# Container Type Definition Format
|
||
|
|
|
||
|
|
This document describes the format of the container definition files contained in this directory.
|
||
|
|
|
||
|
|
### info
|
||
|
|
- `type_name`
|
||
|
|
|
||
|
|
The fully-qualified name of the container type. This is used to match against
|
||
|
|
the names of types contained in an executable's debug information.
|
||
|
|
|
||
|
|
- `ctype`
|
||
|
|
|
||
|
|
A reference to the enum `ContainerTypeEnum` in OI's source code.
|
||
|
|
|
||
|
|
- `header`
|
||
|
|
|
||
|
|
The name of the C++ header file in which this container is defined.
|
||
|
|
|
||
|
|
- `stub_template_params`
|
||
|
|
|
||
|
|
The indexes of template parameters which do not represent types stored within
|
||
|
|
this container. These parameters will not be recursed into and measured by OI.
|
||
|
|
|
||
|
|
- `underlying_container_index`
|
||
|
|
|
||
|
|
Only used for container adapters. Points OI to the template parameter
|
||
|
|
representing the underlying container to be measured.
|
||
|
|
|
||
|
|
### codegen
|
||
|
|
- `decl`
|
||
|
|
|
||
|
|
C++ code for the declaration of a `getSizeType` function for this container.
|
||
|
|
|
||
|
|
- `func`
|
||
|
|
|
||
|
|
C++ code for the definition of a `getSizeType` function for this container.
|
||
|
|
|
||
|
|
|
||
|
|
## Changes introduced with TypeGraph
|
||
|
|
- `typeName` and `matcher` fields have been merged into the single field `type_name`.
|
||
|
|
- `ns` namespace definition is no longer required.
|
||
|
|
- `underlyingContainerIndex` renamed to `underlying_container_index`
|
||
|
|
- The options for measuring / stubbing / removing template parameters have been reworked:
|
||
|
|
- By default all parameters are now measured. This includes the tail parameters in a variadic template.
|
||
|
|
- There is one option to specify template parameters which should not be measured: `stub_template_params`. The type graph code will automatically determine what type of stubbing to apply to each parameter in this list.
|
||
|
|
|
||
|
|
### Deprecated Options
|
||
|
|
- `numTemplateParams`
|
||
|
|
|
||
|
|
The first `numTemplateParams` template parameters for this container represent
|
||
|
|
the types for the data we want to process. If this is not set, use all a
|
||
|
|
container's template parameters. All of a container's parameters will still be
|
||
|
|
enumerated and output in CodeGen, regardless of this setting.
|
||
|
|
|
||
|
|
- `allocatorIndex`
|
||
|
|
|
||
|
|
Index of a template parameter representing an allocator. It will be not be
|
||
|
|
used when CodeGenning this container.
|
||
|
|
|
||
|
|
- `replaceTemplateParamIndex`
|
||
|
|
|
||
|
|
Indexes of template parameters to be stubbed out, i.e. replaced with dummy
|
||
|
|
structs of a given size. Used for custom hashers and comparers.
