                                                    Class<?> expressionReturnType)

Specified by:

createExpression in interface org.apache.camel.support.language.AnnotationExpressionFactory

Overrides:

createExpression in class org.apache.camel.support.language.DefaultAnnotationExpressionFactory

getResultType

protected Class<?> getResultType(Annotation annotation)

getExpressionNameSpacePrefix

protected org.apache.camel.support.language.NamespacePrefix[] getExpressionNameSpacePrefix(Annotation annotation)

getHeaderName

protected String getHeaderName(Annotation annotation)

Extracts the value of the header method in the Annotation. For backwards compatibility this method will return null if the annotation's method is not found.

Returns:

If the annotation has the method 'header' then the name of the header we want to apply the XPath expression to. Otherwise null will be returned
