Interface ValidatorRegistry

All Superinterfaces:

AutoCloseable, Map<ValidatorKey, Validator>, Service, StaticService

public interface ValidatorRegistry
extends Map<ValidatorKey, Validator>, StaticService

Registry that stores and resolves Validator instances for Camel's data type validation mechanism.

The registry maintains two separate caches mirroring the design of TransformerRegistry:

• static cache — holds all validators registered at route startup; no eviction, no size limit. Contains every validator bound to a DataType when the CamelContext starts.
• dynamic cache — holds validators created or registered at runtime (for example, from custom Java code or hot-deployed routes); backed by an LRU cache with a configurable size limit (default 1000 entries) to prevent unbounded growth.

Lookup is performed by resolveValidator(ValidatorKey), which searches both caches using the DataType encoded in the ValidatorKey.

• Validator
• ValidatorKey

Method Details

resolveValidator

@Nullable Validator resolveValidator(ValidatorKey key)

Lookup a Validator in the registry which supports the validation for the data type represented by the key.

Parameters:

key - a key represents the data type

Returns:

Validator if matched, otherwise null

staticSize

int staticSize()

Number of validators in the static registry.

dynamicSize

int dynamicSize()

Number of validators in the dynamic registry

getMaximumCacheSize

int getMaximumCacheSize()

Maximum number of entries to store in the dynamic registry

purge

void purge()

Purges the cache (removes validators from the dynamic cache)

isStatic

boolean isStatic(DataType type)

Whether the given Validator is stored in the static cache

Parameters:

type - the data type

Returns:

true if in static cache, false if not

isDynamic

boolean isDynamic(DataType type)

Whether the given Validator is stored in the dynamic cache

Parameters:

type - the data type

Returns:

true if in dynamic cache, false if not

cleanUp

void cleanUp()

Cleanup the cache (purging stale entries)
