public MethodInfo getMethodInfo(Method method)

Returns the MethodInfo for the given method if it exists or null if there is no metadata available for the given method

createMethodInfo

protected MethodInfo createMethodInfo(Class<?> clazz,
                                      Method method)

protected List<Annotation>[] collectParameterAnnotations(Class<?> c,
                                                         Method m)

                           throws AmbiguousMethodCallException

Choose one of the available methods to invoke if we can match the message body to the body parameter

Parameters:

pojo - the bean to invoke a method on

exchange - the message exchange

name - an optional name of the method that must match, use null to indicate all methods

Returns:

the method to invoke or null if no definitive method could be matched

Throws:

AmbiguousMethodCallException - is thrown if cannot choose method due to ambiguity

isValidMethod

protected boolean isValidMethod(Class<?> clazz,
                                Method method)

Validates whether the given method is a valid candidate for Camel Bean Binding.

Parameters:

clazz - the class

method - the method

Returns:

true if valid, false to skip the method

hasMethod

public boolean hasMethod(String methodName)

Do we have a method with the given name.

Shorthand method names for getters is supported, so you can pass in eg 'name' and Camel will can find the real 'getName' method instead.

Parameters:

methodName - the method name

Returns:

true if we have such a method.

hasStaticMethod

public boolean hasStaticMethod(String methodName)

Do we have a static method with the given name.

Shorthand method names for getters is supported, so you can pass in eg 'name' and Camel will can find the real 'getName' method instead.

Parameters:

methodName - the method name

Returns:

true if we have such a static method.

hasPublicConstructors

public boolean hasPublicConstructors()

Returns whether the bean class has any public constructors.

getMethods

public List<MethodInfo> getMethods()

Gets the list of methods sorted by A..Z method name.

Returns:

the methods.
