Method Detail

read

public static ResultSet read(java.lang.String urlOrFilename)

Read from a URL (including filenames) and produce a ResultSet. Note that returned result set may stream and so the input stream be read while the ResultSet is used.

See ResultSetFactory.copyResults(ResultSet) for a ResultSet that is detached from the InputStream.

Parameters:

urlOrFilename -

Returns:

ResultSet

read

public static ResultSet read(java.lang.String urlOrFilename,
                             Lang lang)

Read from a URL (including filenames) and produce a ResultSet; the stream is expect to use syntax lang. Note that returned result set may stream and so the input stream be read while the ResultSet is used. See ResultSetFactory.copyResults(ResultSet) for a ResultSet that is detached from the InputStream.

Parameters:

urlOrFilename -

lang -

Returns:

ResultSet

read

public static ResultSet read(java.io.InputStream input)

Parameters:

input -

Returns:

ResultSet

read

public static ResultSet read(java.io.InputStream input,
