  • Constructor Details

    • BeanWrapperExpressionParser

      public BeanWrapperExpressionParser()
      Creates a new expression parser that uses a DefaultConversionService to perform type conversion.

    • BeanWrapperExpressionParser

      public BeanWrapperExpressionParser(ConversionService conversionService)
      Creates a new expression parser that uses the specified conversion service for type conversion.
      Parameters:
      conversionService - the conversion service to use

  • Method Details

    • getConversionService

      public ConversionService getConversionService()
      The conversion service to use to obtain conversion executors that will be adapted to property editors for use during a set value call. The default if not specified is an instance of DefaultConversionService.

    • setConversionService

      public void setConversionService(ConversionService conversionService)
      Sets the conversion service to use to obtain conversion executors that will be adapted to property editors for use during a set value call.
      Parameters:
      conversionService - the conversion service

    • setAutoGrowNestedPaths

      public void setAutoGrowNestedPaths(boolean autoGrowNestedPaths)
      Set whether this BeanWrapper should attempt to "auto-grow" a nested path that contains a null value.

      If "true", a null path location will be populated with a default object value and traversed instead of resulting in a NullValueInNestedPathException. Turning this flag on also enables auto-growth of collection elements when accessing an out-of-bounds index.

      Default is "false" on a plain BeanWrapper.

    • setAutoGrowCollectionLimit

      public void setAutoGrowCollectionLimit(int autoGrowCollectionLimit)
      Specify a limit for array and collection auto-growing.

      Default is unlimited on a plain BeanWrapper.

    • doParseExpression

      protected Expression doParseExpression(String expressionString, ParserContext context) throws ParserException
      Specified by:
      doParseExpression in class AbstractExpressionParser
      Throws:
      ParserException
