Class EvaluationContextImpl

java.lang.Object

com.mitchellbosecke.pebble.template.EvaluationContextImpl

All Implemented Interfaces:

EvaluationContext

public class EvaluationContextImpl
extends Object
implements EvaluationContext

An evaluation context will store all stateful data that is necessary for the evaluation of a template. Passing the entire state around will assist with thread safety.

EvaluationContextImpl

public EvaluationContextImpl(PebbleTemplateImpl self,
                             boolean strictVariables,
                             Locale locale,
                             ExtensionRegistry extensionRegistry,
                             PebbleCache<CacheKey,Object> tagCache,
                             ExecutorService executorService,
                             List<PebbleTemplateImpl> importedTemplates,
                             Map<String,PebbleTemplateImpl> namedImportedTemplates,
                             ScopeChain scopeChain,
                             Hierarchy hierarchy,
                             EvaluationOptions evaluationOptions)

Constructor used to provide all final variables.

Parameters:

self - The template implementation

strictVariables - Whether strict variables is to be used

locale - The locale of the template

extensionRegistry - The extension registry

executorService - The optional executor service

scopeChain - The scope chain

hierarchy - The inheritance chain

tagCache - The cache used by the "cache" tag

Method Detail

shallowCopyWithoutInheritanceChain

public EvaluationContextImpl shallowCopyWithoutInheritanceChain(PebbleTemplateImpl self)

Makes an exact copy of the evaluation context EXCEPT for the inheritance chain. This is necessary for the "include" tag.

Parameters:

self - The template implementation

Returns:

A copy of the evaluation context

threadSafeCopy

public EvaluationContextImpl threadSafeCopy(PebbleTemplateImpl self)

Makes a "snapshot" of the evaluation context. The scopeChain object will be a deep copy and the imported templates will be a new list. This is used for the "parallel" tag.

Parameters:

self - The template implementation

Returns:

A copy of the evaluation context

getNamedImportedTemplate

public PebbleTemplateImpl getNamedImportedTemplate(String alias)

Returns the named imported template.

Returns:

the named imported template.

addNamedImportedTemplates

public void addNamedImportedTemplates(String alias,
                                      PebbleTemplateImpl template)

isStrictVariables

public boolean isStrictVariables()

Returns whether or not this template is being evaluated in "strict templates" mode

Specified by:

isStrictVariables in interface EvaluationContext

getExtensionRegistry

public ExtensionRegistry getExtensionRegistry()

Returns the extension registry used to access all of the tests/filters/functions

Returns:

The extension registry

getExecutorService

public ExecutorService getExecutorService()

getTagCache

public PebbleCache<CacheKey,Object> getTagCache()

Returns the cache used for the "cache" tag

Returns:

The cache used for the "cache" tag

getScopeChain

public ScopeChain getScopeChain()

Returns the scope chain data structure that allows variables to be added/removed from the current scope and retrieved from the nearest visible scopes.

Returns:

The scope chain.

getHierarchy

public Hierarchy getHierarchy()
