Class MathExpressionParser<T,M,F,P>

java.lang.Object

org.vesalainen.grammar.math.MathExpressionParser<T,M,F,P>

Type Parameters:

T - Type type

M - Method type

F - Field type

P - Parameter type

All Implemented Interfaces:

org.vesalainen.grammar.math.MathExpressionParserIntf<T,M,F,P>

public abstract class MathExpressionParser<T,M,F,P>
extends Object
implements org.vesalainen.grammar.math.MathExpressionParserIntf<T,M,F,P>

MathExpressionParser parses math expression written in java style with some exceptions. Expressions are number or boolean valued. Most java.lang.Math methods can be used in expression.

Example: 1.2 * cos(x1)

Variable names follow java identifier ruling. Variables starting with '$' are reserved.

Boolean valued example: x > y && sin(z) > 0
