Class Details

class Cattle.Buffer(**kwargs)

Bases:

GObject.Object

Abstract:

No

Structure:

Cattle.BufferClass

Opaque data structure representing a memory buffer. It should never be accessed directly.

classmethod new(size)

Parameters:

size (int) – size of the buffer

Returns:

a new Cattle.Buffer

Return type:

Cattle.Buffer

Create and initialize a new memory buffer.

get_size()

Returns:

the size of the memory buffer

Return type:

int

Get the size of the memory buffer.

get_value(position)

Parameters:

position (int) – offset inside the memory buffer

Returns:

the value of the selected byte.

Return type:

int

Get the value of a specific byte inside the memory buffer.

The value of position must be smaller than the size of the memory buffer, as returned by Cattle.Buffer.get_size().

set_contents(contents)

Parameters:

contents ([int]) – data to copy inside the memory buffer

Set the contents of the memory buffer.

This method exists mainly for bindings; Cattle.Buffer.set_contents() is more convenient when writing C code.

set_value(position, value)

Parameters:

• position (int) – offset inside the memory buffer

• value (int) – new value

Set the value of a specific byte inside the memory buffer.

The value of position must be smaller than the size of the memory buffer, as returned by Cattle.Buffer.get_size().

Property Details

Cattle.Buffer.props.size

Name:

size

Type:

int

Default Value:

Flags:
