## org.apache.batik.gvt.font
Class AWTGlyphGeometryCache

    java.lang.Object
      org.apache.batik.gvt.font.AWTGlyphGeometryCache

public class AWTGlyphGeometryCache
extends java.lang.Object

This class represents a doubly indexed hash table, which holds soft references to the contained glyph geometry informations.

Nested Class Summary
`protected class` | `AWTGlyphGeometryCache.Entry` To manage collisions
`static class` | `AWTGlyphGeometryCache.Value` The object that holds glyph geometry.

Field Summary
`protected int` | `count` The number of entries
`protected static int` | `INITIAL_CAPACITY` The initial capacity
`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.
`int` | `size()` Returns the size of this table.
