Parameters:
| Name | Type | Description |
|---|---|---|
value |
Buffer | The buffer to copy. |
offset |
number | The offset in the buffer to start copying into. |
- Source:
Returns:
The new offset which is offset + value.length.
- Type
- number
copyFromBack(value, offsetFromBack)
First call ensureLengthFromBack to make sure the bytearray has
offsetFromBack bytes, then copy value into the array starting
offsetFromBack bytes from the back of the array.
Parameters:
| Name | Type | Description |
|---|---|---|
value |
Buffer | The buffer to copy. |
offsetFromBack |
number | The offset from the back of the array to start copying. |
- Source:
ensureLength(length)
Ensure that this.array has the length, reallocate and copy if necessary.
Update the length of this.array which may be greater than length.
Parameters:
| Name | Type | Description |
|---|---|---|
length |
number | The minimum length for the array. |
- Source:
ensureLengthFromBack(length)
Ensure that this.array has the length. If necessary, reallocate the array
and shift existing data to the back of the new array.
Update the length of this.array which may be greater than length.
Parameters:
| Name | Type | Description |
|---|---|---|
length |
number | The minimum length for the array. |
- Source:
slice(begin, end) → {Buffer}
Return this.array.slice(begin, end);
Parameters:
| Name | Type | Description |
|---|---|---|
begin |
number | The begin index for the slice. |
end |
number | (optional) The end index for the slice. |
