Usage

hash_set_keys(h)

# S3 method for class 'hash_set'
x[[i]]

# S3 method for class 'hash_set'
x[i]

# S3 method for class 'hash_set'
x$name

# S3 method for class 'hash_set'
x[[i]] <- value

# S3 method for class 'hash_set'
x[i] <- value

# S3 method for class 'hash_set'
x$name <- value

# S3 method for class 'hash_set'
length(x)

# S3 method for class 'hash_set'
print(x, ...)

Arguments

h, x

A hash_set object.

i, name

A single or a vector of keys.

value

Values.

...

Other arguments.

Value

  • hash_set_keys() returns a vector of all keys.

  • [[ or $ returns a single logical value.

  • [ returns a vector of logical values.

Details

For the assignment, value should be logical. TRUE means to insert the corresponding keys to the hash set, and FALSE means to delete the corresponding keys.

Examples

h = hash_set(letters)
h$a
#> [1] TRUE
h[c("a", "b")]
#> [1] TRUE TRUE
h$a = FALSE
hash_set_keys(h)
#>  [1] "v" "u" "z" "t" "s" "r" "q" "p" "n" "m" "o" "l" "x" "k" "j" "h" "y" "g" "f"
#> [20] "d" "e" "c" "i" "b" "w"
h$aaaa = TRUE
hash_set_keys(h)
#>  [1] "v"    "u"    "z"    "t"    "s"    "r"    "q"    "p"    "n"    "m"   
#> [11] "o"    "l"    "x"    "k"    "j"    "h"    "y"    "g"    "f"    "d"   
#> [21] "aaaa" "e"    "c"    "i"    "b"    "w"
