+/**
+ * Reference implementation of the Unicode 3.0 Bidi algorithm.
+ *
+ * <p>
+ * This implementation is not optimized for performance. It is intended
+ * as a reference implementation that closely follows the specification
+ * of the Bidirectional Algorithm in The Unicode Standard version 3.0.
+ * <p>
+ * <b>Input:</b><br>
+ * There are two levels of input to the algorithm, since clients may prefer
+ * to supply some information from out-of-band sources rather than relying on
+ * the default behavior.
+ * <ol>
+ * <li>unicode type array
+ * <li>unicode type array, with externally supplied base line direction
+ * </ol>
+ * <p><b>Output:</b><br>
+ * Output is separated into several stages as well, to better enable clients
+ * to evaluate various aspects of implementation conformance.
+ * <ol>
+ * <li>levels array over entire paragraph
+ * <li>reordering array over entire paragraph
+ * <li>levels array over line
+ * <li>reordering array over line
+ * </ol>
+ * Note that for conformance, algorithms are only required to generate correct
+ * reordering and character directionality (odd or even levels) over a line.
+ * Generating identical level arrays over a line is not required. Bidi
+ * explicit format codes (LRE, RLE, LRO, RLO, PDF) and BN can be assigned
+ * arbitrary levels and positions as long as the other text matches.
+ * <p>
+ * As the algorithm is defined to operate on a single paragraph at a time,
+ * this implementation is written to handle single paragraphs. Thus
+ * rule P1 is presumed by this implementation-- the data provided to the

+/*
+ * Comments by Sivan Toledo:
+ * I created this class in order to add to iText the ability to utilize
+ * OpenType fonts with CFF glyphs (these usually have an .otf extension).
+ * The CFF font within the CFF table of the OT font might be either a CID
+ * or a Type1 font. (CFF fonts may also contain multiple fonts; I do not
+ * know if this is allowed in an OT table). The PDF spec, however, only
+ * allow a CID font with an Identity-H or Identity-V encoding. Otherwise,
+ * you are limited to an 8-bit encoding.
+ * Adobe fonts come in both flavors. That is, the OTFs sometimes have
+ * a CID CFF inside (for Japanese fonts), and sometimes a Type1 CFF
+ * (virtually all the others, Latin/Greek/Cyrillic). So to easily use
+ * all the glyphs in the latter, without creating multiple 8-bit encoding,
+ * I wrote this class, whose main purpose is to convert a Type1 font inside
+ * a CFF container (which might include other fonts) into a CID CFF font
+ * that can be directly embeded in the PDF.
+ *
+ * Limitations of the current version:
+ * 1. It does not extract a single CID font from a CFF that contains that
+ * particular CID along with other fonts. The Adobe Japanese OTF's that
+ * I have only have one font in the CFF table, so these can be
+ * embeded in the PDF as is.
+ * 2. It does not yet subset fonts.
+ * 3. It may or may not work on CFF fonts that are not within OTF's.
+ * I didn't try that. In any case, that would probably only be
+ * useful for subsetting CID fonts, not for CFF Type1 fonts (I don't
+ * think there are any available.
+ * I plan to extend the class to support these three features at some
+ * future time.

+ * *
+ * Author: Ken Borgendale 10/9/91 Version 1.0 *
+ * *
+ * Function: *
+ * Convert a Windows .pfm (Printer Font Metrics) file to a *
+ * .afm (Adobe Font Metrics) file. The purpose of this is *
+ * to allow fonts put out for Windows to be used with OS/2. *
+ * *
+ * Syntax: *

+ * Copyright: *

+ * *
+ * This code is released for public use as long as the *
+ * copyright remains intact. This code is provided asis *
+ * without any warrenties, express or implied. *
+ * *
+ * Notes: *
+ * 1. Much of the information in the original .afm file is *
+ * lost when the .pfm file is created, and thus cannot be *
+ * reconstructed by this utility. This is especially true *
+ * of data for characters not in the Windows character set. *
+ * *
+ * 2. This module is coded to be compiled by the MSC 6.0. *
+ * For other compilers, be careful of the packing of the *
+ * PFM structure. *

+ * *
+ * Modifications by Rod Smith, 5/22/96 *
+ * *
+ * These changes look for the strings "italic", "bold", "black", *
+ * and "light" in the font's name and set the weight accordingly *
+ * and adds an ItalicAngle line with a value of "0" or "-12.00". *
+ * This allows OS/2 programs such as DeScribe to handle the bold *
+ * and italic attributes appropriately, which was not the case *
+ * when I used the original version on fonts from the KeyFonts *
+ * Pro 2002 font CD. *
+ * *
+ * I've also increased the size of the buffer used to load the *
+ * .PFM file; the old size was inadequate for most of the fonts *
+ * from the SoftKey collection. *
+ * *
+ * Compiled with Watcom C 10.6 *

+/**
+ * <h2>Ternary Search Tree.</h2>
+ *
+ * <p>A ternary search tree is a hibrid between a binary tree and
+ * a digital search tree (trie). Keys are limited to strings.
+ * A data value of type char is stored in each leaf node.
+ * It can be used as an index (or pointer) to the data.
+ * Branches that only contain one key are compressed to one node
+ * by storing a pointer to the trailer substring of the key.
+ * This class is intended to serve as base class or helper class
+ * to implement Dictionary collections or the like. Ternary trees
+ * have some nice properties as the following: the tree can be
+ * traversed in sorted order, partial matches (wildcard) can be
+ * implemented, retrieval of all keys within a given distance
+ * from the target, etc. The storage requirements are higher than
+ * a binary tree but a lot less than a trie. Performance is
+ * comparable with a hash table, sometimes it outperforms a hash
+ * function (most of the time can determine a miss faster than a hash).</p>
+ *
+ * <p>The main purpose of this java port is to serve as a base for
+ * implementing TeX's hyphenation algorithm (see The TeXBook,
+ * appendix H). Each language requires from 5000 to 15000 hyphenation
+ * patterns which will be keys in this tree. The strings patterns
+ * are usually small (from 2 to 5 characters), but each char in the
+ * tree is stored in a node. Thus memory usage is the main concern.
+ * We will sacrify 'elegance' to keep memory requirenments to the
+ * minimum. Using java's char type as pointer (yes, I know pointer
+ * it is a forbidden word in java) we can keep the size of the node
+ * to be just 8 bytes (3 pointers and the data char). This gives
+ * room for about 65000 nodes. In my tests the english patterns
+ * took 7694 nodes and the german patterns 10055 nodes,
+ * so I think we are safe.</p>
+ *
+ * <p>All said, this is a map with strings as keys and char as value.
+ * Pretty limited!. It can be extended to a general map by
+ * using the string representation of an object and using the
+ * char value as an index to an array that contains the object
+ * values.</p>
