protected java.lang.ref.ReferenceQueue	referenceQueue The reference queue.
protected AWTGlyphGeometryCache.Entry[]	table The underlying array

Constructor Summary

AWTGlyphGeometryCache()
Creates a new AWTGlyphGeometryCache.

AWTGlyphGeometryCache(int c)
Creates a new AWTGlyphGeometryCache.

Method Summary

void	clear() Clears the table.
AWTGlyphGeometryCache.Value	get(char c) Gets the value of a variable
protected int	hashCode(char c) Computes a hash code corresponding to the given objects.
AWTGlyphGeometryCache.Value	put(char c, AWTGlyphGeometryCache.Value value) Sets a new value for the given variable
protected void	rehash() Rehash the table
protected void	removeClearedEntries() Removes the cleared entries.
