Superclasses:

Build context during code generation

expand all in page

Description

The code generator creates an object of this class to facilitate access to thebuild context. The build context encapsulates the settings used by the code generator including:

  • Target language

  • Code generation target

  • Target hardware

  • Build toolchain

Usecoder.BuildConfigmethods in the methods that you write for thecoder.ExternalDependencyclass.

Construction

The code generator creates objects of this class.

方法

getHardwareImplementation Get handle of copy of hardware implementation object
getStdLibInfo Get standard library information
getTargetLang Get target code generation language
GetToolChainInfo 返回工具链信息对象的副本
isCodeGenTarget Determine if build configuration represents specified target
isMatlabHostTarget 确定硬件实现对象目标是否为MATLABhost computer

Copy Semantics

Value. To learn how value classes affect copy operations, seeCopying Objects（MATLAB）。

This example shows how to usecoder.BuildConfigmethods to access the build context incoder.ExternalDependency方法。在此示例中，您使用：

  • coder.buildconfig.ismatlabhosttargetto verify that the code generation target is the MATLAB®host. If the host is not MATLAB report an error.

  • coder.BuildConfig.getStdLibInfoto get the link-time and run-time library file extensions. Use this information to update the build information.

Write a class definition file for an external library that contains the functionadder.
