  • public final class ConcatExpression
    extends Expression
    • Method Detail

      • getType

        public Type<?> getType()
        Description copied from class: Expression
        Gets the static type of the expression that this Expression represents.
        Overrides:
        getType in class Expression
        Returns:
        the Type that represents the static type of the expression.
      • accept

        protected Expression accept​(ExpressionVisitor visitor)
        Description copied from class: Expression
        Dispatches to the specific visit method for this node type. For example, BinaryExpression will call into ExpressionVisitor.visitBinary().
        Overrides:
        accept in class Expression
        Parameters:
        visitor - the visitor to visit this node.
        Returns:
        the result of visiting this node.
      • visitChildren

        protected Expression visitChildren​(ExpressionVisitor visitor)
        Description copied from class: Expression
        Reduces the node and then calls the visitor on the reduced expression. Throws an exception if the node isn't reducible.
        Overrides:
        visitChildren in class Expression
        Parameters:
        visitor - an expression visitor
        Returns:
        the expression being visited, or an expression which should replace it in the tree.
      • canReduce

        public boolean canReduce()
        Description copied from class: Expression
        Indicates that the node can be reduced to a simpler node. If this returns true, reduce() can be called to produce the reduced form.
        Overrides:
        canReduce in class Expression
        Returns:
        true if the node can be reduced; otherwise, false.
      • reduce

        public Expression reduce()
        Description copied from class: Expression
        Reduces this node to a simpler expression. If canReduce() returns true, this should return a valid expression. This method is allowed to return another node which itself must be reduced.
        Overrides:
        reduce in class Expression
        Returns:
        the reduced expression.
