Methods

Constructor __construct (line 74)

Make a new entry that can hold an unsigned byte.

The method accept several integer arguments. The getValue method will always return an array except for when a single integer argument is given here.

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

int $value...: the byte(s) that this entry will represent. The argument passed must obey the same rules as the argument to setValue, namely that it should be within range of an unsigned byte, that is between 0 and 255 (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 has format PelFormat::BYTE.

numberToBytes (line 96)

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.
