to_a()
public
Returns an Array with 14 elements representing the instruction sequence with the following data:
- magic
-
A string identifying the data format. Always YARVInstructionSequence/SimpleDataFormat.
- major_version
-
The major version of the instruction sequence.
- minor_version
-
The minor version of the instruction sequence.
- format_type
-
A number identifying the data format. Always 1.
- misc
-
A hash containing:
- :arg_size
-
the total number of arguments taken by the method or the block (0 if iseq doesn’t represent a method or block)
- :local_size
-
the number of local variables + 1
- :stack_max
-
used in calculating the stack depth at which a SystemStackError is thrown.
- #label
-
The name of the context (block, method, class, module, etc.) that this instruction sequence belongs to.
<main> if it’s at the top level, <compiled> if it was evaluated from a string.
- #path
-
The relative path to the Ruby file where the instruction sequence was loaded from.
<compiled> if the iseq was evaluated from a string.
- #absolute_path
-
The absolute path to the Ruby file where the instruction sequence was loaded from.
nil if the iseq was evaluated from a string.
- #first_lineno
-
The number of the first source line where the instruction sequence was loaded from.
- type
-
The type of the instruction sequence.
Valid values are :top, :method, :block, :class, :rescue, :ensure, :eval, :main, and :defined_guard.
- locals
-
An array containing the names of all arguments and local variables as symbols.
- params
-
An Hash object containing parameter information.
More info about these values can be found in vm_core.h.
- catch_table
-
A list of exceptions and control flow operators (rescue, next, redo, break, etc.).
- bytecode
-
An array of arrays containing the instruction names and operands that make up the body of the instruction sequence.
Note that this format is MRI specific and version dependent.
