Interface Summary

Interface	Description
MultiDimComparable<T>	This interface represents an object which can be compared in many dimensions or in many ways.
MultiDimSort	This interface represents a sort on multidimensional arrays.
MultivariateFunction	Represents a function of multiple variables.

Class Summary

Class	Description
AbstractChrono	AbstractChrono is a class that acts as an interface to the system clock and calculates the CPU or system time consumed by parts of a program.
ArithmeticMod	This class provides facilities to compute multiplications of scalars, of vectors and of matrices modulo m.
BatchSort	This class implements a MultiDimSort that performs a batch sort on the arrays.
BitMatrix	This class implements matrices of bits of arbitrary dimensions.
BitVector	This class implements vectors of bits and the operations needed to use them.
Chrono	The Chrono class extends the AbstractChrono class and computes the CPU time for the current thread only.
ChronoSingleThread	Deprecated
ClassFinder	Utility class used to convert a simple class name to a fully qualified class object.
DMatrix	This class implements a few methods for matrix calculations with double numbers.
DoubleArrayComparator	An implementation of Comparator which compares two double arrays by comparing their i-th element, where i is given in the constructor.
GlobalCPUTimeChrono	Extends the AbstractChrono class to compute the global CPU time used by the Java Virtual Machine.
Introspection	Provides utility methods for introspection using Java Reflection API.
JDBCManager	This class provides some facilities to connect to a SQL database and to retrieve data stored in it.
Misc	This class provides miscellaneous functions that are hard to classify.
MultiDimComparator<T extends MultiDimComparable<? super T>>	This class defines a bridge between our interface MultiDimComparable and the classic Comparator in Java.
Num	This class provides a few constants and some methods to compute numerical quantities such as factorials, combinations, gamma functions, and so on.
OneDimSort	This class implements a MultiDimSort that simply sorts the arrays according to one dimension specified in the constructor.
PrintfFormat	This class acts like a StringBuffer which defines new types of append methods.
RatioFunction	Represents a function computing a ratio of two values.
RootFinder	This class provides methods to solve non-linear equations.
SplitSort	This class implements a MultiDimSort that performs a split sort on the arrays.
SystemTimeChrono	Extends the AbstractChrono class to compute the total system time using Java's builtin System.nanoTime.
TableFormat	This class provides methods to format arrays and matrices into Strings in different styles.
TextDataReader	Provides static methods to read data from text files.
ThreadCPUTimeChrono	Extends the AbstractChrono class to compute the CPU time for a single thread.
TransformingList<OE,IE>	Represents a list that dynamically transforms the elements of another list.

Enum Summary

Enum	Description
TimeUnit

Exception Summary

Exception	Description
NameConflictException	This exception is thrown by a ClassFinder when two or more fully qualified class names can be associated with a simple class name.

Package umontreal.iro.lecuyer.util Description

This package contains utility classes used in the Java software developed in the simulation laboratory of the DIRO, at the Université de Montréal. Many of these tools were originally implemented in the Modula-2 language and have been translated in C and then in Java, with some adaptations along the road.
