Base class for AST Nodes of a ‘NodePattern`

def arity

Experimental RBS support (using type sampling data from the type_fusion project). 

def arity: () -> Integer

This signature was generated using 5 samples from 1 application.

Returns:
  • (Integer, Range) - An Integer for fixed length terms, otherwise a Range. 
def arity
  1
end

def arity_range

Experimental RBS support (using type sampling data from the type_fusion project). 

def arity_range: () -> Range

This signature was generated using 8 samples from 1 application.

Returns:
  • (Range) - arity as a Range 
def arity_range
  a = arity
  a.is_a?(Range) ? a : INT_TO_RANGE[a]
end

def capture? 

def capture?
  false
end

def child

Experimental RBS support (using type sampling data from the type_fusion project). 

def child: () -> Symbol

This signature was generated using 1 sample from 1 application.

Returns:
  • (Node) - most nodes have only one child 
def child
  children[0]
end

def children_nodes

Returns:
  • (Array) - 
def children_nodes
  children.grep(Node)
end

def in_sequence_head

Experimental RBS support (using type sampling data from the type_fusion project). 

def in_sequence_head: () -> nil

This signature was generated using 2 samples from 1 application.

Returns:
  • (Array, nil) - replace node with result, or `nil` if no change requested. 
def in_sequence_head
  nil
end

def matches_within_set?

Returns:
  • (Boolean) - returns true for nodes having a Ruby literal equivalent 
def matches_within_set?
  MATCHES_WITHIN_SET.include?(type)
end

def nb_captures

Returns:
  • (Integer) - nb of captures of that node and its descendants 
def nb_captures
  children_nodes.sum(&:nb_captures)
end

def rest? 

def rest?
  false
end

def source_range 

def source_range
  loc.expression
end

def variadic?

Returns:
  • (Boolean) - returns whether it matches a variable number of elements 
def variadic?
  arity.is_a?(Range)
end
