Detailed Description

template<class DataType>
class RTC::InPort< DataType >

InPort template class.

This is a template class that implements InPort. <T> is the type defined in BasicDataType.idl and must be the structure which has both Time type tm and type-T data as a member. InPort has a ring buffer internally, and stores the received data externally in this buffer one by one. The size of ring buffer can be specified according to the argument of constructor, though the default size is 64. Unread data and data which is already read are managed with the flag, and the data can be handled by the isNew(), write(), read(), isFull() and isEmpty() method etc.

Since
0.2.0

A constructor.

constructor. This is bound to type-T variable given as a parameter.

Parameters
nameA name of the InPort. This name is referred by InPortBase::name().
valuetype-T variable that is bound to this InPort.
bufsizeBuffer length of internal ring buffer of InPort (The default value:64)
read_blockFlag of reading block. When there are not unread data at reading data, set whether to block data until receiving the next data. (The default value:false)
write_blockFlag of writing block. If the buffer was full at writing data, set whether to block data until the buffer has space. (The default value:false)
read_timeoutData reading timeout time (millisecond) when not specifying read blocking. (The default value:0)
write_timeoutData writing timeout time (millisecond) when not specifying writing block. (The default value:0)

Member Function Documentation

template<class DataType >
DataPortStatus::Enum RTC::InPort< DataType >::getStatus ( int  index)
inline

Getting specified connector's writing status.

An InPort has Connectors that are virtual data stream channel for each connection. "write()" function write into these Connectors, and each Connector returns writing-status. write() function will return a true value if all Connectors return normal status, and a false value will be returned if at least one Connector failed. This function can be used to inspect each return status

Parameters
indexConnector index
Returns
Writing status
template<class DataType >
DataPortStatusList RTC::InPort< DataType >::getStatusList ( )
inline

Getting specified connector's writing status list.

An InPort has Connectors that are virtual data stream channel for each connection. "write()" function write into these Connectors, and each Connector returns writing-status. write() function will return a true value if all Connectors return normal status, and a false value will be returned if at least one Connector failed. This function can be used to inspect each return status

Returns
Writing status list
template<class DataType >
virtual bool RTC::InPort< DataType >::isEmpty ( void  )
inlinevirtual

Check whether the data is newest.

Check whether the data stored at a current buffer position is newest.

Returns
Newest data check result ( true:Newest data. Data has not been readout yet. false:Past data.Data has already been readout.)

Reimplemented from RTC::DirectInPortBase< DataType >.

References RTC::InPortBase::m_connectors, RTC::PortBase::m_connectorsMutex, RTC_DEBUG, and RTC_TRACE.

template<class DataType >
virtual bool RTC::InPort< DataType >::isNew ( )
inlinevirtual

Check whether the data is newest.

Check whether the data stored at a current buffer position is newest.

Returns
Newest data check result ( true:Newest data. Data has not been readout yet. false:Past data.Data has already been readout.)

Reimplemented from RTC::DirectInPortBase< DataType >.

References RTC::InPortBase::m_connectors, RTC::PortBase::m_connectorsMutex, RTC_DEBUG, and RTC_TRACE.

template<class DataType >
virtual const char* RTC::InPort< DataType >::name ( )
inlinevirtual

Get port name.

Get port name.

Returns
The port name
template<class DataType >
void RTC::InPort< DataType >::operator>> ( DataType &  rhs)
inline

Read the newly value data in InPort to type-T variable.

Read the newly data set in InPort and set to specified data variable.

Parameters
rhsThe type-T variable to read from InPort's buffer

References RTC::InPort< DataType >::read().

template<class DataType >
bool RTC::InPort< DataType >::read ( )
inlinevirtual

Readout the value from DataPort.

Readout the value from DataPort

  • When Callback functor OnRead is already set, OnRead will be invoked before reading from the buffer held by DataPort.
  • When the buffer held by DataPort can detect the underflow, and when it detected the underflow at reading, callback functor OnUnderflow will be invoked.
  • When callback functor OnReadConvert is already set, the return value of operator() of OnReadConvert will be the return value of read().
  • When timeout of reading is already set by setReadTimeout(), it waits for only timeout time until the state of the buffer underflow is reset, and if OnUnderflow is already set, this will be invoked to return.
Returns
Readout result (Successful:true, Failed:false)

Implements RTC::InPortBase.

template<class DataType >
void RTC::InPort< DataType >::setOnRead ( OnRead< DataType > *  on_read)
inline

Set callback when data is read from the InPort buffer.

Set the callback object that is invoked right before data is read from the InPort's buffer

Parameters
on_readOnRead<DataType> type object
template<class DataType >
void RTC::InPort< DataType >::setOnReadConvert ( OnReadConvert< DataType > *  on_rconvert)
inline

Set callback when data is readout to the InPort buffer.

Set the callback object that is invoked when data is readout to the InPort's buffer. The return value of callback object is the return result of the read() method.

Parameters
on_rconvertOnReadConvert<DataType> type object
template<class DataType >
virtual void RTC::InPort< DataType >::update ( void  )
inlinevirtual

Read the newly value to type-T variable which is bound to InPort's buffer.

Read the newly value to type-T data which is bound to InPort's buffer. The type-T variable must be bound to InPort in constructor. Since this method assumes to be used for polymorphic, its argument and the return value do not depend on type.
