Method Detail

setChannelAttributeName

public void setChannelAttributeName(java.lang.String channelAttributeName)

getPayloadExpression

public java.lang.String getPayloadExpression(java.lang.reflect.Method method)

Returns the expression string to be evaluated for creating the Message payload.

getHeaderExpressions

public java.lang.String[] getHeaderExpressions(java.lang.reflect.Method method)

Returns the array of expression strings to be evaluated for any headers that should be set on the published Message.

getMethodNameVariableName

public java.lang.String getMethodNameVariableName(java.lang.reflect.Method method)

Returns the variable name to be associated with the intercepted method's name.

getArgumentVariableNames

public java.lang.String[] getArgumentVariableNames(java.lang.reflect.Method method)

Returns the variable names to be associated with the intercepted method invocation's argument array.

getArgumentMapVariableName

public java.lang.String getArgumentMapVariableName(java.lang.reflect.Method method)

Returns the variable name to use in the evaluation context for the Map of arguments. The keys in this map will be determined by the result of the #getArgumentNames(Method) method.

getReturnValueVariableName

public java.lang.String getReturnValueVariableName(java.lang.reflect.Method method)

Returns the variable name to use in the evaluation context for any return value resulting from the method invocation.

getExceptionVariableName

public java.lang.String getExceptionVariableName(java.lang.reflect.Method method)
