Method Detail

getOutputStream

public CachedOutputStream getOutputStream()
                                   throws java.io.IOException

Get a CachedOutputStream.

The typical usecase for this is to later use it to get a CachedInputStream from it.

Specified by:

getOutputStream in interface CachedStream

Throws:

java.io.IOException

getInputStream

public CachedInputStream getInputStream(CachedOutputStream cout)
                                 throws java.io.IOException

Get a rewindable input stream from the given CachedOutputStream.

Specified by:

getInputStream in interface CachedStream

Throws:

java.io.IOException - if the CachedOutputStream is not of the correct type (not from the same cache) or if an underlying IOException happens.

getInputStream

public CachedInputStream getInputStream(java.io.InputStream is)
                                 throws java.io.IOException

Get a rewindable inputstream from the given input stream, if the stream is a Rewindable input stream, it is just returned.

Specified by:

getInputStream in interface CachedStream

Throws:

java.io.IOException

rewind

public void rewind(java.io.InputStream is)
            throws java.io.IOException

Rewind this stream if it is rewindable, otherwise throw an IOException.

Specified by:

rewind in interface CachedStream

Throws:

java.io.IOException

setProperty

public void setProperty(java.lang.String name,
                        java.lang.String value)

Empty implementation.

Specified by:

setProperty in interface CachedStream

getProperty

public java.lang.String getProperty(java.lang.String name)

Chech if property is set, allways returns null.

Specified by:

getProperty in interface CachedStream
