Holds a resizable array of primitive or copy-by-value objects.
Definition juce_Array.h:60
Represents a MAC network card adapter address ID.
bool isNull() const noexcept
Returns true if this address is null (00-00-00-00-00-00).
String toString() const
Returns a dash-separated string in the form "11-22-33-44-55-66".
static void findAllAddresses(Array< MACAddress > &results)
Populates a list of the MAC addresses of all the available network cards.
MACAddress & operator=(const MACAddress &) noexcept
Creates a copy of another address.
int64 toInt64() const noexcept
Returns the address in the lower 6 bytes of an int64.
static Array< MACAddress > getAllAddresses()
Returns a list of the MAC addresses of all the available network cards.
MACAddress() noexcept
Creates a null address (00-00-00-00-00-00).
A class to hold a resizable block of raw data.
size_t getSize() const noexcept
Returns the block's current allocated size, in bytes.
void loadFromHexString(StringRef sourceHexString)
Parses a string of hexadecimal numbers and writes this data into the memory block.
void * getData() const noexcept
Returns a void pointer to the data.
A simple class for holding temporary references to a string literal or String.
The JUCE String class!
Definition juce_String.h:43
String paddedLeft(juce_wchar padCharacter, int minimumLength) const
Returns a copy of this string with the specified character repeatedly added to its beginning until th...
static String toHexString(IntegerType number)
Returns a string representing this numeric value in hexadecimal.
