Constructor Detail

QuartaryOperator

public QuartaryOperator(Expression e1,
                        Expression e2,
                        Expression e3,
                        Expression e4)

Creates a QuartaryOperator object working on four given Expression objects.

Parameters:

e1 - An Expression object.

e2 - Another Expression object.

e3 - Yet another Expression object.

e4 - And even yet another Expression object.

Since:

1.0

Method Detail

setSecondOperand

public void setSecondOperand(Expression e2)

Assigns the second operand that the QuartaryOperator object works on to a given Expression object.

Parameters:

e2 - An Expression object.

See Also:

getSecondOperand()

setThirdOperand

public void setThirdOperand(Expression e3)

Assigns the third operand that the QuartaryOperator object works on to a given Expression object.

Parameters:

e3 - An Expression object.

See Also:

getThirdOperand()

setFourthOperand

public void setFourthOperand(Expression e4)

Assigns the fourth operand that the QuartaryOperator object works on to a given Expression object.

Parameters:

e4 - An Expression object.

See Also:

getThirdOperand()

getSecondOperand

public Expression getSecondOperand()

Returns the second operand that the QuartaryOperator object works on.

Returns:

An Expression object that represents the second operand that the QuartaryOperator object works on.

See Also:

setSecondOperand(org.jscience.mathematics.analysis.expressions.Expression)

getThirdOperand

public Expression getThirdOperand()

Returns the third operand that the QuartaryOperator object works on.

Returns:

An Expression object that represents the third operand that the QuartaryOperator object works on.

See Also:

setFourthOperand(org.jscience.mathematics.analysis.expressions.Expression)

isDifferentiable

public boolean isDifferentiable()

Default implementation of method isDifferentiable which assumes that the BinaryOperator object is differentiable. All nondifferentiable QuartaryOperators must overrride this implementation.

See Also:

Expression.isDifferentiable()

isExpandable

public boolean isExpandable()

Default implementation of method isExpandable which assumes that the QuartaryOperator object is expandable. All nonexpandable QuartaryOperators must overrride this implementation.

Returns:

DOCUMENT ME!

See Also:

Expression.isExpandable()

diff

public Expression diff(NamedDataExpression x)

Class QuartaryOperator provides a default diff method for use by nondifferentiable objects. All differentiable objects must override this diff method.

Parameters:

x - DOCUMENT ME!

Returns:

DOCUMENT ME!

toTaylorMap

public java.lang.String toTaylorMap()

Dummy implementation for classes that are not expandable.

Returns:
