toUri

public URI toUri()

从接口复制的说明: FileObject

Returns a URI identifying this file object.

指定者:

toUri 在接口中 FileObject

返回:

a URI

getName

public String getName()

从接口复制的说明: FileObject

Gets a user-friendly name for this file object. The exact value returned is not specified but implementations should take care to preserve names as given by the user. For example, if the user writes the filename "BobsApp\Test.java" on the command line, this method should return "BobsApp\Test.java" whereas the toUri method might return file:///C:/Documents%20and%20Settings/UncleBob/BobsApp/Test.java.

指定者:

getName 在接口中 FileObject

返回:

a user-friendly name

openInputStream

public InputStream openInputStream()
                            throws IOException

从接口复制的说明: FileObject

Gets an InputStream for this file object.

指定者:

openInputStream 在接口中 FileObject

返回:

an InputStream

抛出:

IllegalStateException - if this file object was opened for writing and does not support reading

UnsupportedOperationException - if this kind of file object does not support byte access

IOException - if an I/O error occurred

openOutputStream

public OutputStream openOutputStream()
                              throws IOException
