Method Detail

setChannelAttributeName

public void setChannelAttributeName(String channelAttributeName)

getPayloadExpression

public String getPayloadExpression(Method method)

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

getHeaderExpressions

public Map<String,String> getHeaderExpressions(Method method)

Returns the map of expression strings to be evaluated for any headers that should be set on the published Message. The keys in the Map are header names, the values are the expression strings.

getMethodNameVariableName

public String getMethodNameVariableName(Method method)

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

getArgumentVariableNames

public String[] getArgumentVariableNames(Method method)

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

getArgumentMapVariableName

public String getArgumentMapVariableName(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 getArgumentVariableNames(Method) method.

getReturnValueVariableName

public String getReturnValueVariableName(Method method)

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

getExceptionVariableName

public String getExceptionVariableName(Method method)

Returns the variable name to use in the evaluation context for any exception thrown from the method invocation.

getChannelName

public String getChannelName(Method method)

Returns the channel name to which Messages should be published for this particular method invocation.
