Class CellFormatPart

java.lang.Object
  org.apache.poi.ss.format.CellFormatPart

public class CellFormatPart
extends java.lang.Object

Objects of this class represent a single part of a cell format expression. Each cell can have up to four of these for positive, zero, negative, and text values.

Each format part can contain a color, a condition, and will always contain a format specification. For example "[Red][>=10]#" has a color ([Red]), a condition (>=10) and a format specification (#).

This class also contains patterns for matching the subparts of format specification. These are used internally, but are made public in case other code has use for them.
