public class SPCReader
extends FormatReader

SPCReader is the file format reader for Becker & Hickl SPC-Image SPC FIFO files.

Author:

Ian i.munro at imperial.ac.uk Ported from Matlab code kindly provided by ulorenzo at ikasle.ehu.eus. This format is documented in the TCSPC Handbook available from http://www.becker-hickl.com/handbookphp.htm See Page 675 FIFO Data Files (SPC-134, SPC-144, SPC-154, SPC-830). Note that this code assumes the presence of pixel clock events and therefore the MacroTime information is not used.

Method Detail

isSingleFile

public boolean isSingleFile(java.lang.String id)
                     throws FormatException,
                            java.io.IOException

Description copied from interface: IFormatReader

Returns true if this is a single-file format.

Specified by:

isSingleFile in interface IFormatReader

Overrides:

isSingleFile in class FormatReader

Throws:

FormatException

java.io.IOException

fileGroupOption

public int fileGroupOption(java.lang.String id)
                    throws FormatException,
                           java.io.IOException

Description copied from interface: IFormatReader

Returns an int indicating that we cannot, must, or might group the files in a given dataset.

Specified by:

fileGroupOption in interface IFormatReader

Overrides:

fileGroupOption in class FormatReader

Throws:

FormatException

java.io.IOException

isThisType

public boolean isThisType(java.lang.String name,
                          boolean open)

Description copied from class: FormatReader

Checks if a file matches the type of this format reader. Checks filename suffixes against those known for this format. If the suffix check is inconclusive and the open parameter is true, the file is opened and tested with FormatReader.isThisType(RandomAccessInputStream).

Specified by:

isThisType in interface IFormatReader

Overrides:

isThisType in class FormatReader

open - If true, and the file extension is insufficient to determine the file type, the (existing) file is opened for further analysis.

getSeriesUsedFiles

public java.lang.String[] getSeriesUsedFiles(boolean noPixels)

Description copied from interface: IFormatReader

Returns an array of filenames needed to open the current series. If the 'noPixels' flag is set, then only files that do not contain pixel data will be returned.

Specified by:

getSeriesUsedFiles in interface IFormatReader

Overrides:

getSeriesUsedFiles in class FormatReader

reopenFile

public void reopenFile()
                throws java.io.IOException

Description copied from interface: IFormatReader

Reopen any files that were closed, and which are expected to be open while the reader is open. This assumes that IFormatHandler.setId(java.lang.String) has been called, but close(false) has not been called.

Specified by:

reopenFile in interface IFormatReader

Overrides:

reopenFile in class FormatReader

Throws:

java.io.IOException

openBytes

public byte[] openBytes(int no,
                        byte[] buf,
                        int x,
                        int y,
                        int w,
                        int h)
                 throws FormatException,
                        java.io.IOException

Description copied from interface: IFormatReader

Obtains a sub-image of the specified image plane into a pre-allocated byte array.

Specified by:

openBytes in interface IFormatReader

Specified by:

openBytes in class FormatReader

Parameters:

no - the image index within the file.

buf - a pre-allocated buffer.

x - X coordinate of the upper-left corner of the sub-image

y - Y coordinate of the upper-left corner of the sub-image

w - width of the sub-image

h - height of the sub-image

Returns:

the pre-allocated buffer buf for convenience.

Throws:

FormatException - if there was a problem parsing the metadata of the file.

java.io.IOException - if there was a problem reading the file.

See Also:

IFormatReader.openBytes(int, byte[], int, int, int, int)

close

public void close(boolean fileOnly)
           throws java.io.IOException

Description copied from interface: IFormatReader

Closes the currently open file. If the flag is set, this is all that happens; if unset, it is equivalent to calling Closeable.close().

Specified by:

close in interface IFormatReader

Overrides:

close in class FormatReader

Throws:

java.io.IOException

initFile

protected void initFile(java.lang.String id)
                 throws FormatException,
                        java.io.IOException

Description copied from class: FormatReader

Initializes the given file (parsing header information, etc.). Most subclasses should override this method to perform initialization operations such as parsing metadata.

Overrides:

initFile in class FormatReader

Throws:

FormatException - if a parsing error occurs processing the file.

java.io.IOException - if an I/O error occurs processing the file

processBuffer

private void processBuffer(int noOfBytes)

invalidAndMark

invalidAndMarkInit

private void invalidAndMarkInit(int blockPtr)

photon

private void photon(int blockPtr)
