Method Detail

setValueIfAttributeDefined

public static void setValueIfAttributeDefined(org.springframework.beans.factory.support.BeanDefinitionBuilder builder,
                                              org.w3c.dom.Element element,
                                              java.lang.String attributeName,
                                              java.lang.String propertyName)

Populates the specified bean definition property with the value of the attribute whose name is provided if that attribute is defined in the given element.

Parameters:

beanDefinition - the bean definition to be configured

element - the XML element where the attribute should be defined

attributeName - the name of the attribute whose value will be used to populate the property

propertyName - the name of the property to be populated

setValueIfAttributeDefined

public static void setValueIfAttributeDefined(org.springframework.beans.factory.support.BeanDefinitionBuilder builder,
                                              org.w3c.dom.Element element,
                                              java.lang.String attributeName)

Populates the bean definition property corresponding to the specified attributeName with the value of that attribute if it is defined in the given element.

The property name will be the camel-case equivalent of the lower case hyphen separated attribute (e.g. the "foo-bar" attribute would match the "fooBar" property).

Parameters:

beanDefinition - - the bean definition to be configured

element - - the XML element where the attribute should be defined

attributeName - - the name of the attribute whose value will be set on the property

Conventions.attributeNameToPropertyName(String)

setReferenceIfAttributeDefined

public static void setReferenceIfAttributeDefined(org.springframework.beans.factory.support.BeanDefinitionBuilder builder,
                                                  org.w3c.dom.Element element,
                                                  java.lang.String attributeName,
                                                  java.lang.String propertyName)

Populates the specified bean definition property with the reference to a bean. The bean reference is identified by the value from the attribute whose name is provided if that attribute is defined in the given element.

Parameters:

beanDefinition - the bean definition to be configured

element - the XML element where the attribute should be defined

attributeName - the name of the attribute whose value will be used as a bean reference to populate the property

propertyName - the name of the property to be populated

setReferenceIfAttributeDefined

public static void setReferenceIfAttributeDefined(org.springframework.beans.factory.support.BeanDefinitionBuilder builder,
                                                  org.w3c.dom.Element element,
                                                  java.lang.String attributeName)

Populates the bean definition property corresponding to the specified attributeName with the reference to a bean identified by the value of that attribute if the attribute is defined in the given element.

The property name will be the camel-case equivalent of the lower case hyphen separated attribute (e.g. the "foo-bar" attribute would match the "fooBar" property).

Parameters:

beanDefinition - - the bean definition to be configured

element - - the XML element where the attribute should be defined

attributeName - - the name of the attribute whose value will be used as a bean reference to populate the property

createElementDescription

public static java.lang.String createElementDescription(org.w3c.dom.Element element)

Provides a user friendly description of an element based on its node name and, if available, its "id" attribute value. This is useful for creating error messages from within bean definition parsers.

configurePollerMetadata

public static void configurePollerMetadata(org.w3c.dom.Element pollerElement,
                                           org.springframework.beans.factory.support.BeanDefinitionBuilder targetBuilder,
                                           org.springframework.beans.factory.xml.ParserContext parserContext)

Parse a "poller" element to provide a reference for the target BeanDefinitionBuilder. If the poller element does not contain a "ref" attribute, this will create and register a PollerMetadata instance and then add it as a property reference of the target builder.

Parameters:

pollerElement - the "poller" element to parse

targetBuilder - the builder that expects the "trigger" property

parserContext - the parserContext for the target builder
