Method Detail

atd_impl

protected double atd_impl(int idx)

Description copied from class: Chunk

Chunk-specific readers. Not a public API

at8_impl

protected long at8_impl(int idx)

isNA_impl

protected boolean isNA_impl(int idx)

inflate_impl

public NewChunk inflate_impl(NewChunk nc)

Description copied from class: Chunk

Chunk-specific bulk inflater back to NewChunk. Used when writing into a chunk and written value is out-of-range for an update-in-place operation. Bulk copy from the compressed form into the nc._ls array.

Specified by:

inflate_impl in class Chunk

write_impl

public AutoBuffer write_impl(AutoBuffer bb)

Description copied from class: Chunk

Custom serializers implemented by Chunk subclasses: the _mem field contains ALL the fields already.

Specified by:

write_impl in interface Freezable

Overrides:

write_impl in class Chunk

Parameters:

bb - AutoBuffer to write this object to.

Returns:

Returns the original AutoBuffer for flow-coding.

read_impl

public SubsetChunk read_impl(AutoBuffer bb)

Description copied from class: Chunk

Custom deserializers, implemented by Chunk subclasses: the _mem field contains ALL the fields already. Init _start to -1, so we know we have not filled in other fields. Leave _vec and _chk2 null, leave _len unknown.

Specified by:

read_impl in interface Freezable

Specified by:

read_impl in class Chunk

Parameters:

bb - AutoBuffer to read this object from.

Returns:

Returns a new instance of object reconstructed from AutoBuffer.
