Class Method Summary

Node - Inherited

.fields

Returns a list of the fields that exist for this node class.
.type

Similar to #type, this method returns a symbol that you can use for splitting on the type of the node without having to do a long === chain.

Instance Attribute Summary

  • #value readonly

    The value of the floating point number as a Float.

Node - Inherited

#newline?

Returns true if the node has the newline flag set.
#node_id

A unique identifier for this node.
#static_literal?

Returns true if the node has the static literal flag set.
#flags

An bitset of flags for this node.
#source

A pointer to the source that this node was created from.
#newline_flag?

Instance Method Summary

Node - Inherited

#accept

Accepts a visitor and calls back into the specialized visit function.
#breadth_first_search

Returns the first node that matches the given block when visited in a depth-first search.
#cached_end_code_units_column

Delegates to the cached_end_code_units_column of the associated location object.

Delegates to the cached_end_code_units_offset of the associated location object.
#cached_start_code_units_column

Delegates to the cached_start_code_units_column of the associated location object.
#cached_start_code_units_offset

Delegates to the cached_start_code_units_offset of the associated location object.
#child_nodes

Returns an array of child nodes, including nils in the place of optional nodes that were not present.
#comment_targets

Returns an array of child nodes and locations that could potentially have comments attached to them.
#comments

Delegates to the comments of the associated location object.
#compact_child_nodes

Returns an array of child nodes, excluding any nils in the place of optional nodes that were not present.

Returns a string representation of the node.
#leading_comments

Delegates to the leading_comments of the associated location object.
#location

A Location instance that represents the location of this node in the source.
#pretty_print

Similar to inspect, but respects the current level of indentation given by the pretty print object.
#save

Save this node using a saved source so that it can be retrieved later.
#save_location

Save the location using a saved source so that it can be retrieved later.
#script_lines

Alias for Node#source_lines.
#slice

Slice the location of the node from the source.
#slice_lines

Slice the location of the node from the source, starting at the beginning of the line that the location starts on, ending at the end of the line that the location ends on.
#source_lines

Returns all of the lines of the source code associated with this node.
#start_character_column

Delegates to the start_character_column of the associated location object.
#start_character_offset

Delegates to the start_character_offset of the associated location object.
#start_column

Delegates to the start_column of the associated location object.
#start_line

Delegates to the start_line of the associated location object.
#start_offset

The start offset of the node in the source.
#to_dot

Convert this node into a graphviz dot graph string.
#trailing_comments

Delegates to the trailing_comments of the associated location object.
#tunnel

Returns a list of nodes that are descendants of this node that contain the given line and column.
#type

Sometimes you want to check an instance of a node against a list of classes to see what kind of behavior to perform.
#deprecated, #newline_flag!
