Class XOperatorTable

java.lang.Object

com.singularsys.jep.EmptyOperatorTable

com.singularsys.jep.OperatorTable2

com.singularsys.jep.standard.StandardOperatorTable2

com.singularsys.extensions.xjep.XOperatorTable

All Implemented Interfaces:

JepComponent, OperatorTableI, java.io.Serializable

public class XOperatorTable
extends StandardOperatorTable2

An operator table to use in the XJep. As the StandardOperatorTable2 but uses the symbolic assignment function XAssign. The table can be configured in two ways:

• two different assignment operations, one for numerical assignemnt and one for symbilic assignment.
• A single assignment operator which always does symbolic assignment

Since:

Jep 3.5 / Extensions 2.0

protected Operator XAssignNoEqnOp

Constructor Detail

XOperatorTable

public XOperatorTable()

Constructor with a single assignment operator for symbolic assignment

XOperatorTable

public XOperatorTable(java.lang.String xassignSym)

Constructor with two assignment operators, the standard numerical assignment and a new symbolic assignment operator

Parameters:

xassignSym - symbol used for symbolic assignment

XOperatorTable

public XOperatorTable(OperatorTable2 oldTable)

Decorator constructor. Replaces the assignment operator's pfmc with symbolic assignment XAssign

Parameters:

oldTable - existing table whos operators will be copied into this

XOperatorTable

public XOperatorTable(OperatorTable2 oldTable,
                      java.lang.String xassignSym)

Adds a new operator for symbolic assignment in addition to normal assignment.

Parameters:

oldTable - existing table whos operators will be copied into this

xassignSym - symbol used for new assignment operator

Method Detail

setBasicPfmcs

protected void setBasicPfmcs()

Description copied from class: StandardOperatorTable2

Sets the standard set of pfmc's for basic operators. This method is called by the constructor and subclasses can override this method to change or prevent building of these pfmcs.

Overrides:

setBasicPfmcs in class StandardOperatorTable2

See Also:

OperatorTable2.BasicOperators

setSpecialPfmcs

protected void setSpecialPfmcs()

Description copied from class: StandardOperatorTable2

Sets the standard set of pfmc's for special operators assignment, dot product, cross product, list operator and the element of operator. This method is called by the constructor and subclasses can override this method to change or prevent building of these pfmcs.

Overrides:

setSpecialPfmcs in class StandardOperatorTable2

See Also:

OperatorTable2.SpecialOperators

setPsudoPfmcs

protected void setPsudoPfmcs()

Overrides:

setPsudoPfmcs in class StandardOperatorTable2

init

public void init(Jep jep)

Description copied from interface: JepComponent

Initialize the component. This methods is called whenever a component is added to Jep. Hence it allows components to keep track of the other components they may rely on.

Specified by:

init in interface JepComponent

Overrides:

init in class EmptyOperatorTable

Parameters:

jep - the current Jep instance

setXPfmcs

protected void setXPfmcs()

getXAssign

public Operator getXAssign()
