def gencpp._escape_string (   s)
private

Definition at line 96 of file __init__.py.

def gencpp.cpp_message_declarations (   name_prefix,
  msg 
)
Return the different possible C++ declarations for a message given the message itself.

@param name_prefix: The C++ prefix to be prepended to the name, e.g. "std_msgs::"
@type name_prefix: str
@param msg: The message type
@type msg: str
@return: A tuple of 3 different names.  cpp_message_decelarations("std_msgs::", "String") returns the tuple
    ("std_msgs::String_", "std_msgs::String_<ContainerAllocator>", "std_msgs::String")
@rtype: str

Definition at line 119 of file __init__.py.

def gencpp.default_value (   type_)
Return the value to initialize a message member with.

0 for integer types, 0.0 for floating point, false for bool,
empty string for everything else

@param type_: The type
@type type_: str

Definition at line 171 of file __init__.py.

def gencpp.escape_message_definition (   definition)

Definition at line 102 of file __init__.py.

def gencpp.escape_string (   str_)

Definition at line 211 of file __init__.py.

def gencpp.generate_fixed_length_assigns (   spec,
  container_gets_allocator,
  cpp_name_prefix 
)
Initialize any fixed-length arrays.

@param s: The stream to write to
@type s: stream
@param spec: The message spec
@type spec: genmsg.msgs.MsgSpec
@param container_gets_allocator: Whether or not a container type (whether it's another message, a vector, array or string)
    should have the allocator passed to its constructor.  Assumes the allocator is named _alloc.
@type container_gets_allocator: bool
@param cpp_name_prefix: The C++ prefix to use when referring to the message, e.g. "std_msgs::"
@type cpp_name_prefix: str

Definition at line 218 of file __init__.py.

def gencpp.generate_initializer_list (   spec,
  container_gets_allocator 
)
Write the initializer list for a constructor.

@param s: The stream to write to
@type s: stream
@param spec: The message spec
@type spec: genmsg.msgs.MsgSpec
@param container_gets_allocator: Whether or not a container type (whether it's another message, a vector, array or string)
    should have the allocator passed to its constructor.  Assumes the allocator is named _alloc.
@type container_gets_allocator: bool

Definition at line 251 of file __init__.py.

def gencpp.is_fixed_length (   spec,
  msg_context,
  includepath 
)
Return whether or not the message is fixed-length.

@param spec: The message spec
@type spec: genmsg.msgs.MsgSpec
@param package: The package of the
@type package: str

Definition at line 139 of file __init__.py.

def gencpp.msg_type_to_cpp (   type_)
Convert a message type into the C++ declaration for that type.

Example message types: uint32, std_msgs/String.
Example C++ types: uint32_t, std_msgs::String_<ContainerAllocator>

@param type_: The message type
@type type_: str
@return: The C++ declaration
@rtype: str

Definition at line 61 of file __init__.py.

def gencpp.takes_allocator (   type_)
Return whether or not a type can take an allocator in its constructor.

False for all builtin types except string.
True for all others.

@param type_: The type
@type: str

Definition at line 195 of file __init__.py.
