Member Function Documentation

getNext()

template<class T >

T * iCub::learningmachine::FileReaderT< T >::getNext ( )

inline

Returns a pointer to the next item in the file.

Note that the caller takes responsibility for cleaning the memory space associated with the pointer.

Returns

a pointer to the new item

Exceptions

std::runtime_error	no open stream
std::runtime_error	end of stream

Definition at line 148 of file FileReaderT.h.

hasNext()

template<class T >

virtual bool iCub::learningmachine::FileReaderT< T >::hasNext ( )

inlinevirtual

Checks whether there are more items left in the stream.

Returns

true if the stream has more items left

Exceptions

std::runtime_error

no open stream

Definition at line 123 of file FileReaderT.h.

open() [1/2]

template<class T >

virtual void iCub::learningmachine::FileReaderT< T >::open ( const std::string &  f )

inlinevirtual

Opens a stream to the given filename for reading.

Parameters

f	the filename

Definition at line 105 of file FileReaderT.h.

open() [2/2]

template<class T >

virtual void iCub::learningmachine::FileReaderT< T >::open ( std::istream &  s )

inlinevirtual

Opens the given stream for reading.

Parameters

s	the input stream

reset()

template<class T >

virtual void iCub::learningmachine::FileReaderT< T >::reset ( )

inlinevirtual

Resets the stream to the beginning.

Note that this may not be possible for specific combinations of streams (e.g. stdin) and platforms.
