com.scriptbasic.syntax.expression.BasicTagAnalyzer

All Implemented Interfaces:

Analyzer<Expression>, FactoryManaged, TagAnalyzer

public final class BasicTagAnalyzer
extends AbstractAnalyzer<Expression>
implements TagAnalyzer

Analyze a tag. A tag is the most primitive part of an expression that does not contain any further operators (unless the operators are enclosed between brackets some way).

A tag is defined as the following:

  tag ::= UNOP tag
          TRUE | FALSE
          NUMBER
          STRING
          '(' expression ')'
          VARIABLE { '[' expression_list ']' }
          FUNC '(' expression_list ')'
