Method Details

add

public void add(DATA_TYPE value)

Description copied from interface: AppendableColumn

Append a DATA_TYPE to this column.

Specified by:

add in interface AppendableColumn<DATA_TYPE>

Overrides:

add in class BaseAppendableColumn<DATA_TYPE>

Parameters:

value - The value to append

addComputed

public final void addComputed(int count,
 @NotNull
 LocalAppendableColumn.ValueSupplier<DATA_TYPE> valueSupplier)
                       throws IOException

Description copied from class: LocalAppendableColumn

Add values computed on demand from a function over an int value index. Note that this is generally sub-optimal for columns of primitive types.

Overrides:

addComputed in class LocalAppendableColumn<DATA_TYPE>

Parameters:

count - The number of values to add

valueSupplier - The value supplier, over domain [0, length)

Throws:

IOException

toBytes

protected abstract ByteBuffer toBytes(@NotNull
 DATA_TYPE value,
 @NotNull
 ByteBuffer outputBuffer)

Convert value to bytes in a ByteBuffer.

Parameters:

value - The value to convert

outputBuffer - The initial output buffer

Returns:

The (possibly new and larger) output buffer, positioned for reading
