toCharArray

Syntax

toCharArray(X)

Arguments

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

Details

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.

Examples

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

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

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