Detailed Description

ByteArray - Arrays of bytes.

ByteArray is a mutable array of bytes, to provide arrays of bytes which grow automatically as elements are added.

To create a new ByteArray use create(). To add elements to a ByteArray, use append(), and prepend().

To set the size of a ByteArray, use set_size().

Since glibmm 2.36:

Member Typedef Documentation

◆ SlotCompare

A Slot type to compare two elements in the array.

The slot should return -1 if the first value is less than the second, 0 if they are equal and 1 if the first value is greater than the second.

Slot Prototype:

int compare(const guint8* first, const guint8* second);

Constructor & Destructor Documentation

◆ ByteArray() [1/2]

Glib::ByteArray::ByteArray ( )
delete

◆ ByteArray() [2/2]

Glib::ByteArray::ByteArray ( const ByteArray )
delete

Member Function Documentation

◆ append()

Glib::RefPtr< ByteArray > Glib::ByteArray::append ( const guint8 data,
guint  len 
)

Adds the given bytes to the end of the ByteArray.

The array will grow in size automatically if necessary.

Parameters
dataThe byte data to be added.
lenThe number of bytes to add.
Returns
The ByteArray.

◆ create()

static Glib::RefPtr< ByteArray > Glib::ByteArray::create ( )
static

Creates a new ByteArray with a reference count of 1.

Returns
The new ByteArray.

◆ get_data() [1/2]

guint8 * Glib::ByteArray::get_data ( )

Gets the data of the byte array.

Returns
The data.
Since glibmm 2.36:

◆ get_data() [2/2]

const guint8 * Glib::ByteArray::get_data ( ) const

Gets the data of the byte array.

Returns
The data.
Since glibmm 2.36:

◆ get_type()

static GType Glib::ByteArray::get_type ( )
static

Get the GType for this class, for use with the underlying GObject type system.

◆ gobj() [1/2]

GByteArray * Glib::ByteArray::gobj ( )

Provides access to the underlying C instance.

◆ gobj() [2/2]

const GByteArray * Glib::ByteArray::gobj ( ) const

Provides access to the underlying C instance.

◆ gobj_copy()

GByteArray * Glib::ByteArray::gobj_copy ( ) const

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

◆ operator delete()

void Glib::ByteArray::operator delete ( void ,
std::size_t   
)
protected

◆ operator=()

ByteArray & Glib::ByteArray::operator= ( const ByteArray )
delete

◆ prepend()

Glib::RefPtr< ByteArray > Glib::ByteArray::prepend ( const guint8 data,
guint  len 
)

Adds the given data to the start of the ByteArray.

The array will grow in size automatically if necessary.

Parameters
dataThe byte data to be added.
lenThe number of bytes to add.
Returns
The ByteArray.

◆ reference()

void Glib::ByteArray::reference ( ) const

Increment the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

◆ remove_index()

Glib::RefPtr< ByteArray > Glib::ByteArray::remove_index ( guint  index)

Removes the byte at the given index from a ByteArray.

The following bytes are moved down one place.

Parameters
indexThe index of the byte to remove.
Returns
The ByteArray.

◆ remove_index_fast()

Glib::RefPtr< ByteArray > Glib::ByteArray::remove_index_fast ( guint  index)

Removes the byte at the given index from a ByteArray.

The last element in the array is used to fill in the space, so this function does not preserve the order of the ByteArray. But it is faster than g_byte_array_remove_index().

Parameters
indexThe index of the byte to remove.
Returns
The ByteArray.

◆ remove_range()

Glib::RefPtr< ByteArray > Glib::ByteArray::remove_range ( guint  index,
guint  length 
)

Removes the given number of bytes starting at the given index from a ByteArray.

The following elements are moved to close the gap.

Since glibmm 2.4:
Parameters
indexThe index of the first byte to remove.
lengthThe number of bytes to remove.
Returns
The ByteArray.

◆ set_size()

Glib::RefPtr< ByteArray > Glib::ByteArray::set_size ( guint  length)

Sets the size of the ByteArray, expanding it if necessary.

Parameters
lengthThe new size of the ByteArray.
Returns
The ByteArray.

◆ size()

guint Glib::ByteArray::size ( ) const

Gets the size of the byte array.

Returns
The size.
Since glibmm 2.36:

◆ sort()

void Glib::ByteArray::sort ( const SlotCompare slot)

Like g_byte_array_sort(), but the comparison function takes an extra user data argument.

Parameters
slotComparison function.

◆ unreference()

void Glib::ByteArray::unreference ( ) const

Decrement the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

Friends And Related Symbol Documentation

◆ wrap()

Glib::RefPtr< Glib::ByteArray > wrap ( GByteArray object,
bool  take_copy = false 
)
related

A Glib::wrap() method for this object.

Parameters
objectThe C instance.
take_copyFalse if the result should take ownership of the C instance. True if it should take a new copy or ref.
Returns
A C++ instance that wraps this C instance.
