Detailed Description

Reads an AST files chain containing the contents of a translation unit.

The ASTReader class reads bitstreams (produced by the ASTWriter class) containing the serialized representation of a given abstract syntax tree and its supporting data structures. An instance of the ASTReader can be attached to an ASTContext object, which will provide access to the contents of the AST files.

The AST reader provides lazy de-serialization of declarations, as required when traversing the AST. Only those AST nodes that are actually required will be de-serialized.

Member Enumeration Documentation

The result of reading the control block of an AST file, which can fail for various reasons.

Enumerator
Success 

The control block was read successfully. Aside from failures, the AST file is safe to read into the current context.

Failure 

The AST file itself appears corrupted.

Missing 

The AST file was missing.

OutOfDate 

The AST file is out-of-date relative to its input files, and needs to be regenerated.

VersionMismatch 

The AST file was written by a different version of Clang.

ConfigurationMismatch 

The AST file was writtten with a different language/target configuration.

HadErrors 

The AST file has errors.

Definition at line 316 of file ASTReader.h.

Flags that indicate what kind of AST loading failures the client of the AST reader can directly handle.

When a client states that it can handle a particular kind of failure, the AST reader will not emit errors when producing that kind of failure.

Enumerator
ARR_None 

The client can't handle any AST loading failures.

ARR_Missing 

The client can handle an AST file that cannot load because it is missing.

ARR_OutOfDate 

The client can handle an AST file that cannot load because it is out-of-date relative to its input files.

ARR_VersionMismatch 

The client can handle an AST file that cannot load because it was built with a different version of Clang.

ARR_ConfigurationMismatch 

The client can handle an AST file that cannot load because it's compiled configuration doesn't match that of the context it was loaded into.

)

Load the AST file and validate its contents against the given Preprocessor.

Parameters
PPthe preprocessor associated with the context in which this precompiled header will be loaded.
Contextthe AST context that this precompiled header will be loaded into.
PCHContainerOpsthe PCHContainerOperations to use for loading and creating modules.
isysrootIf non-NULL, the system include path specified by the user. This is only used with relocatable PCH files. If non-NULL, a relocatable PCH file will use the default path "/".
DisableValidationIf true, the AST reader will suppress most of its regular consistency checking, allowing the use of precompiled headers that cannot be determined to be compatible.
AllowASTWithCompilerErrorsIf true, the AST reader will accept an AST file the was created out of an AST with compiler errors, otherwise it will reject it.
AllowConfigurationMismatchIf true, the AST reader will not check for configuration differences between the AST file and the invocation.
ValidateSystemInputsIf true, the AST reader will validate system input files in addition to user input files. This is only meaningful if DisableValidation is false.
UseGlobalIndexIf true, the AST reader will try to load and use the global module index.
ReadTimerIf non-null, a timer used to track the time spent deserializing.
