public class BoxExpressionVisitor extends ortus.boxlang.parser.antlr.BoxGrammarBaseVisitor<BoxExpression>
This class is responsible for visiting the parse tree and generating the AST for BoxScript expressions.

Some of the AST generation is complicated by the syntactical ambiguity of the language, where even precedence changes at certain points.

  • Constructor Details

    • BoxExpressionVisitor

      public BoxExpressionVisitor(BoxParser tools, BoxVisitor statementVisitor)

  • Method Details

    • getStatementVisitor

      public BoxVisitor getStatementVisitor()
      getter for statement visitor

    • visitTestExpression

      public BoxExpression visitTestExpression(ortus.boxlang.parser.antlr.BoxGrammar.TestExpressionContext ctx)
      This is here simply to allow tests to resolve a single expression without having to walk exprStaments
      Specified by:
      visitTestExpression in interface ortus.boxlang.parser.antlr.BoxGrammarVisitor<BoxExpression>
      Overrides:
      visitTestExpression in class ortus.boxlang.parser.antlr.BoxGrammarBaseVisitor<BoxExpression>
      Parameters:
      ctx - the parse tree
      Returns:
      the expression

    • visitExprPrecedence

      public BoxExpression visitExprPrecedence(ortus.boxlang.parser.antlr.BoxGrammar.ExprPrecedenceContext ctx)
      Manufactures an AST node that indicates that the wrapped expression is in parentheses.

      Generally, one does not explicitly put this in an AST. If we need to regenerate the source we can see that an expression was parenthesised because the operator precedence will be different. However, in some cases it is useful to have this information in the AST, for instance if we wish to preserve redundant parentheses.

      Specified by:
      visitExprPrecedence in interface ortus.boxlang.parser.antlr.BoxGrammarVisitor<BoxExpression>
      Overrides:
      visitExprPrecedence in class ortus.boxlang.parser.antlr.BoxGrammarBaseVisitor<BoxExpression>
      Parameters:

      The AST for the parenthesised expression

    • visitExprDotOrColonAccess

      public BoxExpression visitExprDotOrColonAccess(ortus.boxlang.parser.antlr.BoxGrammar.ExprDotOrColonAccessContext ctx)
      visits the Dot accessor operation and generates the relevant AST.

      With dot accessors, there some special cases where the left and right are folded into one node rather than encapsulated into a DotAccess. For example method invocations will be seen on the right of x.y() and the invocation AST for y() will have the x reference folded into it.

      Overrides:
      visitExprDotOrColonAccess in class ortus.boxlang.parser.antlr.BoxGrammarBaseVisitor<BoxExpression>

    • buildRelOp

      public BoxComparisonOperator buildRelOp(ortus.boxlang.parser.antlr.BoxGrammar.RelOpsContext ctx)
      Visit the relational operator context to generate the AST node for the operator.

      As the operations seem to have grown in the telling so to speak, there are some wierd and wonderful combinations that are utterly superfluous even as syntactic sugar. However, as they are in the language, we must deal with them.

      Parameters:
      ctx - the parse tree
      Returns:
      the operation AST node

    • buildBinOp

      public BoxBinaryOperator buildBinOp(ortus.boxlang.parser.antlr.BoxGrammar.BinOpsContext ctx)
      Visit the relational operator context to generate the AST node for the operator.

      As the operations seem to have grown in the telling so to speak, there are some wierd and wonderful combinations that are utterly superfluous even as syntactic sugar. However, as they are in the language, we must deal with them.

      Parameters:
      ctx - the parse tree
      Returns:
      the operation AST node

    • buildAssignmentModifier

      public BoxAssignmentModifier buildAssignmentModifier(ortus.boxlang.parser.antlr.BoxGrammar.AssignmentModifierContext ctx)

    • visitErrorNode

      public BoxExpression visitErrorNode(org.antlr.v4.runtime.tree.ErrorNode node)
      A special node is inserted into the tree when a parser error is encountered. Here we provide a visitor to handle such nodes so that we can call the visitor even when the parser rejected the input
      Specified by:
      visitErrorNode in interface org.antlr.v4.runtime.tree.ParseTreeVisitor<BoxExpression>
      Overrides:
      visitErrorNode in class org.antlr.v4.runtime.tree.AbstractParseTreeVisitor<BoxExpression>
      Parameters:
      node - the error node
      Returns:
      a New error node so that AST building can work
