Method Details

setAutoFlush

public void setAutoFlush(boolean autoFlush)

Description copied from interface: ExpressionDataMatrixWriter

Flush every time a complete line is written.

This is not very efficient, but it can be used to view the output of a matrix as it is being written.

Specified by:

setAutoFlush in interface ExpressionDataMatrixWriter<BulkExpressionDataMatrix<?>,BulkExpressionDataVector>

setScaleType

public void setScaleType(@Nullable
 ScaleType scaleType)

Description copied from interface: ExpressionDataMatrixWriter

Set the scale type to use when writing the matrix.

When null, the original values must be used.

Specified by:

setScaleType in interface ExpressionDataMatrixWriter<BulkExpressionDataMatrix<?>,BulkExpressionDataVector>

write

public int write(BulkExpressionDataMatrix<?> matrix,
 Class<? extends BulkExpressionDataVector> vectorType,
 Writer writer)
          throws IOException,
UnsupportedOperationException

Description copied from interface: ExpressionDataMatrixWriter

Write the matrix to the given writer.

Specified by:

write in interface ExpressionDataMatrixWriter<BulkExpressionDataMatrix<?>,BulkExpressionDataVector>

Parameters:

vectorType - the type of vectors to write. This helps the writer determine how the QuantitationType of the matrix should be interpreted.

Returns:

the number of vectors written

Throws:

UnsupportedOperationException - if the matrix cannot be written to a text output (i.e. if this is a binary format).

IOException
