Constructor Detail

ImageRawStream

public ImageRawStream(ImageInfo info,
                      ImageFlavor flavor,
                      ImageRawStream.InputStreamFactory streamFactory)

Main constructor.

Parameters:

info - the image info object

flavor - the image flavor for the raw image

streamFactory - the InputStreamFactory that is used to create InputStream instances

ImageRawStream

public ImageRawStream(ImageInfo info,
                      ImageFlavor flavor,
                      java.io.InputStream in)

Constructor for a simple InputStream as parameter.

Parameters:

info - the image info object

flavor - the image flavor for the raw image

in - the InputStream with the raw content

Method Detail

getFlavor

public ImageFlavor getFlavor()

Returns the flavor of the image.

Returns:

the image flavor

getMimeType

public java.lang.String getMimeType()

Returns the MIME type of the stream data.

Returns:

the MIME type

isCacheable

public boolean isCacheable()

Indicates whether the Image instance is cacheable in memory.

Returns:

true if the Image is cacheable

setInputStreamFactory

public void setInputStreamFactory(ImageRawStream.InputStreamFactory factory)

Sets the InputStreamFactory to be used by this image. This method allows to replace the original factory.

Parameters:

factory - the new InputStreamFactory

createInputStream

public java.io.InputStream createInputStream()

Returns a new InputStream to access the raw image.

Returns:

the InputStream

writeTo

public void writeTo(java.io.OutputStream out)
             throws java.io.IOException

Writes the content of the image to an OutputStream. The OutputStream in NOT closed at the end.

Parameters:

out - the OutputStream

Throws:

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