MalformedBooleanNumberComparisonExpressionException class

An exception thrown by DartBlock when calculating the value of a DartBlockBooleanExpression.

Cases include:

  • the left operand, the right operand and the operator being null. (example: <operand> <operator> <operand>)
  • the operator being null, while the left operand and the right operand are non-null. (example: 4 <operator> 5)
  • the left operand and the operator being null, while the right operand is non-null. (example: <operand> <operator> 5)
  • the right operand and the operator being null, while the left operand is non-null. (example: 4 <operator> <operand>)
  • the left operand and the right operand being null, while the operator is non-null. (example: <operand> == <operand>)
  • the left operand being null, while the right operand and the operator are non-null. (example: <operand> == 5)
  • the right operand being null, while the left operand and the operator are non-null. (example: 4 == <operand>)
