setBigInt method
Writes a big signed integer to a region of the buffer.
The value is written to the range [offset : offset+length]. If length is omitted, the
minimum number of bytes required to store this big integer value is used.
The range must satisy the relations 0 ≤ offset ≤ offset+length ≤ this.length.
Implementation
void setBigInt(final BigInt value, final int length) {
_increaseCapacity(length);
offset = buffer.setBigInt(value, offset, length);
}
