com.singularsys.extensions.matrix.genericmat.GenericMatrixFactory<Object>

com.singularsys.extensions.matrix.objectmat.ObjectMatrixFactory

All Implemented Interfaces:

MatrixFactoryI, JepComponent, Serializable

public class ObjectMatrixFactory
extends GenericMatrixFactory<Object>

An implementation of vectors and matrices where elements are Objects. To set up use

    MatrixFactoryI mfac = new ObjectMatrixFactory();
    MatrixFieldI mf = new SimpleMatrixField(mfac);
    MatrixOperatorTable opTab = new MatrixOperatorTable(mfac, mf);
    MatrixFunctionTable mftab = new MatrixFunctionTable(mfac, mf);
    jep = new Jep(opTab,mftab);

Method Details

buildDataArray

public Object[][] buildDataArray(int rows,
 int cols)

Description copied from class: GenericMatrixFactory

Build a data array. A typical concrete implementation will just use return new E[rows][cols].

Overrides:

buildDataArray in class GenericMatrixFactory<Object>

Parameters:

rows - number of rows

cols - number of cols

Returns:

the array.

buildDataArray

public Object[] buildDataArray(int len)

Description copied from class: GenericMatrixFactory

Build a data array. A typical concrete implementation will just use return new E[rows][len].

Overrides:

buildDataArray in class GenericMatrixFactory<Object>

Parameters:

len - number of elements

Returns:

the array.

elementValue

public Object elementValue(Object o)

Description copied from class: GenericMatrixFactory

Convert the element o to type E. A typical implementation will just use

 public abstract E elementValue(Object o) {
     if(o instanceof E)
         return (E) o;
     return null;
 }

Specified by:

elementValue in interface MatrixFactoryI

Overrides:

elementValue in class GenericMatrixFactory<Object>

Parameters:

o - value to convert

Returns:

the value cast to type E or null if the type cannot be converted.

cast

public ObjectMatrix cast(MatrixI m)

Description copied from class: GenericMatrixFactory

A typical implementation will just use return (GenericMatrix<E>) m;

Overrides:

cast in class GenericMatrixFactory<Object>

Parameters:

m - the matrix to cast

Returns:

a matrix of type GenericMatrix<E> = GenericMatrix<E>

cast

public ObjectVector cast(VectorI v)

Description copied from class: GenericMatrixFactory

A typical implementation will just use return (V) v;

Overrides:

cast in class GenericMatrixFactory<Object>

Parameters:

v - the vector to cast

Returns:

a vector of type V = GenericVector<E>

newMatrixUnchecked

public ObjectMatrix newMatrixUnchecked(Object[][] data)

Overrides:

newMatrixUnchecked in class GenericMatrixFactory<Object>

newVectorUnchecked

public ObjectVector newVectorUnchecked(Object[] data)

Overrides:

newVectorUnchecked in class GenericMatrixFactory<Object>

getLightWeightInstance

public JepComponent getLightWeightInstance()

Returns this

Specified by:

getLightWeightInstance in interface JepComponent

Overrides:

getLightWeightInstance in class GenericMatrixFactory<Object>

Returns:

either a new instance, null or 'this'.
