Method Detail

guardedSplit

protected static java.lang.String[] guardedSplit(java.lang.String s,
                                                 char delim,
                                                 char exclude1,
                                                 char exclude2)

only split on the delimiter when we are not within the exclude delimiters. For example, x=getDataSet("http://autoplot.org/data/autoplot.cdf?Magnitude&noDep=T")&y=getDataSet('http://autoplot.org/data/autoplot.cdf?BGSEc&slice1=2')&sqrt(x)

Parameters:

s - the string to split.

delim - the delimiter to split on, for example the ampersand (&).

exclude1 - for example the single quote (')

exclude2 - for example the double quote (") Note URIs don't support these anyway.

Returns:

the split.

getDataSet

public QDataSet getDataSet(ProgressMonitor mon)
                    throws java.lang.Exception

Description copied from interface: DataSource

retrieve the dataset. This allowed to be sub-interactive or batch time scale, and will block until the dataset is produced. This may return null when no data is available, or NoDataInIntervalException can be thrown. If the user cancelled the operation, then java.io.InterrupedIOExcaption or better yet org.das2.CancelledOperationException should be called. These will simply display "cancelled" (or similar) on the status bar.

Specified by:

getDataSet in interface DataSource

Specified by:

getDataSet in class AbstractDataSource

Returns:

the DataSet for the URI, or null if no data is available.

Throws:

java.lang.Exception
