A class representing an Image File Directory (IFD) from a TIFF 6.0 stream. The TIFF file format is described in more detail in the comments for the TIFFDescriptor class.
A TIFF IFD consists of a set of TIFFField tags. Methods are provided to query the set of tags and to obtain the raw field array. In addition, convenience methods are provided for acquiring the values of tags that contain a single value that fits into a byte, int, long, float, or double.
Every TIFF file is made up of one or more public IFDs that are joined in a linked list, rooted in the file header. A file may also contain so-called private IFDs that are referenced from tag data and do not appear in the main list.

The PDF architecture (1.4) supports 16-bit strings only with CID CFF fonts, not in Type-1 CFF fonts, so we convert the font to CID if it is in the Type-1 format.

A random Access File or an array This Class subsets a CFF Type Font. This Class subsets a CFF Type Font. The subset is preformed for CID fonts and NON CID fonts. The Charstring is subsetted for both types. For CID fonts only the FDArray which are used are embedded. The Lsubroutines of the FDArrays used are subsetted as well. The Subroutine subset supports both Type1 and Type2 formatting although only tested on Type2 Format. For Non CID the Lsubroutines are subsetted. On both types the Gsubroutines is subsetted. A font which was not of CID type is transformed into CID as a part of the subset process.

This class is a convenience method to sequentially calculate hash code of the object based on the field values. This class is a convenience method to sequentially calculate hash code of the object based on the field values. The result depends on the order of elements appended. The exact formula is the same as for . If you need order independent hash code just summate, multiply or XOR all elements. Suppose we have class: 

            class Thing {
            long id;
            String name;
            float weight;
            }
The hash code calculation can be expressed in 2 forms. For maximum performance: 

            public int hashCode() {
            int hashCode = HashCode.EMPTY_HASH_CODE;
            hashCode = HashCode.combine(hashCode, id);
            hashCode = HashCode.combine(hashCode, name);
            hashCode = HashCode.combine(hashCode, weight);
            return hashCode;
            }
For convenience: 

            public int hashCode() {
            return new HashCode().append(id).append(name).append(weight).hashCode();
            }

Justin Couch Alex Chaffee (alex@apache.org) Stephen Colebourne Bruno Lowagie (change Objects as keys into int values) Paulo Soares (added extra methods) The hash table data. The total number of entries in the hash table. The table is rehashed when its size exceeds this threshold. The table is rehashed when its size exceeds this threshold. (The value of this field is (int)(capacity * loadFactor).) The load factor for the hashtable. Constructs a new, empty hashtable with a default capacity and load factor, which is 20 and 0.75 respectively. Constructs a new, empty hashtable with the specified initial capacity and default load factor, which is 0.75. the initial capacity of the hashtable. Constructs a new, empty hashtable with the specified initial capacity and the specified load factor. the initial capacity of the hashtable. the load factor of the hashtable. Returns the number of keys in this hashtable. the number of keys in this hashtable. Tests if this hashtable maps no keys to values. true if this hashtable maps no keys to values; false otherwise. Tests if some key maps into the specified value in this hashtable. Tests if some key maps into the specified value in this hashtable. This operation is more expensive than the containsKey method. Note that this method is identical in functionality to containsValue, (which is part of the Map interface in the collections framework). a value to search for. true if and only if some key maps to the value argument in this hashtable as determined by the equals method; false otherwise. Returns true if this HashMap maps one or more keys to this value. Returns true if this HashMap maps one or more keys to this value. Note that this method is identical in functionality to contains (which predates the Map interface). value whose presence in this HashMap is to be tested. boolean true if the value is contained Tests if the specified int is a key in this hashtable. possible key. true if and only if the specified int is a key in this hashtable, as determined by the equals method; false otherwise. Returns the value to which the specified key is mapped in this map. a key in the hashtable. the value to which the key is mapped in this hashtable; 0 if the key is not mapped to any value in this hashtable. Increases the capacity of and internally reorganizes this hashtable, in order to accommodate and access its entries more efficiently. Increases the capacity of and internally reorganizes this hashtable, in order to accommodate and access its entries more efficiently. This method is called automatically when the number of keys in the hashtable exceeds this hashtable's capacity and load factor. Maps the specified key to the specified value in this hashtable. Maps the specified key to the specified value in this hashtable. The key cannot be null. The value can be retrieved by calling the get method with a key that is equal to the original key. the hashtable key. the value. the previous value of the specified key in this hashtable, or null if it did not have one. Removes the key (and its corresponding value) from this hashtable. Removes the key (and its corresponding value) from this hashtable. This method does nothing if the key is not present in the hashtable. the key that needs to be removed. the value to which the key had been mapped in this hashtable, or null if the key did not have a mapping.

Summary description for Properties. A character-stream reader that allows characters to be pushed back into the stream. @author Mark Reinhold @since JDK1.1 Pushback buffer Current position in buffer Creates a new pushback reader with a pushback buffer of the given size. The reader from which characters will be read The size of the pushback buffer Creates a new pushback reader with a one-character pushback buffer. The reader from which characters will be read Checks to make sure that the stream has not been closed. Reads a single character. The character read, or -1 if the end of the stream has been reached Reads characters into a portion of an array. Destination buffer Offset at which to start writing characters Maximum number of characters to read The number of characters read, or -1 if the end of the stream has been reached Pushes back a single character by copying it to the front of the pushback buffer. After this method returns, the next character to be read will have the value (char)c. The int value representing a character to be pushed back Pushes back a portion of an array of characters by copying it to the front of the pushback buffer. After this method returns, the next character to be read will have the value cbuf[off], the character after that will have the value cbuf[off+1], and so forth. Character array Offset of first character to push back Number of characters to push back Pushes back an array of characters by copying it to the front of the pushback buffer. After this method returns, the next character to be read will have the value cbuf[0], the character after that will have the value cbuf[1], and so forth. Character array to push back Closes the stream and releases any system resources associated with it. Once the stream has been closed, further read(), unread(), ready(), or skip() invocations will throw an IOException. Closing a previously closed stream has no effect.
