Method Detail

map

public void map(Chunk[] chks)

Description copied from class: MRTask

Override with your map implementation. This overload is given an array of local input Chunks, for Frames with arbitrary column numbers. All map variants are called, but only one is expected to be overridden.

Overrides:

map in class MRTask<ASTddply.ddplyPass1>

reduce

public void reduce(ASTddply.ddplyPass1 p1)

Description copied from class: MRTask

Override to combine results from 'mrt' into 'this' MRTask. Both 'this' and 'mrt' are guaranteed to either have map() run on them, or be the results of a prior reduce(). Reduce is optional if, e.g., the result is some output vector.

Overrides:

reduce in class MRTask<ASTddply.ddplyPass1>

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

closeLocal

public void closeLocal()

Description copied from class: MRTask

Override to do any remote cleaning on the last remote instance of this object, for disposing of node-local shared data structures.

Overrides:

closeLocal in class MRTask<ASTddply.ddplyPass1>

write_impl

public AutoBuffer write_impl(AutoBuffer ab)

Description copied from interface: Freezable

Implementation of the Iced serialization protocol, only called by auto-genned code. Not intended to be called by user code. Override only for custom Iced serializers.

Specified by:

write_impl in interface Freezable

Overrides:

write_impl in class H2O.H2OCountedCompleter<ASTddply.ddplyPass1>

Parameters:

ab - AutoBuffer to write this object to.

Returns:

Returns the original AutoBuffer for flow-coding.

read_impl

public ASTddply.ddplyPass1 read_impl(AutoBuffer ab)

Description copied from interface: Freezable

Implementation of the Iced serialization protocol, only called by auto-genned code. Not intended to be called by user code. Override only for custom Iced serializers.

Specified by:

read_impl in interface Freezable

Overrides:

read_impl in class H2O.H2OCountedCompleter<ASTddply.ddplyPass1>

Parameters:

ab - AutoBuffer to read this object from.

Returns:

Returns a new instance of object reconstructed from AutoBuffer.
