DateUtil (Geotools modules 27-SNAPSHOT API)

Object
- DateUtil

```
public abstract class DateUtil
extends Object
```
Utility class supplying static methods. Date serialization is based on the algorithms published by Peter Baum (http://www.capecod.net/~pbaum). All date handling is done according to the W3C Schema specification, which uses a proleptic Gregorian calendar with no year 0. Note that this differs from the Java date handling, which uses a discontinuous Gregorian calendar.

    Parameters:
    
    time - time to be converted
    
    Returns:
    
    converted time text

```
public static boolean isEqual(Object a,
                              Object b)
```
    General object comparison method. Don't know why Sun hasn't seen fit to include this somewhere, but at least it's easy to write (over and over again).
    
    Parameters:
    
    a - first object to be compared
    
    b - second object to be compared
    
    Returns:
    
    true if both objects are null, or if a.equals(b); false otherwise
  - enumValue
```

                     throws IllegalArgumentException
```
    Find text value in enumeration. This first does a binary search through an array of allowed text matches. If a separate array of corresponding values is supplied, the value at the matched position is returned; otherwise the match index is returned directly.

    target - text to be found in enumeration
    
    enums - ordered array of texts included in enumeration
    
    vals - array of values to be returned for corresponding text match positions (position returned directly if this is null)

    enumeration value for target text
    
    Throws:
    
    IllegalArgumentException - if target text not found in enumeration

    Parameters:
    
    text - text to be parsed (may include extra characters)
    
    Returns:
    
    byte array of data

public static byte[] deserializeBase64(String text)
                                throws IllegalArgumentException
```
    Parse base64 data from text. This converts the base64 data into a byte array of the appopriate length. In keeping with the recommendations,
    
    Parameters:
    
    text - text to be parsed (may be null, or include extra characters)
    
    Returns:
    
    byte array of data
    
    Throws:
    
    IllegalArgumentException - if invalid character in base64 representation
  - encodeChunk
```
public static void encodeChunk(int base,
                               byte[] byts,
                               StringBuffer buff)
```
    Encode a chunk of data to base64 encoding. Converts the next three bytes of data into four characters of text representation, using padding at the end of less than three bytes of data remain.
    
    Parameters:
    
    base - starting offset within byte array
    
    byts - byte data array
    
    buff - buffer for encoded text
  - serializeBase64
```
public static String serializeBase64(byte[] byts)
```
    Serialize byte array to base64 text. In keeping with the specification, this adds a line break every 76 characters in the encoded representation.
    
    Parameters:
    
    byts - byte data array
    
    Returns:
    
    base64 encoded text
  - arrayListFactory

public static List arrayListFactory()
```
    Factory method to create a java.util.ArrayList as the implementation of a java.util.List.
    
    Returns:
    
    new java.util.ArrayList
