Package ubic.gemma.core.datastructure.matrix

Class EmptyExpressionMatrix

java.lang.Object

ubic.gemma.core.datastructure.matrix.BaseExpressionDataMatrix<Object>

ubic.gemma.core.datastructure.matrix.EmptyExpressionMatrix

All Implemented Interfaces:

Serializable, BulkExpressionDataMatrix<Object>, ExpressionDataMatrix<Object>

public class EmptyExpressionMatrix
extends BaseExpressionDataMatrix<Object>

Used to make a 'dummy matrix' that has the column information populated. This is useful for processing where we want the sample information organized,but not the data. Data access operations are not supported.

Method Detail

columns

public int columns()

Description copied from interface: ExpressionDataMatrix

Obtain the total number of columns.

get

public Object get(CompositeSequence designElement,
                  BioAssay bioAssay)

Description copied from interface: BulkExpressionDataMatrix

Access a single value of the matrix. Note that because there can be multiple bioassays per column and multiple designelements per row, it is possible for this method to retrieve a data that does not come from the bioassay and/or designelement arguments.

Parameters:

designElement - de

bioAssay - ba

Returns:

T t

get

public Object get(int row,
                  int column)

Description copied from interface: ExpressionDataMatrix

Access a single value of the matrix by row and column.

get

public Object[][] get(List<CompositeSequence> designElements,
                      List<BioAssay> bioAssays)

Description copied from interface: BulkExpressionDataMatrix

Access a submatrix

Parameters:

designElements - de

bioAssays - bas

Returns:

T[][]

getColumn

public Object[] getColumn(BioAssay bioAssay)

Description copied from interface: BulkExpressionDataMatrix

Access a single column of the matrix.

Parameters:

bioAssay - i

Returns:

T[]

getColumn

public Object[] getColumn(int column)

Description copied from interface: ExpressionDataMatrix

Access a single column of the matrix.

Parameters:

column - index

Returns:

T[]

getColumns

public Object[][] getColumns(List<BioAssay> bioAssays)

Description copied from interface: BulkExpressionDataMatrix

Access a submatrix slice by columns

Parameters:

bioAssays - ba

Returns:

t[][]

getRawMatrix

public Object[][] getRawMatrix()

Description copied from interface: BulkExpressionDataMatrix

Access the entire matrix.

Returns:

T[][]

getRow

public Object[] getRow(CompositeSequence designElement)

Description copied from interface: ExpressionDataMatrix

Return a row that 'came from' the given design element.

Parameters:

designElement - de

Returns:

the corresponding row or null if the design element is not found in the matrix

getRow

public Object[] getRow(int index)

Description copied from interface: ExpressionDataMatrix

Access a single row of the matrix, by index. A complete row is returned.

Parameters:

index - i

Returns:

t[]

hasMissingValues

public boolean hasMissingValues()

Returns:

true if any values are null or NaN (for Doubles); all other values are considered non-missing.

rows

public int rows()

Returns:

int

set

public void set(int row,
                int column,
                Object value)

Description copied from interface: BulkExpressionDataMatrix

Set a value in the matrix, by index

Parameters:

row - row

column - col

value - val

vectorsToMatrix

protected void vectorsToMatrix(Collection<? extends BulkExpressionDataVector> vectors)
