CPPCodeGenerator class
(Shortest import: from brian2.codegen.generators import CPPCodeGenerator)
- class brian2.codegen.generators.cpp_generator.CPPCodeGenerator(*args, **kwds)[source]
Bases:
CodeGenerator
C++ language
C++ code templates should provide Jinja2 macros with the following names:
main
The main loop.
support_code
The support code (function definitions, etc.), compiled in a separate file.
For user-defined functions, there are two keys to provide:
support_code
The function definition which will be added to the support code.
hashdefine_code
The
#define
code added to the main loop.
See
TimedArray
for an example of these keys.Attributes
Methods
A dictionary of values that is made available to the templated.
get_array_name
(var[, access_data])Get a globally unique name for a
ArrayVariable
.translate_expression
(expr)Translate the given expression string into a string in the target language, returns a string.
translate_one_statement_sequence
(statements)translate_statement
(statement)Translate a single line
Statement
into the target language, returns a string.translate_statement_sequence
(sc_statements, ...)Translate a sequence of
Statement
into the target language, taking care to declare variables, etc.translate_to_declarations

(write)Details
- flush_denormals
- restrict
- determine_keywords()[source]
A dictionary of values that is made available to the templated. This is used for example by the
CPPCodeGenerator
to set up all the supporting code
- static get_array_name(var, access_data=True)[source]
Get a globally unique name for a
ArrayVariable
.
- translate_expression(expr)[source]
Translate the given expression string into a string in the target language, returns a string.
- translate_statement(statement)[source]
Translate a single line
Statement
into the target language, returns a string.
- translate_statement_sequence(sc_statements, ve_statements)[source]
Translate a sequence of
Statement
into the target language, taking care to declare variables, etc. if necessary.Returns a tuple
(scalar_code, vector_code, kwds)
wherescalar_code
is a list of the lines of code executed before the inner loop,vector_code
is a list of the lines of code in the inner loop, andkwds
is a dictionary of values that is made available to the template.
