```
Set a custom handler for warnings and errors. This is mostly used for piping the warnings and errors to a file behind the scenes. If you want to filter warnings and errors, you should use a WarningsGuard. If you want to change how warnings and errors are reported to the user, you should set a ErrorManager on the Compiler. An ErrorManager is intended to summarize the errors for a single compile job.

setInferTypes
```
public void setInferTypes(boolean enable)
```
If true, enables type inference. If checkTypes is enabled, this flag has no effect.

getInferTypes
```
public boolean getInferTypes()
```
Gets the inferTypes flag. Note that if checkTypes is enabled, this flag is ignored when configuring the compiler.

setNewTypeInference

```
public void setAssumeStrictThis(boolean enable)
```

public boolean assumeClosuresOnlyCaptureReferences()
```
Returns:

Whether assumeClosuresOnlyCaptureReferences is set.

setAssumeClosuresOnlyCaptureReferences
```
public void setAssumeClosuresOnlyCaptureReferences(boolean enable)
```
Whether to assume closures capture only what they reference. This allows more aggressive function inlining.

setPropertyInvalidationErrors

public void setPropertyInvalidationErrors(java.util.Map<java.lang.String,CheckLevel> propertyInvalidationErrors)

Sets the list of properties that we report property invalidation errors for.

setIdeMode
```
@Deprecated
public void setIdeMode(boolean ideMode)
```
Deprecated. Some "IDE" clients will need some of these options but not others. Consider calling setChecksOnly, setAllowRecompilation, etc, explicitly, instead of calling this method which does a variety of different things.
Configures the compiler for use as an IDE backend. In this mode:
- No optimization passes will run.
- The last time custom passes are invoked is CustomPassExecutionTime.BEFORE_OPTIMIZATIONS
- The compiler will always try to process all inputs fully, even if it encounters errors.
- The compiler may record more information than is strictly needed for codegen.

isParseJsDocDocumentation
```
public Config.JsDocParsing isParseJsDocDocumentation()
```
Checks JSDoc documentation will be parsed.

Returns:

True when JSDoc documentation will be parsed, false if not.

setSkipNonTranspilationPasses
```
public void setSkipNonTranspilationPasses(boolean skipNonTranspilationPasses)
