Constructor Detail

HeapLongVector

public HeapLongVector(int len)

Don't use this except for testing purposes.

Parameters:

len - the number of rows

Method Detail

getLong

public long getLong(int i)

Specified by:

getLong in interface LongColumnVector

setLong

public void setLong(int i,
                    long value)

Description copied from interface: WritableLongVector

Set long at rowId with the provided value.

Specified by:

setLong in interface WritableLongVector

setLongsFromBinary

public void setLongsFromBinary(int rowId,
                               int count,
                               byte[] src,
                               int srcIndex)

Description copied from interface: WritableLongVector

Set longs from binary, need use UNSAFE to copy.

Specified by:

setLongsFromBinary in interface WritableLongVector

Parameters:

rowId - set start rowId.

count - count for long, so the bytes size is count * 8.

src - source binary.

srcIndex - source binary index, it is the index for byte index.

fill

public void fill(long value)

Description copied from interface: WritableLongVector

Fill the column vector with the provided value.

Specified by:

fill in interface WritableLongVector
