Member Function Documentation

uint ito::Channel::getHash ( ) const

inline

The hash identifying this channel in the connection list of the participating nodes

ito::Param* ito::Channel::getOwnParam ( AbstractNode *  self ) const

inline

returns the own node's parameter participating in this channel. Note: The roles of sender/receiver are not relevant in this context

ito::Param* ito::Channel::getPartnerParam ( AbstractNode *  self ) const

inline

returns the other node's parameter participating in this channel. Note: The roles of sender/receiver are not relevant in this context

AbstractNode* ito::Channel::getReceiver ( void  ) const

inline

returns a pointer to the node filling the role of receiver in this channel. Useful, since parent/child do not have predefined roles

AbstractNode* ito::Channel::getSender ( void  ) const

inline

returns a pointer to the node filling the role of sender in this channel. Useful, since parent/child do not have predefined roles

bool ito::Channel::isReceiver ( AbstractNode *  query ) const

inline

returns true, if the node given as the argument fills the role of receiver in this channel. Useful, since parent/child do not have predefined roles

bool ito::Channel::isSender ( AbstractNode *  query )

inline

returns true, if the node given as the argument fills the role of sender in this channel. Useful, since parent/child do not have predefined roles

ito::RetVal Channel::propagateUpdatePending

(

)

prepares the whole sub tree of nodes rooted at the sending node of this channel for an incoming update. Note: this function does NOT propagate any actual data

void ito::Channel::resetUpdatePending ( void  )

inline

Sets the updatePending flag of this channel back to false. Note: This reset is NOT propagated down the node tree

Member Data Documentation

ChanDirection ito::Channel::m_direction

private

The node that is not the parent. Note: the child is NOT necessarily the receiver in the channel

AbstractNode* ito::Channel::m_pChild

private

The node calling the constructor of the channel. Note: the parent is NOT necessarily the sender in the channel

AbstractNode* ito::Channel::m_pParent

private

Unique indentifier used in the UiOrganizer

ito::Param* ito::Channel::m_pParentParam

private

Defines whether the parent or the child are the sender/receiver in this channel

unsigned int ito::Channel::m_uniqueID

private

Running counter for nodes created in the UiOrganizer

bool ito::Channel::m_updatePending

private

Flags defining the behaviour of the connected nodes upon a disconnect. If one of

these flags is set to TRUE, the corresponding node is deleted, when the connection is cut. Note:
