Constructor Detail

FileImageOutputStreamExtImpl

public FileImageOutputStreamExtImpl(File file)
                             throws FileNotFoundException,
                                    IOException

A constructor which accepts a File as input.

Parameters:

eraf -

Throws:

FileNotFoundException

IOException

FileImageOutputStreamExtImpl

public FileImageOutputStreamExtImpl(File file,
                                    int bufSize)
                             throws FileNotFoundException,
                                    IOException

A constructor which accepts a File as input.

Parameters:

eraf -

bufSize -

Throws:

FileNotFoundException

IOException

Method Detail

read

public int read()
         throws IOException

Specified by:

read in interface ImageInputStream

Specified by:

read in class ImageInputStreamImpl

Throws:

IOException

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException

Specified by:

read in interface ImageInputStream

Specified by:

read in class ImageInputStreamImpl

Throws:

IOException

write

public void write(int b)
           throws IOException

Specified by:

write in interface DataOutput

Specified by:

write in interface ImageOutputStream

Specified by:

write in class ImageOutputStreamImpl

Throws:

IOException

write

public void write(byte[] b,
                  int off,
                  int len)
           throws IOException

Specified by:

write in interface DataOutput

Specified by:

write in interface ImageOutputStream

Specified by:

write in class ImageOutputStreamImpl

Throws:

IOException

length

public long length()

Specified by:

length in interface ImageInputStream

Overrides:

length in class ImageInputStreamImpl

seek

public void seek(long pos)
          throws IOException

Sets the current stream position and resets the bit offset to 0. It is legal to seeking past the end of the eraf; an EOFException will be thrown only if a read is performed. The eraf length will not be increased until a write is performed.

Specified by:

seek in interface ImageInputStream

Overrides:

seek in class ImageInputStreamImpl

Throws:

IndexOutOfBoundsException - if pos is smaller than the flushed position.

IOException - if any other I/O error occurs.

close

public void close()
           throws IOException

Closes the underlying EnhancedRandomAccessFile.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Specified by:

close in interface ImageInputStream

Overrides:

close in class ImageInputStreamImpl

Throws:

IOException - in case something bad happens.

getFile

public File getFile()

Retrieves the File we are connected to.

Specified by:

getFile in interface FileImageOutputStreamExt

Returns:

the associated File

dispose

public void dispose()

Disposes this FileImageInputStreamExtImpl by closing its underlying EnhancedRandomAccessFile.

toString

public String toString()

Provides a simple description for this ImageOutputStream.

Overrides:

toString in class Object

Returns:

a simple description for this ImageOutputStream.

getTarget

public File getTarget()

Allows us to access the underlying file.

Specified by:

getTarget in interface AccessibleStream<File>

Returns:

the underlying File.

getBinding

public Class<File> getBinding()

Description copied from interface: AccessibleStream

Retrieve the class for the target object.

Specified by:

getBinding in interface AccessibleStream<File>

Returns:

the class for the target object.
