Methods

Constructor __construct (line 571)

Make a new entry that can hold a signed short.

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

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

int $value...: the signed short(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 a signed short, that is between -32768 to 32767 (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::SSHORT.

numberToBytes (line 593)

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.
