Class BracketedExpression

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.

• accept

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

• 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.

• equals

  public boolean equals(Object o)

• canEqual

  protected boolean canEqual(Object other)

• hashCode

  public int hashCode()

• getExpression

  public Expression getExpression()

• 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
