Description

Packages

com.dautelle.math	Provides support for linear algebra.
com.dautelle.math.functions	Provides support for fairly simple symbolic math analysis (to solve algebraic equations, integrate, differentiate, calculate expressions, and so on).
com.dautelle.math.numbers	Provides common types of numbers (operable and real-time compliant).
com.dautelle.money	Provides support for monetary quantities and their currencies.
com.dautelle.physics	Provides support for physical quantities, automatic error calculation (including numeric errors), and dimension-checking done in the form of class-type checking.
com.dautelle.physics.models	Provides models for physical quantities.
com.dautelle.realtime	Provides real-time Context for higher performance and higher predictability of Java bytecode execution.
com.dautelle.util	Provides important classes either missing from the standard JDK library or for which the current JDK implementation has serious flaws.
com.dautelle.xml	Provides support for the encoding of objects, and the objects reachable from them, into XML; and the complementary reconstruction of the object graph from XML.
com.dautelle.xml.sax	Provides a XML RealtimeParser which does not create objects dynamically; this parser runs on average 2-3x faster than (the fastest) conventional SAX2 parser.
javax.units	Provides support for programatic unit handling (in conformance with the units specification currently being defined under JSR-108).

Java^TM Addition to Default Environment API.

License:

The library is cover under the LGPL license. This license puts few restrictions on usage of JADE, which is free for commercial use and distribution. The utility classes (package util) are public domain.

Static linking (e.g. using GNU Compiler for Java) is permitted for commercial products as long as the users can modify the JADE library and then relink to produce a modified executable containing the modified library (ref. LGPL paragraph 6). This requirement is easily satisfied without giving away the application source code by providing a pre-link (native binary archive) of the application without the library along with the library source code.

Overview:

Although Java^TM has been very successful on the server-side; It has few shortcomings limiting its adoption for others domains such as real-time, scientific or safety-critical software. For these, the JADE library provides important "pieces" missing from the Java^TM core library and making the Java^TM platform even more attractive. These new "pieces" are complementary and work closely together as illustrated by the following table:

Relationship	math	real-time	units	physics	money	xml
math	·	compliant	N/A	Operable	Operable	compliant
real-time	Object Factory	·	dimensions	ObjectFactory	ObjectFactory	RealtimeParser
units	N/A	N/A	·	Unit	Currency	N/A
physics	compliant	models	SI	·	Quantity	compliant
money	compliant	compliant	BaseUnit("¤")	Quantity	·	compliant
xml	Representable	sax	valueOf(CharSequence)	Representable	Representable	·

Configuration:

JADE's default configuration should satisfy most applications. Nonetheless, it is possible to change these defaults by setting the appropriate system properties (e.g. "java -Djade.concurrency=0 ..." to disable low-level concurrent executions).

System Property	Default (if not set)	Description
"jade.concurrency"	(Number of Processors) - 1	The maximum number of ConcurrentThread
"jade.factories"	1024	The maximum number of ObjectFactory
"jade.variables"	1024	The maximum number of LocalContext.Variable
