Public Methods

CoinMpsCardReader

Constructor expects file to be open This one takes gzFile if fp null.

 CoinMpsCardReader(CoinFileInput * input, CoinMpsIO * reader)

Parameters:

• input (CoinFileInput *)
• reader (CoinMpsIO *)

~CoinMpsCardReader

Destructor.

 ~CoinMpsCardReader()

readToNextSection

Read to next section.

COINSectionType readToNextSection()

nextField

Gets next field and returns section type e.g. COIN_COLUMN_SECTION.

COINSectionType nextField()

nextGmsField

Gets next field for .gms file and returns type.

int nextGmsField(int expectedType)

Parameters:

• expectedType (int)

whichSection

Returns current section type.

COINSectionType whichSection()

setWhichSection

Sets current section type.

void setWhichSection(COINSectionType section)

Parameters:

• section (COINSectionType)

freeFormat

Sees if free format.

bool freeFormat()

setFreeFormat

Sets whether free format. Mainly for blank RHS etc.

void setFreeFormat(bool yesNo)

Parameters:

• yesNo (bool)

mpsType

Only for first field on card otherwise BLANK_COLUMN e.g.

COINMpsType mpsType()

cleanCard

Reads and cleans card - taking out trailing blanks - return 1 if EOF.

int cleanCard()

rowName

Returns row name of current field.

const char * rowName()

columnName

Returns column name of current field.

const char * columnName()

value

Returns value in current field.

double value()

valueString

Returns value as string in current field.

const char * valueString()

card

Whole card (for printing)

const char * card()

mutableCard

Whole card - so we look at it (not const so nextBlankOr will work for gms reader)

char * mutableCard()

setPosition

set position (again so gms reader will work)

void setPosition(char * position)

Parameters:

• position (char *)

getPosition

get position (again so gms reader will work)

char * getPosition()

cardNumber

Returns card number.

CoinBigIndex cardNumber()

fileInput

Returns file input.

CoinFileInput * fileInput()

setStringsAllowed

Sets whether strings allowed.

void setStringsAllowed()

double osi_strtod(char * ptr, char ** output, int type)

Parameters:

• ptr (char *)
• output (char **)
• type (int)

osi_strtod

For strings.

double osi_strtod(char * ptr, char ** output)

Parameters:

• ptr (char *)
• output (char **)

strcpyAndCompress

remove blanks

void strcpyAndCompress(char * to, const char * from)

Parameters:

• to (char *)
• from (const char *)
