Constructor Details

AlgebraicTree

public AlgebraicTree(String formula)

Constructs a new instance of the AlgebraicTree class with the specified formula.

Parameters:

formula - the formula used to create the algebraic tree

AlgebraicTree

public AlgebraicTree(String formula,
 Map<String,Double> parametersValues)

Constructs a new instance of the AlgebraicTree class with the specified formula and parameter values.

Parameters:

formula - the formula used to create the algebraic tree

parametersValues - a map of parameter values

Method Details

removeSpaces

public void removeSpaces()

Removes all spaces, newlines, carriage returns, and tabs from the formula string. If the formula is null, it sets it to an empty string.

setParameter

public void setParameter(String s,
 Double d)

Sets the parameter value for a given parameter name.

Parameters:

s - the parameter name

d - the parameter value

construct

public AlgebraicTree construct()
                        throws AlgebraicFormulaSyntaxException

Constructs and returns an AlgebraicTree object.

Returns:

the constructed AlgebraicTree object

Throws:

AlgebraicFormulaSyntaxException - if there is a syntax error in the algebraic formula

add

public boolean add(TreeNode src,
 String subformula)
            throws AlgebraicFormulaSyntaxException

Adds a subformula to the given source tree node.

Parameters:

src - the source tree node to add the subformula to

subformula - the subformula to be added

Returns:

true if the subformula was successfully added, false otherwise

Throws:

AlgebraicFormulaSyntaxException - if there is a syntax error in the subformula
