Method Detail

add

boolean add(ProcessingStatus aProcessingStatus)

Adds a new status event to this one. Different implementations of ProcessingStatus may add the new status to a list or compare it to the existing status and keep only the more severe one.

Parameters:

aProcessingStatus - the new status to add

Returns:

true if this object is updated as a result of this call

add

boolean add(int aSeverity,
          java.lang.String aMessageName,
          java.lang.String aMessageParms)

Adds a new status event to this one. Different implementations of ProcessingStatus may add the new status to a list or compare it to the existing status and keep only the more severe one.

Parameters:

aSeverity - the new severity

aMessageName - the new message identifier (a key to Rule-Message)

aMessageParms - the new message parameters (may be null)

Returns:

true if this object is updated as a result of this call

backoutWorst

void backoutWorst()

clear

void clear()

Clears all status information from this instance.

getLatestMessage

java.lang.String getLatestMessage()

Get the latest status message added to this instance. This may involve looking up a message identifier in Rule-Message. If the message is not found, a message containing the identifier is generated. An error will be registered in Log-Message if logMissingMessages() has been previously called. Note that the latest status will differ from the worst status if the latest is of an equal or lower severity.

Returns:

the status message

getLatestMessageParms

java.lang.String getLatestMessageParms()

Get the latest message parameters added to this status. It will be the same value that was originally passed in via set() or add(). Note that the latest status will differ from the worst status if the latest is of an equal or lower severity.

Returns:

the message parameters

getLatestMessageName

java.lang.String getLatestMessageName()

Get the name of the latest message added to this status. The message name is the part of the ID before the first tab character (or the entire ID if there is no tab). The name is used as the value of the pyMessageName key property to the Rule-Message object.
