  # Sets an element of the array
  $blessed_object_array->set(2 => 5);
  
  # Converts a SPVM array to a Perl array reference
  my $elems = $blessed_object_array->to_elems;
  
  # Converts a SPVM array to a binary
  my $binary = $blessed_object_array->to_bin;

Methods

get

  my $elem = $blessed_object_array->get($index);

Returns an element of the array with the index.

set

  $blessed_object_array->set($index, $elem);

  my $binary = $blessed_object_array->to_bin;

Converts a SPVM array to a binary and returns it.

This binary is unpacked by unpack function.

If the array is an object array, an excetion is thrown.

Examples:

  # byte[]
  my @elems = unpack 'c*', $binary;
  
  # short[]
  my @elems = unpack 's*', $binary;
  
  # int[]
  my @elems = unpack 'l*', $binary;

  # long[]
  my @elems = unpack 'q*', $binary;

  # float[]
  my @elems = unpack 'f*', $binary;

  # double[]
  my @elems = unpack 'd*', $binary;

to_strings

  my $elems = $blessed_object_array->to_strings;

Converts a SPVM string array to a Perl array reference and returns it.

Each element calls to_string method.

to_bins

  my $elems = $blessed_object_array->to_bins;

Converts a SPVM string array to Perl array reference and returns it.

Each element calls to_bin method.
