Constructor Detail

Constructs a new ICSReader.

Method Detail

isSingleFile

public boolean isSingleFile(String id)
                     throws FormatException,
                            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

IOException

getDomains

public String[] getDomains()

Description copied from interface: IFormatReader

Returns the list of domains represented by the current file.

Specified by:

getDomains in interface IFormatReader

Overrides:

getDomains in class FormatReader

isInterleaved

public boolean isInterleaved(int subC)

Description copied from interface: IFormatReader

Gets whether or not the given sub-channel is interleaved. This method exists because some data with multiple rasterized sub-dimensions within C have one sub-dimension interleaved, and the other not—e.g., SDTReader handles spectral-lifetime data with interleaved lifetime bins and non-interleaved spectral channels.

Specified by:

isInterleaved in interface IFormatReader

Overrides:

isInterleaved in class FormatReader

fileGroupOption

public int fileGroupOption(String id)
                    throws FormatException,
                           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

IOException

openBytes

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

IOException - if there was a problem reading the file.

See Also:

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

getSeriesUsedFiles

public 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

close

public void close(boolean fileOnly)
           throws 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:

IOException

reopenFile

public void reopenFile()
                throws 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:

IOException

initFile

protected void initFile(String id)
                 throws FormatException,
                        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.

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

                       int stop)

findKeyValueForCategory

                    String[] regexes,
                    int regexesIndex)

private boolean checkUnit(String actual,
                String... expected)

Verifies that a unit matches the expected value.
