Constructor Detail

SynchronizedByteProvider

public SynchronizedByteProvider(ByteProvider provider)

Constructs a SynchronizedByteProvider around the specified ByteProvider

Parameters:

provider - the ByteProvider to make thread-safe

Method Detail

getFSRL

public FSRL getFSRL()

Description copied from interface: ByteProvider

Returns the FSRL of the underlying file for this byte provider, or null if this byte provider is not associated with a file.

Specified by:

getFSRL in interface ByteProvider

Returns:

The FSRL of the underlying File, or null if no associated File.

getFile

public java.io.File getFile()

Description copied from interface: ByteProvider

Returns the underlying File for this ByteProvider, or null if this ByteProvider is not associated with a File.

Specified by:

getFile in interface ByteProvider

Returns:

the underlying file for this byte provider

getName

public java.lang.String getName()

Description copied from interface: ByteProvider

Returns the name of the ByteProvider. For example, the underlying file name.

Specified by:

getName in interface ByteProvider

Returns:

the name of the ByteProvider or null if there is no name

getAbsolutePath

public java.lang.String getAbsolutePath()

Description copied from interface: ByteProvider

Returns the absolute path (similar to, but not a, URI) to the ByteProvider. For example, the complete path to the file.

Specified by:

getAbsolutePath in interface ByteProvider

Returns:

the absolute path to the ByteProvider or null if not associated with a File.

length

public long length()
            throws java.io.IOException

Description copied from interface: ByteProvider

Returns the length of the ByteProvider

Specified by:

length in interface ByteProvider

Returns:

the length of the ByteProvider

Throws:

java.io.IOException - if an I/O error occurs

isValidIndex

public boolean isValidIndex(long index)

Description copied from interface: ByteProvider

Returns true if the specified index is valid.

Specified by:

isValidIndex in interface ByteProvider

Parameters:

index - the index in the byte provider to check

Returns:

true if the specified index is valid

close

public void close()
           throws java.io.IOException

Description copied from interface: ByteProvider

Releases any resources the ByteProvider may have occupied

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface ByteProvider

Specified by:

close in interface java.io.Closeable

Throws:

java.io.IOException - if an I/O error occurs

readByte

public byte readByte(long index)
              throws java.io.IOException

Description copied from interface: ByteProvider

Reads a byte at the specified index

Specified by:

readByte in interface ByteProvider

Parameters:

index - the index of the byte to read

Returns:

the byte read from the specified index

Throws:

java.io.IOException - if an I/O error occurs

readBytes

public byte[] readBytes(long index,
                        long length)

Reads a byte array at the specified index

Specified by:

readBytes in interface ByteProvider

Parameters:

index - the index of the byte to read

length - the number of bytes to read

Returns:

the byte array read from the specified index

Throws:

java.io.IOException - if an I/O error occurs

getInputStream

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

Description copied from interface: ByteProvider

Returns an input stream to the underlying byte provider starting at the specified index.

The caller is responsible for closing the returned InputStream instance.

If you need to override this default implementation, please document why your inputstream is needed.

Specified by:

getInputStream in interface ByteProvider

Parameters:

index - where in the ByteProvider to start the InputStream
