Package Summary Overview Summary

class:StringContent [NONE]

All Implemented Interfaces:

Serializable, AbstractDocument.Content
```
public final class StringContent
extends Object
implements AbstractDocument.Content, Serializable
```
An implementation of the AbstractDocument.Content interface that is a brute force implementation that is useful for relatively small documents and/or debugging. It manages the character content as a simple character array. It is also quite inefficient.
It is generally recommended that the gap buffer or piece table implementations be used instead. This buffer does not scale up to large sizes.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

Returns the length of the content.

Specified by:

length in interface AbstractDocument.Content

Returns:

the length >= 1

Removes part of the content. where + nitems must be < length().

Specified by:

remove in interface AbstractDocument.Content

Parameters:

where - the starting position >= 0

nitems - the number of characters to remove >= 0

Returns:

an UndoableEdit object for undoing

Throws:

BadLocationException - if the specified position is invalid

```
Retrieves a portion of the content. where + len must be <= length().

Specified by:

getString in interface AbstractDocument.Content

Parameters:

where - the starting position >= 0

len - the length to retrieve >= 0

Returns:

a string representing the content; may be empty

Throws:

Specified by:

getChars in interface AbstractDocument.Content

Parameters:

where - the starting position >= 0

len - the number of characters to retrieve >= 0

chars - the Segment object to return the characters in

Throws:

createPosition
```
public Position createPosition(int offset)
                        throws BadLocationException
```
Creates a position within the content that will track change as the content is mutated.

Specified by:

createPosition in interface AbstractDocument.Content

Parameters:

offset - the offset to create a position for >= 0

Returns:

the position

Throws:

BadLocationException - if the specified position is invalid

method:getPositionsInRange(java.util.Vector, int, int) [NONE]

getPositionsInRange
```
protected Vector getPositionsInRange(Vector v,

                                     int length)
```
Returns a Vector containing instances of UndoPosRef for the Positions in the range offset to offset + length. If v is not null the matching Positions are placed in there. The vector with the resulting Positions are returned.
This is meant for internal usage, and is generally not of interest to subclasses.

Parameters:

v - the Vector to use, with a new one created on null

offset - the starting offset >= 0

length - the length >= 0

Returns:

the set of instances
