      Parameters:
      name - property name

  • Method Details

    • eqIfNotBlank

      public R eqIfNotBlank(@Nullable String value)
      Is equal to if the value is non-null and not blank, otherwise no expression is added to the query.

      This is like eqIfPresent() but additionally treats an empty or whitespace-only value as "not present". When present, the value is trimmed before being used in the equal to expression.

      This is a helper for building queries in fluid style where a String predicate is effectively optional, avoiding a separate if block and trimToNull() style helper. 

        List<Customer> customers = new QCustomer()
    .name.eqIfNotBlank(nameFilter)
    .status.eqIfPresent(statusFilter)
    .findList();
