Top-level util package are classes that are useful throughout the project. These classes are
generally generic enough to be useful in any project and should be contributed elsewhere!

ClassDescriptionUtility classes for dealing with arrays.Signifies that a public API (public class, method or field) is subject to incompatible changes, or even removal, in a future release.Manage operations dealing with bit-mapped fields.Returns immutable Bitfield instances.representation of a byte (8-bit) field at a fixed location within a byte arrayUtilities for working with Microsoft CodePages.Helper for fetching int values from system propertiesDefault implementation of the
TempFileCreationStrategyused byTempFile: Files are collected into one directory and by default are deleted on exit from the VM.Implementors of this interface allow client code to 'delay' writing to a certain section of a data output stream.
A typical application is for writing BIFF records when the size is not known until well after the header has been written.This is similar toRecordFormatException, except this is thrown when there's a higher order problem with parsing a document beyond individual records.Dump out the aggregated escher recordsbehavior of a field at a fixed location within a byte arraydump data in hexadecimal formatUtilities to read hex from files.representation of an integer (32-bit) field at a fixed location within a byte arrayProgram elements annotated @Internal are intended for POI internal use only.A List of int's; as full an implementation of the java.util.List interface as possible, with an eye toward minimal creation of objects the mimicry of List is as follows: if possible, operations designated 'optional' in the List interface are attempted wherever the List interface refers to an Object, substitute int wherever the List interface refers to a Collection or List, substitute IntList the mimicry is not perfect, however: operations involving Iterators or ListIterators are not supported remove(Object) becomes removeValue to distinguish it from remove(int index) subList is not supportedIntMapper<T>A List of objects that are indexed AND keyed by an int; also allows for getting the index of a value in the lista utility class for handling little-endian numbers, which the 80x86 world is replete with.Exception to handle buffer underrunsAdapts a plain byte array toLittleEndianInputAdapts a plain byte array toLittleEndianOutputa repository for constants shared by classes within this packageWraps anInputStreamprovidingLittleEndianInputLocale CollectionThis utility class is used to set locale and time zone settings beside of the JDK internalLocale.setDefault(Locale)andTimeZone.setDefault(TimeZone)methods, because the locale/time zone specific handling of certain office documents - maybe for different time zones / locales ...representation of a long (16-bit) field at a fixed location within a byte arrayThis class provides common functionality for the various LZW implementations in the different file formats.This feature has not been implemented yet.A common exception thrown by our binary format parsers (especially HSSF and DDF), when they hit invalid format or data when processing a record.Program elements annotated @Removal track the earliest final release when a deprecated feature will be removed.Simple FilterInputStream that can replace occurrences of bytes with something else.Wrapper of InputStream which provides Run Length Encoding (RLE) decompression on the fly.representation of a short (16-bit) field at a fixed location within a byte arrayDeprecated.Collection of string handling utilitiesMarking class for elements to be ignored by the forbidden apis checkInterface for creating temporary files.Interface used by theTempFileutility class to create temporary files.Helper methods for working with javax.xml classes.
