readImpl

protected Record readImpl()
                   throws Throwable

Description copied from class: DataReader

Overridden by subclasses to read the next record from this DataReader. The default implementation of DataReader.read() now insures that this method will not be called again after it returns a null.

If no record is available, null will be returned.

Specified by:

readImpl in class DataReader

Throws:

Throwable

available

public int available()

Description copied from class: DataReader

Returns the number of records that can probably be read without blocking.

Overrides:
