Method Details

getAttribute

public Optional<String> getAttribute(String theKey)

Returns an attribute stored in this message.

Attributes are just a spot for user data of any kind to be added to the message for pasing along the subscription processing pipeline (typically by interceptors). Values will be carried from the beginning to the end.

Note that messages are designed to be passed into queueing systems and serialized as JSON. As a result, only strings are currently allowed as values.

setAttribute

public void setAttribute(String theKey,
 String theValue)

Sets an attribute stored in this message.

Attributes are just a spot for user data of any kind to be added to the message for passing along the subscription processing pipeline (typically by interceptors). Values will be carried from the beginning to the end.

Note that messages are designed to be passed into queueing systems and serialized as JSON. As a result, only strings are currently allowed as values.

Parameters:

theKey - The key (must not be null or blank)

theValue - The value (must not be null)

copyAdditionalPropertiesFrom

public void copyAdditionalPropertiesFrom(BaseResourceMessage theMsg)

Copies any attributes from the given message into this messsage.

See Also:

• setAttribute(String, String)
• getAttribute(String)

getOperationType

public BaseResourceMessage.OperationTypeEnum getOperationType()

Returns the BaseResourceMessage.OperationTypeEnum that is occurring to the Resource of the message

Returns:

the operation type.

setOperationType

public void setOperationType(BaseResourceMessage.OperationTypeEnum theOperationType)

Sets the BaseResourceMessage.OperationTypeEnum occuring to the resource of the message.

Parameters:

theOperationType - The operation type to set.

getTransactionId

@Nullable
public String getTransactionId()

Retrieve the transaction ID related to this message.

Returns:

the transaction ID, or null.

setTransactionId

public void setTransactionId(String theTransactionId)

Adds a transaction ID to this message. This ID can be used for many purposes. For example, performing tracing across asynchronous hooks, tying data together, or downstream logging purposes.

One current internal implementation uses this field to tie back MDM processing results (which are asynchronous) to the original transaction log that caused the MDM processing to occur.

Parameters:

theTransactionId - An ID representing a transaction of relevance to this message.

getMediaType

public String getMediaType()

setMediaType

public void setMediaType(String theMediaType)

getPayloadMessageKey

@Nullable
public String getPayloadMessageKey()

Specified by:

getPayloadMessageKey in interface IHasPayloadMessageKey

Returns:

a message key derived from the payload

setPayloadMessageKey

public void setPayloadMessageKey(String thePayloadMessageKey)

Description copied from interface: IResourceMessage

In cases where the IMessage extracts the message key from the payload, this method can be used to set the message key that will be used. See IMessage.getMessageKey() and IHasPayloadMessageKey.getPayloadMessageKey()

Specified by:

setPayloadMessageKey in interface IResourceMessage

Parameters:

thePayloadMessageKey - the message key that should be used for the message delivering this payload

getAttributes

public Map<String,String> getAttributes()

equals

public boolean equals(Object theO)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
