Field Detail

current

public FormulaTreeStructure current

The current insertion position in the formula (tree structure).

Constructor Detail

Formula

public Formula()

The Constructor.

Method Detail

isOperator

public boolean isOperator()

To check is the instance is an operator.

Specified by:

isOperator in class FormulaTreeStructure

Returns:

true if it is an operator. false otherwise.

insert

public FormulaTreeStructure insert(FormulaTreeStructure current)

Inserts the operator instance in the formula tree, from the current insertion position. (checks the priorities and goes up in the tree if necessary).
At the moment, we can't insert a formula in an another formula.

Specified by:

insert in class FormulaTreeStructure

Parameters:

current - the current insertion position.

Returns:

the new insertion position.

createLinear

public java.lang.String createLinear(java.lang.String linear)

The Creation of the corresponding linear expression of the formula.

Specified by:

createLinear in class FormulaTreeStructure

clear

public void clear()

clears the formula.

getLinear

public java.lang.String getLinear()

Returns the linear expression of the formula.

getOpenMath

public java.lang.String getOpenMath()

Returns the OpenMath representation of the formula.

getMathML

public java.lang.String getMathML()

Returns the MathML representation of the formula.

getPMML

public java.lang.String getPMML()

evaluate

public java.lang.String evaluate()

Evaluates the instance.

Specified by:

evaluate in class FormulaTreeStructure

consumeLinearParserEvent

public void consumeLinearParserEvent(LinearParserEvent linearParserEvent)

Treats the event received.

Specified by:

consumeLinearParserEvent in interface LinearParserListener

Parameters:

linearParserEvent - the event received.

setDoProcessing

public void setDoProcessing(boolean doProcessing)

Sets if we had to process the instance before rendering.

Parameters:

doProcessing - true if the instance needs a processing. false otherwise.

getDoProcessing

public boolean getDoProcessing()

Returns true if the instance needs a processing. false otherwise.

setProcessor

public void setProcessor(Processor processor)

Sets the processor of the instance.

Parameters:

processor - the processor.

getProcessor

public Processor getProcessor()

Returns the processor of the instance.

doProcess

public void doProcess()

Processes the instance

main

public static void main(java.lang.String[] args)
