Method Detail

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 StandardListProcessor

Parameters:

jep - the current Jep instance

getLightWeightInstance

public JepComponent getLightWeightInstance()

Description copied from interface: JepComponent

Gets a light-weight instance suitable for using in multiple threads.

Specified by:

getLightWeightInstance in interface JepComponent

Overrides:

getLightWeightInstance in class StandardListProcessor

Returns:

either an new instance, null or 'this'.

fromArgs

public java.lang.Iterable<java.lang.Object> fromArgs(java.lang.Object arg)
                                              throws EvaluationException

Returns an Iterable over the input arguments.

Specified by:

fromArgs in interface ListProcessor

Overrides:

fromArgs in class StandardListProcessor

Parameters:

arg - an input to the function. Expects an argument of type VectorI or MatrixI.

Returns:

a MatrixListProcessor.VectorIterable or MatrixListProcessor.MatrixIterable

Throws:

EvaluationException - if argument is not of type VectorI or MatrixI

getList

public java.util.List<java.lang.Object> getList()

Description copied from interface: ListProcessor

Get an empty list which elements can be added.

Specified by:

getList in interface ListProcessor

Overrides:

getList in class StandardListProcessor

Returns:

an empty list

fromList

public java.lang.Object fromList(java.util.List<java.lang.Object> list)
                          throws EvaluationException

Description copied from interface: ListProcessor

Convert a list produced by ListProcessor.getList() to the type used by Jep environment. Some implementations just return the input.

Specified by:

fromList in interface ListProcessor

Overrides:

fromList in class StandardListProcessor

Parameters:

list - a list

Returns:

a type suitable for use by Jep.

Throws:

EvaluationException - on error

fromCollection

public java.lang.Object fromCollection(java.util.Collection<java.lang.Object> tree)
                                throws EvaluationException

Description copied from interface: ListProcessor

Convert a general collection into a type used the the Jep environment.

Specified by:

fromCollection in interface ListProcessor

Overrides:

fromCollection in class StandardListProcessor

Parameters:

tree - input collection

Returns:

a type suitable for use by Jep

Throws:

EvaluationException - on error
