Buffer
Operators and functions for working with an array of bytes (buf type) are described here.
Operator | Result | Description |
* buf | int | Returns the number of bytes in the array. |
buf + buf | buf | Merges two buffers. |
buf = buf | buf | Assignment operator. |
buf &= buf | buf | Create a clone of the buffer. The new variable will work with the same data set. |
buf += buf | buf | Appends a buffer to a buffer variable. |
buf += int | buf | Appends one byte to the buffer. The number must be less than 256. |
buf += str | buf | Appends a string to the buffer. |
buf += char | buf | Appends a character to the buffer. |
buf [ int ] | int | Sets/gets a byte by index. |
The buf function converts a string to a buf value and returns it.
The str function converts a buf value to a string and returns it.
The Base64 function converts a value of the buf type into a string in base64 encoding and returns it.
The Del function removes part of the data from the byte array. off is the offset of the data to be deleted, length is the number of bytes to be deleted. If length is less than zero, then the data will be deleted to the left of the specified offset. The function returns the b variable in which the deletion occurred.
The Hex function encodes a buf value to a hexadecimal string and returns it.
The Insert function inserts an array of bytes src into the array b. off is the offset where the specified byte array will be inserted. The function returns the variable b.
The UnBase64 function converts a string in base64 encoding into a value of the buf type and returns it.
The UnHex function returns the buf value represented by the hexadecimal string s. The input string must contain only hexadecimal characters.
