Method Detail

close

void close()
           throws java.io.IOException

Close the media asset

Throws:

java.io.IOException

exists

boolean exists()

Does the media asset exist

Returns:

true if media assets exists

getBasePath

String getBasePath()

Get the basePath for the random access reader

Returns:

Returns:

current byte location in the media asset

getMediaExtension

String getMediaExtension()

Get the media extension

Returns:

media extension

getMediaName

String getMediaName()

Get the media name

Returns:

media name

getPath

String getPath()

Get the unique path to the media asset item

Returns:

unique path to the media asset item

init

void init(IApplicationInstance appInstance,
          IMediaStream stream,
          String basePath,
          String mediaName,
          String mediaExtension)

Intialize RandomAccessReader

Parameters:

appInstance - application instance

stream - parent stream if one exists

basePath - basePath for IApplicationInstance

mediaName - media name

mediaExtension - media extension from mediaReaders

isOpen

boolean isOpen()

Is the media asset open

Returns:

true if media asset is open

lastModified

long lastModified()

Return the lastModified date (same format as File.lastModified)

Returns:

lastModified date (same format as File.lastModified)

length

long length()

Get the media asset length in bytes

Returns:

media asset length in bytes

open

void open()
          throws java.io.IOException

Open the media asset

Throws:

java.io.IOException

read

int read(byte[] buf,
         int off,
         int size)

Read bytes from the media asset

Parameters:

buf - buffer to fill

off - offset in buffer

size - size of block to read

Returns:

number of bytes read, -1 if failure

seek

void seek(long pos)

Seek to a position in the media asset
