	bool memoryOnly
)

Protected Function GetInputReader ( 
	partition As Integer,
	index As Integer,
	memoryOnly As Boolean
) As IRecordReader

protected:
IRecordReader^ GetInputReader(
	int partition, 
	int index, 
	bool memoryOnly
)

member GetInputReader : 
        partition : int * 
        index : int * 
        memoryOnly : bool -> IRecordReader 

Parameters

partition  Int32

The partition of the reader to return.

index  Int32

The index of the record reader to return.

memoryOnly  Boolean

to return only inputs that are stored in memory; otherwise, .

Return Value

Because the MultiInputRecordReaderT tries to keep the inputs that in memory in front of the inputs that aren't, if a call to GetInputReader(Int32, Int32, Boolean) returned , subsequent calls with the same partition and index might not return .

Once a call to GetInputReader(Int32, Int32, Boolean) has returned a value other than , subsequent calls with the same partition and index are guaranteed to return the same value.

Two calls to GetInputReader(Int32, Int32, Boolean) with the same index but a different partition aren't guaranteed to return inputs from the same source.
