Class JvConfiguration

java.lang.Object
  org.javalid.core.config.JvConfiguration

public class JvConfiguration
extends java.lang.Object

This class is responsible for loading the xml configuration file(s) and create a valid configuration from it. The loading process is initialized directly from the constructor, hence only 1 instance of this class is needed normally.

The class loads the core configuration xml file only, any config files related to extensionsMap are loaded by the extensionsMap themselves, this class only kicks them off in that case.

Constructor Detail

JvConfiguration

public JvConfiguration(java.lang.String xmlConfigFile,
                       AnnotationValidator validator)
                throws JavalidException

Construct this configuration by xmlConfigFile and reference to the validator this config is for.

Parameters:

xmlConfigFile - The configuration file

validator - The validator

Throws:

JavalidException - Raised if loading fails

Method Detail

init

protected void init(java.lang.String xmlConfigFile)
             throws JavalidException

Throws:

JavalidException

getImplementationClassForAnnotation

public JavalidValidator getImplementationClassForAnnotation(java.lang.String className)
                                                     throws JavalidException

Checks the map containing the annotation implementations supported by the framework. If found returns the implementation class, ready to use. If not found raises an exception.

Parameters:

className - Fully qualified annotation class name to check

Returns:

JvValidator ready for use

Throws:

JavalidException - Raised if no implementation class was found

isImplementationClassAvailableForAnnotation

public boolean isImplementationClassAvailableForAnnotation(java.lang.String className)

Returns true if for given fully qualified classname of an annotation, a validator is available

Parameters:

className - The fully qualified classname of an annotation

Returns:

True if found, false otherwise.

isPluralAnnotationSupported

public boolean isPluralAnnotationSupported(java.lang.String className)

Returns true if given plural annotation is supported.

Parameters:

className - The annotation classname to check

Returns:

True if supported, false otherwise.

Since:

1.1

lookupBean

public java.lang.Object lookupBean(java.lang.String beanLookupName)

Locates given beanName and returns bean instance if found. If not found, raises a JvLookupFailedException for invalid lookupType raises JvException.

Parameters:

beanLookupName - The beanName to lookup

Returns:

Bean instance if found, JvLookupException if not found.

Since:

1.1

isExtensionLoaded

public boolean isExtensionLoaded(java.lang.String nameExtension)

Returns true if an extension under given name is loaded, false otherwise.

Parameters:

nameExtension - The name of the extension

Returns:

Returns true if an extension under given name is loaded, false otherwise.

Since:

1.1

getExtension

public JavalidExtension getExtension(java.lang.String nameExtension)

Returns the extension for given name if found, null otherwise.

Parameters:

nameExtension - The name of the extension.

Returns:

The extension if found or null

Since:

1.1

callExtensionsBeforeValidation

public void callExtensionsBeforeValidation(JvConfigurationWrapper wrapper)

Calls the beforeValidation(..) method on each extension

Parameters:

wrapper - The config wrapper

Since:

1.1

callExtensionsAfterValidation

public void callExtensionsAfterValidation(JvConfigurationWrapper wrapper)

Calls the afterValidation(..) method on each extension

Parameters:

wrapper - The config wrapper

Since:

1.1

getConfigWrapper

public JvConfigurationWrapper getConfigWrapper()

Gets a new configuration wrapper for this configuration. Use this to pass around to non-core framework code (such as validation implementations). TODO: Consider creating it here once and return that one instead?

Returns:

Configuration wrapper

isCheckForProxy

public boolean isCheckForProxy()

Return true if classes should check the parent class for an annotation (method annotations e.g) if not found on the current method/class.

Returns:

True if classes should check parent class for an annotation as well if not found on current class

isCheckAnnotationsOnMethods

public boolean isCheckAnnotationsOnMethods()

Returns true if annotations must be checked on methods, if false fields must be used.

Returns:

True if annotations must be checked on methods, if false fields must be used.

getProxyRecognizers

public java.lang.String[] getProxyRecognizers()

Returns all names to recognize a classname as a proxied object (only valid if isCheckForProxy() returns true, else this returns null).

Returns:

Array with names to recognize proxies from (or null if checkForProxy = false).

getELContext

public javax.el.ELContext getELContext()

Returns the context that is used by the framework. The context is created anew each time you call this method (as it cannot be shared among multiple threads!). The resolver returned depends on several settings: 1) By default the framework's own context is returned (if jsflookup is disabled) 2) If jsflookup is enabled, returns a jsf enabled context, topped by the frameworks resolver (JaValid's resolver has precedence in the chain). Also works for JSF 1.1, which is topped by a custom resolver and then internally falling back to its ValueBinding's and that...

Returns:

Current context used by the framework

Since:

1.1

getExpressionFactory

public javax.el.ExpressionFactory getExpressionFactory()

Returns a new ExpressionFactory to use

Returns:

ExpressionFactory to use.

Since:

1.1
