Overrides:

canRead in class AbstractFile

Returns:

true if and only if the file exists and can be read by the application; false otherwise

exists

public boolean exists()

Description copied from interface: FileIf

Tests whether the file or directory exists.

Specified by:

exists in interface FileIf

Overrides:

exists in class AbstractFile

Returns:

true if and only if this file or directory exists; false otherwise

getInputStream

public java.io.InputStream getInputStream()
                                   throws java.io.IOException

Returns the path of the parent of the file. This is just the last name in the pathname's name sequence.

Returns:

a String specifying the path of the file's parent

getParentFile

public FileIf getParentFile()

Description copied from interface: FileIf

Returns the parent of the file.

Returns:

the FileIf interface of this file's parent

getPath

public java.lang.String getPath()
