Parameters
| Parameter | Type | Description |
|---|---|---|
|
| Whether the number is little-endian |
Returns
number
Read value
Throws
RangeError if the buffer is out of bounds
Defined in
readFloat64()
readFloat64(
littleEndian:boolean):number
Reads a 64-bit floating point number from the buffer.
Parameters
| Parameter | Type | Description |
|---|---|---|
|
| Whether the number is little-endian |
Returns
number
Read value
Throws
RangeError if the buffer is out of bounds
Defined in
readBytes()
readBytes(
byteLength:number):Uint8Array
Reads a set of bytes from the buffer.
Parameters
| Parameter | Type |
|---|---|
|
|
Returns
An Uint8Array containing the read bytes
Throws
RangeError if the buffer is out of bounds
Defined in
readBytesUnsafe()
readBytesUnsafe(
byteLength:number):Uint8Array
Reads a set of bytes from the buffer without copying.
Parameters
| Parameter | Type |
|---|---|
|
|
Returns
An Uint8Array containing the read bytes
Throws
RangeError if the buffer is out of bounds
Remarks
The returned Uint8Array shares the same memory as the buffer. Use with caution, as modifying the Uint8Array will also modify the buffer.
Defined in
subarray()
subarray(

Returns a subarray of the buffer.
Parameters
| Parameter | Type | Description |
|---|---|---|
|
| The start offset in bytes |
|
| The end offset in bytes |
Returns
The subarray
Remarks
The returned Uint8Array shares the same memory as the buffer.
