail

Path

protected Path()

default constructor, only used internally

Path

public Path(java.lang.String path)

uses the given dot-path

Parameters:

path - path in dot-notation

Path

public Path(java.util.Vector<PropertyPath.PathElement> elements)

uses the vector with PathElement objects to initialize with

Parameters:

elements - the PathElements to use

Path

public Path(java.lang.String[] elements)

uses the given array as elements for the path

Parameters:

elements - the path elements to use

Method Detail

breakUp

protected java.util.Vector<PropertyPath.PathElement> breakUp(java.lang.String path)

breaks up the given path and returns it as vector

Parameters:

path - the path to break up

Returns:

the single elements of the path

get

public PropertyPath.PathElement get(int index)

returns the element at the given index

Parameters:

index - the index of the element to return

Returns:

the specified element

size

public int size()

returns the number of path elements of this structure

Returns:

the number of path elements

parsePath

public static PropertyPath.Path parsePath(java.lang.String path)

returns a path object based on the given path string

Parameters:

path - path to work on

Returns:

the path structure

subpath

public PropertyPath.Path subpath(int startIndex)

returns a subpath of the current structure, starting with the specified element index up to the end

Parameters:

startIndex - the first element of the subpath

Returns:

the new subpath

subpath

public PropertyPath.Path subpath(int startIndex,
                                 int endIndex)

returns a subpath of the current structure, starting with the specified element index up. The endIndex specifies the element that is not part of the new subpath. In other words, the new path contains the elements from "startIndex" up to "(endIndex-1)".

Parameters:

startIndex - the first element of the subpath

endIndex - the element that is after the last added element

Returns:

the new subpath

toString

public java.lang.String toString()

returns the structure again as a dot-path

Overrides:

toString in class java.lang.Object

Returns:

the path structure as dot-path

getRevision

public java.lang.String getRevision()

Returns the revision string.

Specified by:

getRevision in interface RevisionHandler

Returns:

the revision
