Method Detail

buildUri

public static final java.lang.String buildUri(java.lang.String uri,
                                              java.util.HashMap<java.lang.String,java.lang.String> map)
                                       throws java.lang.IllegalArgumentException

Throws:

java.lang.IllegalArgumentException

public static void printDebugHeaderToConsole(java.lang.String msg)

getDebugHeaderString

public static java.lang.String getDebugHeaderString(java.lang.String msg)

getObjectRay

public static java.lang.Object[] getObjectRay(java.lang.Object... args)

listOfLogRecordToString

public static java.lang.String listOfLogRecordToString(java.util.List<java.util.logging.LogRecord> list)

Turns a list of LogRecord objects into a string for debug purposes

mapToString

public static java.lang.String mapToString(java.util.Map map)

listToString

public static java.lang.String listToString(java.util.List list)

arrayToString

public static java.lang.String arrayToString(java.lang.Object[] args)

isStringInList

public static boolean isStringInList(java.lang.String item,
                                     java.util.List<java.lang.String> list)

isObjectInList

public static <T> boolean isObjectInList(T item,
                                         java.util.List<T> list)

isObjectInArray

public static <T> boolean isObjectInArray(T item,
                                          T[] list)

getCallerMethodName

public static java.lang.String getCallerMethodName()

getCallerClassName

public static java.lang.String getCallerClassName()

getClassNameFromStackTrace

public static java.lang.String getClassNameFromStackTrace(int depth)

toArrayListFromObjectRay

public static java.util.ArrayList<java.lang.String> toArrayListFromObjectRay(java.lang.Object[] objRay)

getTime

public static java.lang.String getTime()

this method returns the current time in

fileToByteBuffer

public static ByteBuffer fileToByteBuffer(java.lang.String fileName)

this method reads a file and returns a ByteBuffer of the contents of this file.

fileToBytes

public static byte[] fileToBytes(java.lang.String fileName)

this method reads a file and returns a byte[] of the contents of this file.

fileToBytes

public static byte[] fileToBytes(java.lang.String fileName,
                                 java.util.Map<java.lang.String,ByteBuffer> fileCache)

this method reads a file and returns it as a byte array, but it uses a Map for a fileCache

fileToByteBuffer

public static ByteBuffer fileToByteBuffer(java.lang.String fileName,
                                          java.util.Map<java.lang.String,ByteBuffer> fileCache)

this method reads a file and returns it as a ByteBuffer, but it uses a Map for a fileCache

getString

public static java.lang.String getString(java.util.Map m,
                                         java.lang.Object key)

this method does away with a NullPointerException that might get thrown (incorrectly semantically speaking) when the following call is made: (String)Map.get("nonexistentkey");. The NullPointerException gets thrown because you can't typecast NULL. So the code simply checks to see if get(key) returns a null; and if it does, merely returns null; else returns the String representation of the object.s

getTokens

public static java.lang.String[] getTokens(java.lang.String s,
                                           java.lang.String delim)

this is just a convenience method to tokenize a string using the services of TheStringTokenizer class.
