Utility class for type-safe combinations of enumeration flags.
This type is used in Wt API whenever one or more flag options are expected, instead of an int. The class provides type safety, in the sense that it checks that the correct combination of enum values is bound to the argument, and does not cost any run-time overhead (internally it uses only an int to represent the combination of flags.
| Wt::WFlags< EnumType >::operator EnumType | ( | ) | const |
Cast to the enum type.
The internal int representation is simply cast to the enum type, without any additional checks.
| bool Wt::WFlags< EnumType >::operator! | ( | ) | const |
Negation operator.
Returns whether different from 0.
| WFlags< EnumType > Wt::WFlags< EnumType >::operator& | ( | EnumType | mask | ) | const |
Bitwise AND operator.
Returns flags that are the bitwise AND of this and mask.
| WFlags< EnumType > Wt::WFlags< EnumType >::operator& | ( | MaskType | mask | ) | const |
Bitwise AND operator.
Returns flags that are the bitwise AND of this and mask.
| WFlags< EnumType > & Wt::WFlags< EnumType >::operator&= | ( | EnumType | mask | ) |
Modifying bitwise AND operator.
Sets as value the bitwise AND of this and mask.
| WFlags< EnumType > & Wt::WFlags< EnumType >::operator&= | ( | MaskType | mask | ) |
Modifying bitwise AND operator.
Sets as value the bitwise AND of this and mask.
| WFlags< EnumType > Wt::WFlags< EnumType >::operator^ | ( | WFlags< EnumType > | other | ) | const |
Bitwise XOR operator.
Returns flags that are the bitwise XOR of this and other.
| WFlags< EnumType > Wt::WFlags< EnumType >::operator^ | ( | EnumType | other | ) | const |
Bitwise XOR operator.
Returns flags that are the bitwise XOR of this and other.
| WFlags< EnumType > & Wt::WFlags< EnumType >::operator^= | ( | WFlags< EnumType > | other | ) |
Modifying bitwise XOR operator.
Sets as value the bitwise XOR of this and other.
| WFlags< EnumType > & Wt::WFlags< EnumType >::operator^= | ( | EnumType | other | ) |
Modifying bitwise XOR operator.
Sets as value the bitwise XOR of this and other.
| WFlags< EnumType > Wt::WFlags< EnumType >::operator| | ( | WFlags< EnumType > | other | ) | const |
Bitwise OR operator.
Returns flags that are the bitwise OR of this and other.
| WFlags< EnumType > Wt::WFlags< EnumType >::operator| | ( | EnumType | other | ) | const |
Bitwise OR operator.
Returns flags that are the bitwise OR of this and other.
| WFlags< EnumType > & Wt::WFlags< EnumType >::operator|= | ( | WFlags< EnumType > | other | ) |
Modifying bitwise OR operator.
Sets as value the bitwise OR of this and other.
| WFlags< EnumType > & Wt::WFlags< EnumType >::operator|= | ( | EnumType | other | ) |
Modifying bitwise OR operator.
Sets as value the bitwise OR of this and other.
| WFlags< EnumType > Wt::WFlags< EnumType >::operator~ | ( | ) | const |
Inversion operator.
Returns flags that are the inverted of this.
