Methods

Constructor __construct (line 154)

Make a new entry that can hold a signed long.

The method accept its arguments in two forms: several integer arguments or a single array argument. The getValue method will always return an array except for when a single integer argument is given here, or when an array with just a single integer is given.

PelEntrySLong __construct (PelTag $tag, int $value...)

int $value...: the long(s) that this entry will represent or an array of longs. The argument passed must obey the same rules as the argument to setValue, namely that it should be within range of a signed long (32 bit), that is between -2147483648 and 2147483647 (inclusive). If not, then a PelOverflowException will be thrown.
PelTag $tag: the tag which this entry represents. This should be one of the constants defined in PelTag which have format PelFormat::SLONG.

Redefined in descendants as:

PelEntrySRational::__construct() : Make a new entry that can hold a signed rational.

numberToBytes (line 176)

Convert a number into bytes.

return: bytes representing the number given.

string numberToBytes (int $number, PelByteOrder $order)

int $number: the number that should be converted.
PelByteOrder $order: one of PelConvert::LITTLE_ENDIAN and PelConvert::BIG_ENDIAN, specifying the target byte order.

Redefinition of:

PelEntryNumber::numberToBytes(): Convert a number into bytes.
