- com.google.template.soy.parsepasses.contextautoesc.ContextualAutoescaper

```
public final class ContextualAutoescaper
extends Object
```
Inserts directives into print commands by looking at the context in which a print appears, and derives templates and rewrites calls so that each template is entered only in contexts consistent with its escaping conventions. E.g. it will rewrite to

Modifier and Type	Method and Description
`com.google.common.collect.ImmutableList<SlicedRawTextNode>`	`getSlicedRawTextNodes()` Maps ranges of text-nodes to contexts so that later parse passes can add attributes or elements.
`Context`	`getTemplateEndContext(String templateName)` Null if no typing has been done for the named template, or otherwise the context after a call to the named template.
`List<TemplateNode>`	`rewrite(SoyFileSetNode fileSet, TemplateRegistry registry, ErrorReporter errorReporter)` Rewrites the given Soy files so that dynamic output is properly escaped according to the context in which it appears.

public ContextualAutoescaper(Iterable<String> autoescapeCancellingDirectives,
                     Map<String,SanitizedContent.ContentKind> sanitizedContentOperators)
```
    Parameters:
    autoescapeCancellingDirectives - The Soy directives that cancel autoescaping (see SoyPrintDirective.shouldCancelAutoescape()).
    sanitizedContentOperators - Maps print directive names to the content kinds they consume and produce.

```
public List<TemplateNode> rewrite(SoyFileSetNode fileSet,
                         TemplateRegistry registry,
                         ErrorReporter errorReporter)
```
    Rewrites the given Soy files so that dynamic output is properly escaped according to the context in which it appears.
    
    Parameters:
    fileSet - Modified in place.
    
    Returns:
    Extra templates which were derived from templates under fileSet and which must be compiled with fileSet to produce a correct output. See DerivedTemplateUtils for an explanation of these.
  - getTemplateEndContext
```
public Context getTemplateEndContext(String templateName)
```
    Null if no typing has been done for the named template, or otherwise the context after a call to the named template. Since we derive templates by start context at the call site, there is no start context parameter.
    
    Parameters:
    templateName - A qualified template name.
  - getSlicedRawTextNodes
```
public com.google.common.collect.ImmutableList<SlicedRawTextNode> getSlicedRawTextNodes()
```
    Maps ranges of text-nodes to contexts so that later parse passes can add attributes or elements.
