List of toStringAST() Examples

Examples of toStringAST()

org.springframework.expression.spel.standard.SpelExpression.toStringAST()
Produce a string representation of the Abstract Syntax Tree for the expression, this should ideally look like the input expression, but properly formatted since any unnecessary whitespace will have been discarded during the parse of the expression. @return the string representation of the AST

Examples of org.springframework.expression.spel.standard.SpelExpression.toStringAST()

    SpelExpression expr = (SpelExpression) parser.parseExpression("'abc'.^[true]");
    assertEquals("'abc'.^[true]", expr.toStringAST());
    expr = (SpelExpression) parser.parseExpression("'abc'.?[true]");
    assertEquals("'abc'.?[true]", expr.toStringAST());
    expr = (SpelExpression) parser.parseExpression("'abc'.$[true]");
    assertEquals("'abc'.$[true]", expr.toStringAST());
  }
