Detailed Description

Abstract block class with behavior for a collection of trials.

A block is created by typing run at the Text Display. It then reads in a target file and creates as many trial objects as lines in the target file. It then runs these trials and saves the data to disk.

Constructor & Destructor Documentation

Block::Block

(

)

Constructor.

The Constructor only sets the number of Trials to zero

Block::~Block

(

)

Destructor.

Destructor frees the memory allocated by the block, including the recorded data

Member Function Documentation

bool Block::init	(	int	blockn,
		string	filename
	)		[virtual]

initialize the Trials

Initializes the Block by reading from a target file init makes the .mov and .dat file for later data saving. Calls Trial::read to specify how a trial is read

Parameters:

blockn	Block number
filename	Name of the target file to be read in

Returns:

boolean whether successful or not

void Block::control

(

)

[virtual]

control loop for block

Control loop for the Block. When started it calls start(). Then it sets the state of the first trial to START_TRIAL and waits until it is in the state END_TRIAL. Then it automatically advances to the next trial. After the block it calls give_feedback and save.

See also:

start() give_feedback() save() end()

check if user interrupted current block

void Block::save

(

)

[virtual]

save mov and dat file

Saves the data collected in a Block. Gives error message if files could not be opened for writing. The routine calls trial->writeDat() to write a line in the dat file, and trial->writeMov() to write a trial into the mov file

See also:

Trial::writeDat() Trial::writeMov() Trial::writeHeader()
