class cpp_delegate.context.RemoteContext(stream, cpp_ast_json, namespace='')

Bases: cpp_delegate.context.Context, cpp_delegate.dir_mixin.DirMixIn

This class provides access to public variables and fields within a remote context (i.e., namespace).

Variables and fields are accessible as Python attributes, allowing, for example, tab completion in IPython.

Parameters:

• stream (serial.Serial) – A serial connection to the remote device.
• cpp_ast_json (dict) – A JSON-serializable C++ abstract syntax tree, as parsed by clang_helpers.clang_ast.parse_cpp_ast(…, format=’json’).
• namespace (str, optional) –

  A namespace specifier (e.g., "foo::bar") indicating the namespace to expose.

  A value of "" corresponds to the top-level namespace.

.<remote variable/field>

An attribute corresponding to each public variable or field within the remote context namespace.

_address_of(label)

Parameters:label (str) – Name/label of variable or field in remote context. Returns:Address in memory of specified variable or field in remote context. Return type:int

_mem_read(address, size)

Parameters:

• address (int) – Memory address in remote context.
• size (int) – Number of bytes to read.

Returns:

Array of data read from remote context.

Return type:

np.array(dtype=’uint8’)

_read_attribute()

_mem_write(address, data)

Write data to specified address in remote context.

Parameters:

• address (int) – Memory address in remote context.
• data (numpy.array-like) – Array or :module:`numpy` data type.

_write_attribute()

_read_attribute(attr, *args)

Parameters:

• attr (str) – Name of attribute in remote context.
• default (object, optional) – Default return value.

Returns:

Value of specified attribute in remote context.

If type is not supported (i.e., not a plain old data type), default is returned (if specified).

Return type:

type of attr

_read_attributes()

Returns:Value of each attribute in remote context.

For each attribute, if type is not supported (i.e., not a plain old data type), value is set to None.

Return type:dict

_write_attribute()

_write_attribute(attr, value)

Parameters:

• attr (str) – Name of attribute in remote context.
• value (type of attr) – Value to set for specified attribute in remote context.

Raises:

TypeError – If attribute type is not supported (i.e., not a plain old data type).
