Constructor Detail

HeapFloatVector

public HeapFloatVector(int len)

Don't use this except for testing purposes.

Parameters:

len - the number of rows

Method Detail

getFloat

public float getFloat(int i)

Specified by:

getFloat in interface FloatColumnVector

setFloat

public void setFloat(int i,
                     float value)

Description copied from interface: WritableFloatVector

Set float at rowId with the provided value.

Specified by:

setFloat in interface WritableFloatVector

setFloatsFromBinary

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

Description copied from interface: WritableFloatVector

Set floats from binary, need use UNSAFE to copy.

Specified by:

setFloatsFromBinary in interface WritableFloatVector

Parameters:

rowId - set start rowId.

count - count for float, so the bytes size is count * 4.

src - source binary.

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

fill

public void fill(float value)

Description copied from interface: WritableFloatVector

Fill the column vector with the provided value.

Specified by:

fill in interface WritableFloatVector
