append

public TextSpan append(char ch)
                throws gzz.errors.ImmutableException

Do compare by identity for now! public boolean equals(Object o) { if(!(o instanceof ScrollBlock)) return false; if(this == o) return true; if(mediaserverId == null) return false; ScrollBlock sb = (ScrollBlock)o; return sb.getID().equals(getID()); } public int hashCode() { if(mediaserverId == null) throw new Error("Not finalized-- cannot hash yet"); return getID().hashCode(); } public String toString() { return "TransientTextScroll<"+getID()+">"; }

getCurrent

public Span getCurrent()

Description copied from interface: ScrollBlock

Get the current contents of this block as a single span of the appropriate type.

Specified by:

getCurrent in interface ScrollBlock

getSpan

public Span getSpan(int offs1,
                    int offs2)

Description copied from interface: TextScrollBlock

Get a span that represents the given range inside this scrollblock. Equivalent to getCurrent().subSpan(offs1,offs2).

Specified by:

getSpan in interface TextScrollBlock

Parameters:

offs1 - The offset the span should start at.

offs2 - The one-past-end offset.

isFinalized

public boolean isFinalized()

Description copied from interface: ScrollBlock

Whether this block has been finalized or whether more can be appended.

Specified by:

isFinalized in interface ScrollBlock

getID

public java.lang.String getID()

Description copied from interface: ScrollBlock

Get the globally unique identifier of this block. XXX Exact semantics, tmp ids

Specified by:

getID in interface ScrollBlock

saveOrGetId

public Mediaserver.Id saveOrGetId(Mediaserver saveTo)
                           throws java.io.IOException

Description copied from interface: ScrollBlockManager.MediaserverScrollBlock

Get the Mediaserver id of this block; save when not saved yet.

Specified by:

java.io.IOException

getCharArray

public char[] getCharArray()

Description copied from interface: TextScrollBlock

Get the internal character array of this scrollblock. This is used for speeding up drawing strings from a TextScrollBlock by being able to give a scrollblock and two offsets to the drawing routines.

THE RETURNED CHARACTER ARRAY MUST NOT BE MODIFIED UNDER ANY CIRCUMSTANCES.
