Method Detail

map

public void map(Chunk[] chks)

Description copied from class: MRTask2

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 MRTask2<ASTddply.ddplyPass1>

reduce

public void reduce(ASTddply.ddplyPass1 p1)

Description copied from class: MRTask2

Override to combine results from 'mrt' into 'this' MRTask2. 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 MRTask2<ASTddply.ddplyPass1>

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

closeLocal

public void closeLocal()

Description copied from class: MRTask2

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 MRTask2<ASTddply.ddplyPass1>

write

public AutoBuffer write(AutoBuffer ab)

Description copied from interface: Freezable

Serialize the 'this' object into the AutoBuffer, returning the AutoBuffer.

Specified by:

write in interface Freezable

Overrides:

write in class DTask

read

public ASTddply.ddplyPass1 read(AutoBuffer ab)

Description copied from interface: Freezable

Deserialize from the AutoBuffer into a pre-existing 'this' object.

Specified by:

read in interface Freezable

Overrides:

read in class DTask

copyOver

public void copyOver(Freezable dt)

Overrides:

copyOver in class DTask
