org.eclipse.jface.text.rules.FastPartitioner

A standard implementation of a document partitioner. It uses an {@link IPartitionTokenScanner} to scan the document and to determine thedocument's partitioning. The tokens returned by the scanner must return the partition type as their data. The partitioner remembers the document's partitions in the document itself rather than maintaining its own data structure.

To reduce array creations in {@link IDocument#getPositions(String)}, the positions get cached. The cache is cleared after updating the positions in {@link #documentChanged2(DocumentEvent)}. Subclasses need to call {@link #clearPositionCache()} after modifying the partitioner's positions.The cached positions may be accessed through {@link #getPositions()}.
