Package org.apache.tika.config.loader

Class LoaderContext

java.lang.Object

org.apache.tika.config.loader.LoaderContext

public class LoaderContext
extends Object

Shared context passed to ComponentLoaders.

Provides access to dependencies and utilities without tight coupling. Component loaders can use this to:

• Access the ClassLoader for SPI loading
• Use the ObjectMapper for JSON deserialization
• Get cross-component dependencies (e.g., EncodingDetector for parsers)
• Instantiate components via the shared ComponentInstantiator

getObjectMapper

public com.fasterxml.jackson.databind.ObjectMapper getObjectMapper()

get

public <T> T get(Class<T> componentClass)
          throws TikaConfigException

Get a dependency by class type. Uses lazy loading to avoid circular dependencies.

Parameters:

componentClass - the component class to get

Returns:

the component instance

Throws:

TikaConfigException - if loading fails

getEncodingDetector

public EncodingDetector getEncodingDetector()
                                     throws TikaConfigException

Get the EncodingDetector for injection into parsers.

Returns:

the encoding detector

Throws:

TikaConfigException - if loading fails

getRenderer

public Renderer getRenderer()
                     throws TikaConfigException

Get the Renderer for injection into rendering parsers.

Returns:

the renderer

Throws:

TikaConfigException - if loading fails

instantiate

public <T> T instantiate(String name,
 com.fasterxml.jackson.databind.JsonNode configNode)
                  throws TikaConfigException

Instantiate a component by name and config.

Parameters:

name - the component name (friendly name or FQCN)

configNode - the JSON configuration for the component

Returns:

the instantiated component

Throws:

TikaConfigException - if instantiation fails
