class mira::ChannelReadWriteCommonBase< Derived >

Note

: NEVER EXPOSE THE CHANNELPTR OR CHANNEL DIRECTLY TO THE USER. The user is allowed to access the channel using the Channel<T> proxy ONLY!

Constructor & Destructor Documentation

ChannelReadWriteCommonBase() [1/2]

ChannelReadWriteCommonBase ( )

inline

Constructs an empty (invalid) ChannelReadWriteBase object.

ChannelReadWriteCommonBase() [2/2]

ChannelReadWriteCommonBase ( ChannelTypePtr  channel, Slot *  slot  )

inline

Constructs a valid ChannelReadWriteBase object that is assigned to a channel and slot.

Member Function Documentation

isValid()

bool isValid ( ) const

inline

Returns true, if data was assigned to the ChannelRead or ChannelWrite and if this data is locked.

If this method returns true, you can safely access the underlying data.

If this method returns false, no data was assigned to the ChannelRead / ChannelWrite or the lock on the data was lost. Hence, it is not safe to access the underlying data. If you try to access the data anyway you will get an XRuntime exception.

getChannelID()

const std::string& getChannelID ( )

inline

getTypename()

std::string getTypename ( ) const

inline

getTypeMeta()

TypeMetaPtr getTypeMeta ( ) const

inline

getTimestamp()

const Time& getTimestamp ( ) const

inline

getUseCount()

int getUseCount ( ) const

inline

Returns the number of shared instances for this data, may be useful for debugging purposes.

getFlags()

uint32 getFlags ( ) const

inline

For internal use only.

Used by remote components of the framework and by player and recorder. Returns current flags of this slot;

addFlags()

void addFlags ( uint32  moreFlags ) const

inline

For internal use only.

Used by remote components of the framework and by player and recorder. Add additional flags to the slots flags.

checkValid()

void checkValid ( ) const

inlineprotected

checks if we are still locked, if not it throws a XAccessViolation

readSerializedValue() [1/4]

const Buffer<uint8>& readSerializedValue ( )

inlineprotected

readSerializedValue() [2/4]

const Buffer<uint8>& readSerializedValue ( uint8  formatVersion, bool  orLower  )

inlineprotected

readSerializedValue() [3/4]

Buffer<uint8> readSerializedValue ( std::list< BinarySerializerCodecPtr > &  codecs )

inlineprotected

Same as above, but allows to specify codecs for serialization.

readSerializedValue() [4/4]

Buffer<uint8> readSerializedValue ( std::list< BinarySerializerCodecPtr > &  codecs, uint8  formatVersion, bool  orLower  )

inlineprotected

readJSON() [1/2]

void readJSON ( JSONValue &  oValue )

inlineprotected

readJSON() [2/2]

void readJSON ( JSONValue &  oValue, JSONSerializer &  serializer  )

inlineprotected

writeSerializedValue()

void writeSerializedValue ( Buffer< uint8 >  data )

inlineprotected

writeJSON() [1/2]

void writeJSON ( const JSONValue &  value )

inlineprotected

writeJSON() [2/2]

void writeJSON ( JSONDeserializer &  deserializer )

writeXML()

void writeXML ( const XMLDom::const_iterator &  node )
