Package nz.org.riskscape.rl.ast

Class FunctionCall

java.lang.Object
nz.org.riskscape.rl.ast.FunctionCall
All Implemented Interfaces:
Expression
public final class FunctionCall extends Object

  • Constructor Details

  • Method Details

    • appendSource

      protected void appendSource(StringBuilder appendTo)

      Implementers extend this to append their source to the given string builder. Done via string builder to encourage a more efficient implementation than is possible with concatenating multiple toString calls that typically contruct a string builder anyway.

    • keywordArgumentsOffset

      public int keywordArgumentsOffset()

    • hasKeywordArguments

      public boolean hasKeywordArguments()

    • indexOfArgNamed

      public int indexOfArgNamed(String toFind)
      Returns:
      argIndex of argument with name toFind, or -1 if not found

    • accept

      public <T, R> R accept(ExpressionVisitor<T,R> visitor, T data)

    • getPositionalArguments

      public List<FunctionCall.Argument> getPositionalArguments()

      Builds a list of all the arguments that were given before the first keyword argument appears

      Note that the parser is currently allowing (I think) positional elements to occur after keywords, which will break this code. We should probably stop this as I'm 99% sure we never want positional args to be interleaved with keyword args

    • equals

      public boolean equals(Object o)

    • canEqual

      protected boolean canEqual(Object other)

    • hashCode

      public int hashCode()

    • getIdentifier

      public Token getIdentifier()

    • getArguments

      public List<FunctionCall.Argument> getArguments()

    • getBoundary

      public Optional<Pair<Token,Token>> getBoundary()
      Returns:
      a pair of tokens that represent the start and end of this expression, to be used when giving users information about where errors have occurred. If the expression has been rebuilt then the boundary may be empty or it may be from the original expression. Intended for use in problems to trace errors back to their source.

    • toString

      public final String toString()
      Overrides:
      toString in class Object
      Returns:
      the source, surrounded by the class name to make it easier to discern from a plane string among other debug output

    • toSource

      public final String toSource()
      Specified by:
      toSource in interface Expression
      Returns:
      a normalized version of the AST that can be parsed to be exactly the same AST as this
