Method Detail

isSingleFile

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

Description copied from interface: IFormatReader

Returns true if the named file is expected to be the only file in the dataset. For single-file formats, always returns true.

Specified by:

isSingleFile in interface IFormatReader

Overrides:

isSingleFile in class FormatReader

Throws:

FormatException

java.io.IOException

getDomains

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

Description copied from interface: IFormatReader

Returns an indication of whether the files in a multi-file dataset can be handled individually. This method is only useful for formats and datasets which contain multiple files.

Specified by:

fileGroupOption in interface IFormatReader

Overrides:

fileGroupOption in class FormatReader

Parameters:

id - a file in the multi-file dataset

Returns:

an int indicating that we cannot, must, or might group the files. A return value of FormatTools.MUST_GROUP indicates that the files cannot be handled separately; the reader will always detect and read all files in the dataset. FormatTools.CAN_GROUP indicates that the files may be handled separately, but file grouping must then be disabled via IFormatReader.setGroupFiles(boolean). FormatTools.CANNOT_GROUP indicates that the files must be handled separately; the reader will not attempt to read all files in the dataset (this is rare).

Throws:

FormatException

java.io.IOException

See Also:

FormatTools.MUST_GROUP, FormatTools.CAN_GROUP, FormatTools.CANNOT_GROUP

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 plane index within the current series.

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)

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. The first element in the array is expected to be the path passed to IFormatHandler.setId(String), if appropriate based upon 'noPixels'. The remaining elements are expected to be in a consistent order; if a directory listing is necessary to build the list then it should be sorted first.

Specified by:

getSeriesUsedFiles in interface IFormatReader

Overrides:

getSeriesUsedFiles in class FormatReader

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

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

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

tokenize

private java.lang.String[] tokenize(java.lang.String line)

findKeyValue

java.lang.String[] findKeyValue(java.lang.String[] tokens,

private java.lang.String concatenateTokens(java.lang.String[] tokens,
                                           int start,
                                           int stop)

findKeyValueForCategory

private java.lang.String[] findKeyValueForCategory(java.lang.String[] tokens,
                                                   java.lang.String[][] regexesArray)

findKeyValueOther

private java.lang.String[] findKeyValueOther(java.lang.String[] tokens,
                                             java.lang.String[][] regexesArray)

private boolean compareTokens(java.lang.String[] tokens,
                              int tokenIndex,
                              java.lang.String[] regexes,
                              int regexesIndex)

splitDoubles

private java.lang.Double[] splitDoubles(java.lang.String v)

Splits the given string into a list of Doubles.

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