          Description

Interface Summary
MultivariateFunction Represents a function of multiple variables.
 

Class Summary
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.
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.
Num This class provides a few constants and some methods to compute numerical quantities such as factorials, combinations, gamma functions, and so on.
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.
Systeme This class provides a few tools related to the system or the computer.
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
TimeUnit  
 

Exception Summary
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.
