Class Fragment

java.lang.Object
  org.activemath.presentation.Fragment

All Implemented Interfaces:

Serializable

public class Fragment
extends Object
implements Serializable

A transformed content item. Content is stored as bytes, supposed to be UTF-8 encoded. Implements Serializable for use as cache objects in org.apache.cache.Cache. Since we are not using a persistent cache, no care has been taken to provide a custum serialization. See Chapter 10 of "Effective Java" by Joshua Bloch.

public long getTimeStamp()

getContent

public byte[] getContent()

getContentUTF8

public String getContentUTF8()

Convert the content of this fragment as UTF-8 string. Takes about 15ms for 180KB buffer. This string is currently not stored because of excessive memory requirements (for storing n KB of HTML, we would need 3*n KB of storage).

Returns:

content of this fragment as UTF-8 string.

setContent

public void setContent(byte[] content)

Set the content for this fragment.

Parameters:

content - content as bytes

setTimeStamp

public void setTimeStamp(long timeStamp)
