com.singularsys.jep.misc.boundvariable.BoundVariableFactory

All Implemented Interfaces:

JepComponent, java.io.Serializable

public class BoundVariableFactory
extends VariableFactory

A variable factory for creating bound variables.

If a variable is called with an VariableBinding as its value then a BoundVariable will be created.

Since:

Modifier and Type	Method	Description
Variable	createVariable(java.lang.String name)	Create a variable with a name but not value Calls VariableFactory.createVariable(String, Object) so subclasses need not override this method.
Variable	createVariable(java.lang.String name, VariableBinding vb)	Creates a variable with the given VariableBinding
Variable	createVariable(java.lang.String name, java.lang.Object value)	If the value is an instance of VariableBinding then call the createVariable(String, VariableBinding) method, otherwise treat as normal.
VariableBindingMapper	getVariableMapping()	Gets the VariableMapping for the creation of new variables.
void	setVariableMapping(VariableBindingMapper vm)	Sets the VariableMapping for the creation of new variables.

BoundVariableFactory

public BoundVariableFactory(VariableBindingMapper vbm)

Create the factory with a specific VariableMapping for creation of new variables.

Parameters:

vbm - the mapping class translates a specific jep varable names to particualr objects

Method Detail

createVariable

public Variable createVariable(java.lang.String name)

Description copied from class: VariableFactory

Create a variable with a name but not value Calls VariableFactory.createVariable(String, Object) so subclasses need not override this method.

Overrides:

createVariable in class VariableFactory

Parameters:

name - name of variable

referece to Variable object

createVariable

public Variable createVariable(java.lang.String name,
                               java.lang.Object value)

If the value is an instance of VariableBinding then call the createVariable(String, VariableBinding) method, otherwise treat as normal.

Overrides:

createVariable in class VariableFactory

Parameters:

name - variable name

value - either the initial value or a VariableBinding object

Returns:

the created variable

createVariable

public Variable createVariable(java.lang.String name,
                               VariableBinding vb)

Creates a variable with the given VariableBinding

Parameters:

name - name of the variable

vb - binding object

Returns:

a new BoundVariable

getVariableMapping

public VariableBindingMapper getVariableMapping()

Gets the VariableMapping for the creation of new variables.

Returns:

the mapping used or null if none set.

setVariableMapping

public void setVariableMapping(VariableBindingMapper vm)

Sets the VariableMapping for the creation of new variables.

Parameters:

vm - the mapping
