toCharArray

toCharArray(X)

X a scalar/vector of the STRING/BLOB/SYMBOL data type.

Split a string into a vector of the CHAR data type.

• If X is a scalar, return a vector.

• If X is a vector, return an array vector.

str = "It is great!\n"
print str.toCharArray()
// output
['I','t',' ','i','s',' ','g','r','e','a','t','!',10]

str1 = ["A#", "B C", "D\t"]
print str1.toCharArray()
// output
[['A','#'],['B',' ','C'],['D',9]]

//Compress a vector and save it in a binary file
x=1..100
//A string of BLOB type uses the first 4 bytes to identify its length
y=blob(compress(x).concat())
dir = WORK_DIR+"/toCharArray.bin"
g = file(dir, "w")
//Use toCharArray to convert a string of BLOB type, only the correct data will be written to the file (except for the header)
g.write(y.toCharArray())   //467 bytes were written
g.close()

// output
dir1 = WORK_DIR+"/toCharArray1.bin"
g1 = file(dir1, "w")
g1.write(y)    //471 bytes were written
g1.close()
