Interface | Description |
---|---|
Expression |
An Expression represents a mathematical expression such as "x+1" or
"3" or "sin(x*ln(x)-3*abs(x/4))".
|
ExpressionCommand |
An ExpressionCommand can occur as a command in an ExpressionProgram.
|
Function |
A Function is a mathematical real-valued function of zero or more
real-valued arguments.
|
MathObject |
A MathObject is just an object that has setName and getName methods.
|
ParserExtension |
A ParserExtension can be defined to add new capabilities to a
standard Parser.
|
Value |
An object of type Value has a real-number value that can be retrieved by
calling the getVal() method.
|
Class | Description |
---|---|
Cases |
An object of type Cases stores a list of "case values" that is generated
while an expression is being evaluated using the routine Expression.getValuesWithCases().
|
ConditionalExpression |
A "conditional expression" is an expression using the "?" operator, such as "(x > 0)? x : -x"
or "x <> 3 ? 1 / (x - 3)".
|
Constant |
A Constant is a Value that represents a constant real number.
|
ExpressionProgram |
An ExprssionProgram represents a mathematical expression such as "3" or "sin(x^2)", stored
in the form of a program for a stack machine.
|
NumUtils |
This class provides a few static functions for converting real numbers
to strings and strings to real numbers.
|
Parser |
A Parser can take a string and compile it into an ExpressionProgram.
|
ParserContext |
A ParserContext holds all the state data for a parsing operation, including the
string that is being parsed, a pointer to the current position in that string,
and the most recently parsed token from the string.
|
SimpleFunction |
An object belonging to this class is a function of one or more variables.
|
StackOfDouble |
A standard stack of values of type double, which can grow to arbitrary size.
|
StandardFunction |
This class exists to associate standard functions, such as sin and abs, with
their names.
|
SymbolTable |
A symbol table contains MathObjects, associating them
with their names.
|
ValueMath |
A ValueMath object is an easy way to create Value objects that are computed
from other Value objects.
|
Variable |
A Variable is a Value object whose value can be changed.
|
Exception | Description |
---|---|
ParseError |
Represents a syntax error that is found while a string is being parsed.
