readData

protected java.lang.Object readData(Layout index,
                                    DataType dataType)
                             throws java.io.IOException

Read data subset from file for a variable, create primitive array.

Specified by:

readData in class N3iosp

Parameters:

index - handles skipping around in the file.

dataType - dataType of the variable

Returns:

primitive array with data read in

Throws:

java.io.IOException - on error

readData

protected long readData(Layout index,

write data to a file for a variable.

Specified by:

writeData in class N3iosp

Parameters:

values - write this data.

index - handles skipping around in the file.

dataType - dataType of the variable

Throws:

java.io.IOException - on error
