com.intellij.openapi.editor.ex.util.ShortBasedStorage

All Implemented Interfaces:

DataStorage

Direct Known Subclasses:

TextMateLexerDataStorage

public class ShortBasedStorage
extends java.lang.Object
implements DataStorage

SegmentArrayWithData storage based on the short array. It allows to store one short per segment which is enough for storing IElementType index and and restartability of the state (positive values are for initial state).
