NAME

PPI::Structure::Unknown - An unknown or unresolved brace structure

INHERITANCE

  PPI::Structure::Unknown
  isa PPI::Structure
      isa PPI::Node
          isa PPI::Element

DESCRIPTION

"PPI::Structure::Unknown" is class for braces whose type is unknown, or temporarily unknown.

It primarily exists temporarily inside the lexer. Although some types of braces can be determined immediately at opening, there are a number of different brace types that can only be correctly identified after the braces are closed.

A structure is typed as unknown during this period it is indeterminate.

A "PPI::Structure::Unknown" object should not ever make it out of the lexer without being converted to its final type. Any time you encounter this class in a PDOM tree it should be considered a bug and reported accordingly.

METHODS

"PPI::Structure::Unknown" has no methods beyond those provided by the standard PPI::Structure, PPI::Node and PPI::Element methods.

SUPPORT

See the support section in the main module.
