Enum Constant Summary

Enum Constants
Enum Constant and Description
`BEAN_IDENTIFIER_INDEX_OPTIMIZATION` This optimization is used to reduce the HTTP session replication overhead.
`CONCURRENT_DEPLOYMENT` Indicates whether ConcurrentDeployer and ConcurrentValidator should be enabled.
`DISABLE_XML_VALIDATION` XML descriptor validation is enabled by default.
`EXECUTOR_THREAD_POOL_DEBUG` If set to true, debug timing information is printed to the standard output.
`EXECUTOR_THREAD_POOL_KEEP_ALIVE_TIME` Keep-alive time in seconds.
`EXECUTOR_THREAD_POOL_SIZE` The number of threads to be used for bean loading and deployment.
`EXECUTOR_THREAD_POOL_TYPE` The type of the thread pool.
`INJECTABLE_REFERENCE_OPTIMIZATION` For certain combinations of scopes, the container is permitted to optimize an injectable reference lookup.
`NON_PORTABLE_MODE` Allows an integrator to enable the non-portable mode.
`PRELOADER_THREAD_POOL_SIZE` The number of threads used by ContainerLifecycleEventPreloader.
`PROXY_DUMP` For debug purposes, it's possible to dump the generated bytecode of proxies and subclasses.
`PROXY_INSTANTIATOR` Allows `ProxyInstantiator` to be selected explicitly.
`PROXY_UNSAFE` Deprecated. this option is deprecated. RELAXED_CONSTRUCTION should be used instead
`RELAXED_CONSTRUCTION` Weld supports a non-standard workaround to be able to create client proxies for Java types that cannot be proxied by the container, using non-portable JVM APIs.
`RESOLUTION_CACHE_SIZE` Weld caches already resolved injection points in order to resolve them faster in the future.

- Enum Constant Detail
  - CONCURRENT_DEPLOYMENT
```
public static final ConfigurationKey CONCURRENT_DEPLOYMENT
```
    Indicates whether ConcurrentDeployer and ConcurrentValidator should be enabled. If enabled, ConcurrentDeployer and ConcurrentValidator execute their subtasks using ExecutorServices which can be configured separately. Otherwise, single-threaded version of Deployer and Validator are used. By default, concurrent deployment is enabled.
  - PRELOADER_THREAD_POOL_SIZE
```
public static final ConfigurationKey PRELOADER_THREAD_POOL_SIZE
```
    The number of threads used by ContainerLifecycleEventPreloader. The ContainerLifecycleEventPreloader allows observer methods for container lifecycle events to be resolved upfront while the deployment is waiting for classloader or reflection API. ContainerLifecycleEventPreloader has its own thread pool whose size is configured by this property. If set to 0, ContainerLifecycleEventPreloader is not installed. If not specified, the value is set to Math.max(1, Runtime.getRuntime().availableProcessors() - 1)).
  - NON_PORTABLE_MODE
```
public static final ConfigurationKey NON_PORTABLE_MODE
```
    Allows an integrator to enable the non-portable mode. Non-portable mode is suggested by the specification to overcome problems with legacy applications not using CDI SPI properly. The non-portable mode is disabled by default.
  - EXECUTOR_THREAD_POOL_SIZE
```
public static final ConfigurationKey EXECUTOR_THREAD_POOL_SIZE
```
    The number of threads to be used for bean loading and deployment.
  - EXECUTOR_THREAD_POOL_DEBUG
```
public static final ConfigurationKey EXECUTOR_THREAD_POOL_DEBUG
```
    If set to true, debug timing information is printed to the standard output.
  - EXECUTOR_THREAD_POOL_TYPE
```
public static final ConfigurationKey EXECUTOR_THREAD_POOL_TYPE
```
    The type of the thread pool. Possible values are: FIXED, FIXED_TIMEOUT, NONE, SINGLE_THREAD.
  - EXECUTOR_THREAD_POOL_KEEP_ALIVE_TIME
```
public static final ConfigurationKey EXECUTOR_THREAD_POOL_KEEP_ALIVE_TIME
```
    Keep-alive time in seconds. Passed to the constructor of the ThreadPoolExecutor class, maximum time that excess idle threads will wait for new tasks before terminating.
  - RESOLUTION_CACHE_SIZE
```
public static final ConfigurationKey RESOLUTION_CACHE_SIZE
```
    Weld caches already resolved injection points in order to resolve them faster in the future. There exists a separate type safe resolver for beans, decorators, disposers, interceptors and observers. Each of them stores resolved injection points in its cache, which maximum size is bounded by a default value (common to all of them).

  - PROXY_DUMP
```
public static final ConfigurationKey PROXY_DUMP
```
    For debug purposes, it's possible to dump the generated bytecode of proxies and subclasses.
  - RELAXED_CONSTRUCTION
```
public static final ConfigurationKey RELAXED_CONSTRUCTION
```
    Weld supports a non-standard workaround to be able to create client proxies for Java types that cannot be proxied by the container, using non-portable JVM APIs.
  - PROXY_INSTANTIATOR
```
public static final ConfigurationKey PROXY_INSTANTIATOR
```
    Allows ProxyInstantiator to be selected explicitly. This is only intended for testing purposes and should never be set by an application.
  - PROXY_UNSAFE
```
public static final ConfigurationKey PROXY_UNSAFE
```
    Deprecated. this option is deprecated. RELAXED_CONSTRUCTION should be used instead
    
    Weld supports a non-standard workaround to be able to create client proxies for Java types that cannot be proxied by the container, using non-portable JVM APIs.
  - DISABLE_XML_VALIDATION
```
public static final ConfigurationKey DISABLE_XML_VALIDATION
```
    XML descriptor validation is enabled by default.
  - INJECTABLE_REFERENCE_OPTIMIZATION
```
public static final ConfigurationKey INJECTABLE_REFERENCE_OPTIMIZATION
```
    For certain combinations of scopes, the container is permitted to optimize an injectable reference lookup. The optimization is disabled by default as it does not match the AlterableContext contract.
  - BEAN_IDENTIFIER_INDEX_OPTIMIZATION
```
public static final ConfigurationKey BEAN_IDENTIFIER_INDEX_OPTIMIZATION
```
    This optimization is used to reduce the HTTP session replication overhead. However, the inconsistency detection mechanism may cause problems in some development environments.
- Method Detail
  - values
```
public static ConfigurationKey[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```

    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ConfigurationKey valueOf(java.lang.String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.

    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
  - get
```
public java.lang.String get()
```
    Returns:
    
    the string representation of the key
  - getDefaultValue
```
public java.lang.Object getDefaultValue()
```
    Returns:
    
    the default value
  - isValidValue
```
public boolean isValidValue(java.lang.Object value)
```
    Parameters:
    
    value -
    
    Returns:
    
    true if the given value corresponds to the type of the default value, false otherwise
  - isValidValueType
```
public boolean isValidValueType(java.lang.Class<?> valueType)
```
    Parameters:
    
    valueType -
    
    Returns:
    
    true if the given value type corresponds to the type of the default value, false otherwise
  - convertValue
```
public java.lang.Object convertValue(java.lang.String value)
```
    Parameters:
    
    value -
    
    Returns:
    
    the converted value
  - isValueTypeSupported
```
public static boolean isValueTypeSupported(java.lang.Class<?> valueType)
```
    Parameters:
    
    valueType -
    
    Returns:
    
    true if the given value type is supported, false otherwise
