MethodInfo

public MethodInfo(org.apache.camel.CamelContext camelContext,
                  Class<?> type,
                  Method method,
                  List<org.apache.camel.component.bean.ParameterInfo> parameters,
                  List<org.apache.camel.component.bean.ParameterInfo> bodyParameters,
                  boolean hasCustomAnnotation,
                  boolean hasHandlerAnnotation)

Method Detail

toString

public String toString()

Overrides:

toString in class Object

setErrorHandler

public void setErrorHandler(org.apache.camel.Processor errorHandler)

For fine grained error handling for outputs of this EIP. The base error handler is used as base and then cloned for each output processor. This is used internally only by Camel - not for end users.

createMethodInvocation

public MethodInvocation createMethodInvocation(Object pojo,
                                               boolean hasParameters,
                                               org.apache.camel.Exchange exchange)

getType

public Class<?> getType()

getMethod

public Method getMethod()

getPattern

public org.apache.camel.ExchangePattern getPattern()

Returns the ExchangePattern that should be used when invoking this method. This value defaults to ExchangePattern.InOut unless some Pattern annotation is used to override the message exchange pattern.

Returns:

the exchange pattern to use for invoking this method.

getParametersExpression

getBodyParameters

isReturnTypeVoid

public boolean isReturnTypeVoid()

isStaticMethod

public boolean isStaticMethod()

isCovariantWith

public boolean isCovariantWith(MethodInfo method)

Returns true if this method is covariant with the specified method (this method may above or below the specified method in the class hierarchy)
