Detailed Description

template<class Socket>
class RWTSocketAttribute< Socket >

RWTSocketAttribute encapsulates conditions that may be true for a socket. An RWTSocketAttribute serves two purposes: it is used to represent a set of attributes on a socket, and it is used to indicate that a particular attribute is true. It consists of two parts: the socket and the attribute.

Member Enumeration Documentation

Attribute

template<class Socket >

enum RWTSocketAttribute::Attribute

The Attribute type indicates the condition(s) on the socket. Attributes are used to indicate conditions of interest and to indicate what has happened on the socket. Attributes can be aggregated by ORing them together. For example, the attribute sock_attr_canread|sock_attr_canwrite on a socket indicates that the socket can either read or write.

The later enum values (NIL, CANREAD, CANWRITE, RWEXCEPTION, ISEXCEPTION, EXCEPTION, ISCONNECTED, CANACCEPT, ANY) have been retained, but are deprecated. You can refuse support for these values by defining the macro RW_DISABLE_DEPRECATED.

Enumerator
NIL	Deprecated As of SourcePro 1, use sock_attr_nil instead. No attributes.
CANREAD	Deprecated As of SourcePro 1, use sock_attr_canread instead. Data is available for reading.
CANWRITE	Deprecated As of SourcePro 1, use sock_attr_canwrite instead. Data is available for writing.
RWEXCEPTION	Deprecated As of SourcePro 1, use sock_attr_exception instead. An exception, such as an error or out-of-band data.
ISEXCEPTION	Deprecated As of SourcePro 1, use sock_attr_exception instead. An exception, such as an error or out-of-band data.
EXCEPTION	Deprecated As of SourcePro 1, use sock_attr_exception instead. An exception, such as an error or out-of-band data.
ISCONNECTED	Deprecated As of SourcePro 1, use sock_attr_isconnected instead. Connect has completed.
CANACCEPT	Deprecated As of SourcePro 1, use sock_attr_canaccept instead. A new connection is ready to be accepted.
ANY	Deprecated As of SourcePro 1, use sock_attr_any instead. Any Attribute
sock_attr_nil	No attributes.
sock_attr_canread	Data is available for reading.
sock_attr_canwrite	Data is available for writing.
sock_attr_exception	An exception, such as an error or out-of-band data.
sock_attr_isconnected	Connect has completed.
sock_attr_canaccept	A new connection is ready to be accepted.
sock_attr_any	Any Attribute

Member Function Documentation

getAttribute()

template<class Socket >

RWTSocketAttribute< Socket >::Attribute RWTSocketAttribute< Socket >::getAttribute ( void ) const

getSocket()

template<class Socket >

Socket RWTSocketAttribute< Socket >::getSocket ( void ) const

inline

The socket with which the attribute is associated.

operator=()

inline

Assignment operator.

Friends And Related Symbol Documentation

operator&

template<class Socket >

Attribute operator& ( Attribute lhs, Attribute rhs )

friend

Combines the attribute lhs with rhs using a bitwise or operation, and returns the result.

operator&=

template<class Socket >

Attribute & operator&= ( Attribute & lhs, Attribute rhs )

friend

Combines the attribute lhs with rhs using a bitwise and operation, stores the result into lhs, and returns the result.

operator==()

template<class Socket >

bool operator== ( const RWTSocketAttribute< Socket > & x, const RWTSocketAttribute< Socket > & y )

related

Returns true if x and y refer to the same attribute(s) on the same socket. Requires that Socket provide an equality operator.

operator^

template<class Socket >

Attribute operator^ ( Attribute lhs, Attribute rhs )

friend

Combines the attribute lhs with rhs using a bitwise exclusive or operation, and returns the result.

operator^=

template<class Socket >

Attribute & operator^= ( Attribute & lhs, Attribute rhs )

friend

Combines the attribute lhs with rhs using a bitwise exclusive or operation, stores the result into lhs, and returns the result.

operator|

template<class Socket >

Attribute operator| ( Attribute lhs, Attribute rhs )

friend

Combines the attribute lhs with rhs using a bitwise or operation, and returns the result.

operator|=

template<class Socket >

Attribute & operator|= ( Attribute & lhs, Attribute rhs )

friend

Combines the attribute lhs with rhs using a bitwise or operation, stores the result into lhs, and returns the result.

operator~

template<class Socket >

Attribute operator~ ( Attribute rhs )

friend

Inverts the value of the attribute rhs using a bitwise not operation, and returns the result.
