Member Function Documentation

const string & TruthMatrix::getColname

(

unsigned int

index

)

const [virtual]

Gets the column name

------------------------------- Parameters ------------------------------- unsigned int index The column id

--------------------------------- Return --------------------------------- The name of that column

const string & TruthMatrix::getFilename

(

)

const [virtual]

Gets the filename for the matrix.

--------------------------------- Return --------------------------------- The filename of the matrix

bool TruthMatrix::getRow

(

bool *

row

)

[virtual]

Gets a row

------------------------------- Parameters ------------------------------- const TruthMatrix& rhs The right hand side

--------------------------------- Return --------------------------------- true There is another row left false There are no more rows left

bool TruthMatrix::getRow	(	string &	rowname,
		bool *	row
	)		[virtual]

Reads in a row from the matrix

------------------------------- Parameters ------------------------------- string& rowname The name of row bool* row This is where we put the row data

--------------------------------- Return --------------------------------- false if there are no more rows left

const string & TruthMatrix::getRowType

(

unsigned int

index

)

const

Returns the row type (The field in the upper left of the file)

--------------------------------- Return --------------------------------- The row type

unsigned int TruthMatrix::height

(

)

[virtual]

Returns the height of the matrix. Does not count column names.

--------------------------------- Return --------------------------------- The height of the matrix

bool TruthMatrix::isOpen

(

)

[virtual]

Makes sure our stream is open.

--------------------------------- Return --------------------------------- Whether or not the stream is open.

TruthMatrix & TruthMatrix::operator=

(

const TruthMatrix &

rhs

)

[virtual]

The = operator

------------------------------- Parameters ------------------------------- const TruthMatrix& rhs The right hand side

--------------------------------- Return --------------------------------- A referenc to the new matrix

void TruthMatrix::rewind

(

)

[virtual]

Rewinds the file

const char * TruthMatrix::setFile

(

const char *

filename

)

[virtual]

Reads in the column names and sets variables needed for grabbing rows in the future

------------------------------- Parameters ------------------------------- const char* filename The name of the file

--------------------------------- Return --------------------------------- NULL The file is valid The error message

void TruthMatrix::transpose

(

const char *

coltype

)

[virtual]

Transposes the matrix if coltype is not null

------------------------------- Parameters ------------------------------- const char* coltype The name for the new column type. Ie: if it was bills before, it should now be senators

unsigned int TruthMatrix::width

(

)

[virtual]

Returns the width of the matrix. Does not count row names.

--------------------------------- Return --------------------------------- The width of the matrix
