# S4 method for ANY
asList(object, ...)

# S4 method for CWL
asList(object, ...)

# S4 method for SingleEnum
asList(object, ...)

# S4 method for SimpleList
asList(object, ...)

# S4 method for DSCList
asList(object, ...)

Arguments

object	object, could be S4/R5 object. For example, class CWL, SimpleList.
...	other parameters passed to as.yaml or toJSON.

Value

a list object or json or yaml file.

Examples

# define a S4 object
A <- setClass("A", slots = list(a = "character", b = "numeric"))
# define a reference object which extends 'CWL' class
B <- setRefClass("B", fields = list(x = "character", y = "A"), contains = "CWL")
# new instances
a <- A(a = "hello", b = 123)
b <- B(x = "world", y = a)

# show
b
#> x: world
#> 'y':
#>   a: hello
#>   b: 123.0
#> 
b$show("JSON")
#> {
#>     "x": "world",
#>     "y": {
#>         "a": "hello",
#>         "b": 123
#>     }
#> }
#>  
b$show("YAML")
#> x: world
#> 'y':
#>   a: hello
#>   b: 123.0
#> 

# You can convert slots/fields into a list
asList(a)
#> $a
#> [1] "hello"
#> 
#> $b
#> [1] 123
#> 
asList(b)
#> $x
#> [x] "world"
#> 
#> $y
#> $y$a
#> [x] "hello"
#> 
#> $y$b
#> [x] 123
#> 
#> 
b$toList()
#> $x
#> [x] "world"
#> 
#> $y
#> $y$a
#> [x] "hello"
#> 
#> $y$b
#> [x] 123
#> 
#> 
b$toYAML()
#> [1] "x: world\n'y':\n  a: hello\n  b: 123.0\n"
b$toJSON()
#> {"x":"world","y":{"a":"hello","b":123}}
