Instance Method Details

#init ⇒ Expression

Returns tree node for init expression.

Returns:

• (Expression) —

  tree node for init expression

# File 'lib/parser/parser_nodes.rb', line 1117

def init
  tree_nodes = recursive_select(Sexp::Expression).first      
end

#name ⇒ Object

# File 'lib/parser/parser_nodes.rb', line 1106

def name
  recursive_select(Sexp::Identifier).first.node_value
end

#symbol_definitions ⇒ Array

Return entries for symbol table. In this case, add just variable definition.

Returns:

• (Array) —

  of 1 hash with :node_type, :value -properties

# File 'lib/parser/parser_nodes.rb', line 1124

def symbol_definitions
  [ { :node_type => node_type, :value => name } ]
end

#variable ⇒ Identifier

Returns tree node for variable defined.

Returns:

• (Identifier) —

  tree node for variable defined

# File 'lib/parser/parser_nodes.rb', line 1111
