Class LinearPattern

java.lang.Object

org.panda_lang.framework.language.interpreter.pattern.linear.LinearPattern

public final class LinearPattern
extends Object

Fast pattern based on simple linear matching, uses only simple elements:

• unit
• wildcards:
  • simple (only one token)
  • expression
• section

Supports identifiers and optional elements.
Identifier is determined by the content before the : operator,
optional is determined by the & before the identifier, example:

&identifier:token

Sections are based on PandaSyntax,
its definition is determined by the ~ operator between separators. Usage:

class Test {~}

Wildcards are determined by the * operator.
Expression wildcards contains extra data defined by the =expression suffix, example:

identifier:*=expression
