Constructor

Parameters:

client - the (valid) DropBox client to use

Method Detail

getTotalSpace

public long getTotalSpace()
                   throws IOException

Returns the size, in bytes, of the file store.

Specified by:

getTotalSpace in class FileStore

Returns:

the size of the file store, in bytes

Throws:

IOException - if an I/O error occurs

getUsableSpace

public long getUsableSpace()
                    throws IOException

Returns the number of bytes available to this Java virtual machine on the file store.

The returned number of available bytes is a hint, but not a guarantee, that it is possible to use most or any of these bytes. The number of usable bytes is most likely to be accurate immediately after the space attributes are obtained. It is likely to be made inaccurate by any external I/O operations including those made on the system outside of this Java virtual machine.

Specified by:

getUsableSpace in class FileStore

Returns:

the number of bytes available

Throws:

IOException - if an I/O error occurs

getUnallocatedSpace

public long getUnallocatedSpace()
                         throws IOException

Returns the number of unallocated bytes in the file store.

The returned number of unallocated bytes is a hint, but not a guarantee, that it is possible to use most or any of these bytes. The number of unallocated bytes is most likely to be accurate immediately after the space attributes are obtained. It is likely to be made inaccurate by any external I/O operations including those made on the system outside of this virtual machine.

Specified by:

getUnallocatedSpace in class FileStore

Returns:

the number of unallocated bytes

Throws:

IOException - if an I/O error occurs

supportsFileAttributeView

public boolean supportsFileAttributeView(Class<? extends FileAttributeView> type)

Tells whether or not this file store supports the file attributes identified by the given file attribute view.

Invoking this method to test if the file store supports BasicFileAttributeView will always return true. In the case of the default provider, this method cannot guarantee to give the correct result when the file store is not a local storage device. The reasons for this are implementation specific and therefore unspecified.

Specified by:

supportsFileAttributeView in class FileStore

Parameters:

type - the file attribute view type

Returns:

true if, and only if, the file attribute view is supported

supportsFileAttributeView

public boolean supportsFileAttributeView(String name)

Tells whether or not this file store supports the file attributes identified by the given file attribute view.

Invoking this method to test if the file store supports BasicFileAttributeView, identified by the name "basic" will always return true. In the case of the default provider, this method cannot guarantee to give the correct result when the file store is not a local storage device. The reasons for this are implementation specific and therefore unspecified.

Specified by:

supportsFileAttributeView in class FileStore

Parameters:

name - the name of file attribute view

Returns:

true if, and only if, the file attribute view is supported
