List of openTableReader() Examples

Examples of openTableReader()

org.kiji.schema.KijiTable.openTableReader()
Opens a KijiTableReader for this table.
This method is equivalent to getReaderFactory().readerBuilder().build(). It sets all options to their default values.

The caller of this method is responsible for closing the returned reader.

The reader returned by this method does not provide any isolation guarantee. In particular, you should assume that the underlying resources (connections, buffers, etc) are used concurrently for other purposes.
@return A KijiTableReader for this table. @throws KijiIOException Future implementations may throw unchecked KijiIOException.
