Package oracle.javatools.buffer

The TextBuffer package assists in the manipulation of in-memory text content, whether it is read-only text, or read-write text.

Interface Summary

Interface	Description
GuardedTextBufferListener	Listener to be notified when the guarded sections of a GuardedTextBuffer have changed.
LineMap	A LineMap is an interface for accessing the line structure information of a TextBuffer.
OffsetMark	The OffsetMark is used by the TextBuffer to provide bookmark services.
ReadTextBuffer	The ReadTextBuffer interface provides a subset of the TextBuffer methods for read-only access to text data.
ReadWriteLockImplementation
TextBuffer	The TextBuffer interface describes a class which can be used for managing the raw text content of a document.
TextBufferListener	The TextBufferListener interface should be implemented by observers interested in receiving notifications of changes to the associated TextBuffer.
WriteLockRequestListener	A listener notified by a ReadWriteLock when a thread requests a write lock.

Class Summary

Class	Description
AbstractTextBuffer	The AbstractTextBuffer class is a starting point for classes implementing the TextBuffer interface.
AbstractTextBuffer.UndoState	The UndoState is a layer of indirection between the TextBuffer and UndoableTextEdit's to allow undo's to be detached from the TextBuffer and reattach to a TextBuffer with the same buffer contents.
CharArrayReadTextBuffer	The CharArrayReadTextBuffer is a wrapper implementation that provides a ReadTextBuffer interface on top of a String datasource.
ForwardingTextBufferListener	A support class to forward text buffer events for a decorating text buffer.
GuardedTextBuffer	A TextBuffer that decorates another TextBuffer to prevent modification in certain 'guarded' regions.
MultiLock	Acquires and releases a set of ReadWriteLock as a unit.
OffsetMarkComparator	Compares two OffsetMarks to determine their order with respect to both offset and bias.
OffsetRegion	A contiguous section of offsets in a TextBuffer.
OffsetRegionChain	A mutable collection of regions, each bounded by OffsetMarks.
ReadTextBufferDecorator	The ReadTextBufferDecorator is a base decorator for a ReadTextBuffer.
ReadWriteLock	The ReadWriteLock class is an implementation of a reentrant multiple-reader/single-writer lock.
SafeArrayList	The SafeArrayList is an array List implementation that provides basic thread-safety by implementing a copy-on-write scheme.
SafeArrayList.SafeListIterator	A list iterator implementation based on a static array.
TextBufferDecorator	The TextBufferDecorator is a base decorator for a TextBuffer.
TextBufferFactory	The TextBufferFactory is a static factory class for creating TextBuffer instances for use.
Util	Buffer related utilities.
Utilities	The Utilities is a static utility class for TextBuffer instances.

Enum Summary

Enum	Description
ReadWriteLock.Implementation	An enumeration of the implementation types for a ReadWriteLock.
ReadWriteLock.Options	An enumeration of the configuration options for a ReadWriteLock.

Exception Summary

Exception	Description
ExpiredTextBufferException	An ExpiredTextBufferException is thrown when clients attempt to access an ExpirableTextBufferSnapshot after that snapshot has expired, due to the underlying text buffer being modified.
GuardedException	Exception thrown when an attempt is made to modify an offset in guarded section of a buffer.
ReadOnlyException	An ReadOnlyException is thrown when clients attempt to modify a TextBuffer instance marked as read only.

Package oracle.javatools.buffer Description

The TextBuffer package assists in the manipulation of in-memory text content, whether it is read-only text, or read-write text. All text data is stored in normal Java Unicode format as a sequence of char's.

Text buffers can be accessed through two interfaces:

• ReadTextBuffer: The first interface provides read-only access to the contents of the text buffer.
• TextBuffer: The second interface provides full read-write access to the contents of the text buffer.

To create a TextBuffer instance or ReadTextBuffer, use the TextBufferFactory factory class. For more details about how to use this package, please refer to the JavaDoc for these two interfaces.
