Constructor Detail

### POIFSDocumentPath

    public POIFSDocumentPath(java.lang.String[] components)
                      throws java.lang.IllegalArgumentException

  constructor for the path of a document that is not in the root of the POIFSFileSystem

Parameters:
  `components` - the Strings making up the path to a document. The Strings must be ordered as they appear in the directory hierarchy of the the document -- the first string must be the name of a directory in the root of the POIFSFileSystem, and every Nth (for N > 1) string thereafter must be the name of a directory in the directory identified by the (N-1)th string.

  If the components parameter is null or has zero length, the POIFSDocumentPath is appropriate for a document that is in the root of a POIFSFileSystem

Throws:
  `java.lang.IllegalArgumentException` - if any of the elements in the components parameter are null or have zero length

### POIFSDocumentPath

    public POIFSDocumentPath()

  simple constructor for the path of a document that is in the root of the POIFSFileSystem. The constructor that takes an array of Strings can also be used to create such a POIFSDocumentPath by passing it a null or empty String array

### POIFSDocumentPath

    public POIFSDocumentPath(POIFSDocumentPath path,
                             java.lang.String[] components)
                      throws java.lang.IllegalArgumentException

  constructor that adds additional subdirectories to an existing path

Parameters:
  `path` - the existing path
  `components` - the additional subdirectory names to be added
Throws:
  `java.lang.IllegalArgumentException` - if any of the Strings in components is null or zero length

Method Detail

### equals

    public boolean equals(java.lang.Object o)

  equality. Two POIFSDocumentPath instances are equal if they have the same number of component Strings, and if each component String is equal to its coresponding component String

  Parameters:
    `o` - the object we're checking equality for
  Returns:
    true if the object is equal to this object

### hashCode

    public int hashCode()

  calculate and return the hashcode

  Returns:
    hashcode

### length

    public int length()

  Returns:
    the number of components

### getComponent

    public java.lang.String getComponent(int n)
                                  throws java.lang.ArrayIndexOutOfBoundsException

  get the specified component

  Parameters:
    `n` - which component (0 ... length() - 1)
  Returns:
    the nth component;
  Throws:
    `java.lang.ArrayIndexOutOfBoundsException` - if n < 0 or n >= length()

### getParent

    public POIFSDocumentPath getParent()

  Returns the path's parent or `null` if this path is the root path.

  Returns:
    path of parent, or null if this path is the root path

### toString

    public java.lang.String toString()

  Returns a string representation of the path. Components are separated by the platform-specific file separator.

  Returns:
    string representation
