public writeFrom(notnull buffer as Byte[], offset as Long = 0l, length as Long = -1l) as Void
Writes an existing byte-array range exactly, without copying it first. A zero-byte request performs no native output operation.
| Parameter | Description |
|---|---|
buffer | Source byte array, never null. |
offset | First source index. |
length | Byte count; -1 selects the remainder of the buffer. |
output.writeFrom(buffer, 0l, count)
