Class POIFSDocumentPath

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

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

Overrides:

equals in class java.lang.Object

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

Overrides:

hashCode in class java.lang.Object

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

getName

public java.lang.String getName()

Returns the last name in the document path's name sequence. If the document path's name sequence is empty, then the empty string is returned.

Returns:

The last name in the document path's name sequence, or empty string if this 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 File.separatorChar

Overrides:

toString in class java.lang.Object

Returns:

string representation
