NPOI.Util
a utility class for handling little-endian numbers, which the 80x86 world is
replete with. The methods are all static, and input/output is from/to byte
arrays, or from InputStreams.

Logs a formated message. The message itself may contain %

the placeholder by looking at the type of parameter passed to
obj1.
If the parameter is an array, it traverses the array first and
matches parameters sequentially against the array items.
Otherwise the parameters after message are matched
in order.
If the place holder matches against a number it is printed as a
whole number. This can be overridden by specifying a precision
in the form %n.m where n is the padding for the whole part and
m is the number of decimal places to display. n can be excluded
if desired. n and m may not be more than 9.

Obtain the value for the specified BitField, appropriately
shifted right. Many users of a BitField will want to treat the
specified bits as an int value, and will not want to be aware
that the value is stored as a BitField (and so shifted left so
many bits)

Obtain the value for the specified BitField, unshifted

Are all of the bits set or not? This is a stricter test than
isSet, in that all of the bits in a multi-bit set must be set
for this method to return true
the int data containing the bits we're interested in
true if all of the bits are set otherwise, false.
Is the field set or not? This is most commonly used for a
single-bit field, which is often used to represent a boolean
value; the results of using it for a multi-bit field is to
determine whether *any* of its bits are set
the int data containing the bits we're interested in
true if any of the bits are set; otherwise, false.
Set the bits.

A Logger class that strives to make it as easy as possible for
developers to write Log calls, while simultaneously making those
calls as cheap as possible by performing lazy evaluation of the Log
message.

Logs a formated message. The message itself may contain %
characters as place holders. This routine will attempt to match
the placeholder by looking at the type of parameter passed to
obj1.
If the parameter is an array, it traverses the array first and
matches parameters sequentially against the array items.
Otherwise the parameters after message are matched
in order.
If the place holder matches against a number it is printed as a
whole number. This can be overridden by specifying a precision
in the form %n.m where n is the padding for the whole part and
m is the number of decimal places to display. n can be excluded
if desired. n and m may not be more than 9.
If the last parameter (after flattening) is a Exception it is
Logged specially.

is multidimensional.
-or-
is equal to or greater than the length of .
-or-
The number of elements in the source is greater than the available space from to the end of the destination .
The type of the source cannot be cast automatically to the type of the destination .
Returns an enumerator that iterates through a collection.
An object that can be used to iterate through the collection.
Removes the specified o.
The o.
Gets the number of elements contained in the .
The number of elements contained in the .
Gets a value indicating whether access to the is synchronized (thread safe).
true if access to the is synchronized (thread safe); otherwise, false.
Gets an object that can be used to synchronize access to the .
An object that can be used to synchronize access to the .
A List of objects that are indexed AND keyed by an int; also allows for getting
the index of a value in the list
I am happy is someone wants to re-implement this without using the
internal list and hashmap. If so could you please make sure that
you can add elements half way into the list and have the value-key mappings

File CRC
the input file
Stream CRC
the input stream
Creates a temporary file. Files are collected into one directory and by default are
deleted on exit from the VM. Files can be kept by defining the system property
poi.keep.tmp.files.
Dont forget to close all files or it might not be possible to delete them.
Reads all the data from the input stream, and returns
the bytes Read.
The stream.

Reads the fully.
The stream.
The b.
Same as the normal
in.Read(b, off, len)
, but tries to ensure that the entire len number of bytes is Read.
If the end of file is reached before any bytes are Read, returns -1.
If the end of the file is reached after some bytes are
Read, returns the number of bytes Read.
If the end of the file isn't reached before len
bytes have been Read, will return len bytes.
