roSystemLog

This object enables the application to receive events that are intended for reporting errors and trends, rather than for

triggering a response to a user action.

roSystemLog requires specific design patterns in your BrightScript application:

• Use one roMessagePort throughout the application (instead of creating a new roMessagePort for each screen).

• Create one roSystemLog instance at startup that remains for the entire lifetime of the application.

• Pass the global roMessagePort mentioned above to SetMessagePort() on the roSystemLog component.

• Enable the desired log types using EnableType().

This object is created with no parameters:

CreateObject("roSystemLog")

Interfaces: ifStreamSend, ifSystemLog

The ifStreamSend interface provides the following:

• SetSendEol(eol_sequence As String) As Void: Sets the EOL sequence when writing to the stream.

• SendByte(byte As Integer) As Void: Writes the specified byte to the stream.

• SendLine(string As String) As Void: Writes the specified characters to the stream followed by the

current EOL sequence.

• SendBlock(a As Dynamic) As Void: Writes the specified characters to the stream. This method can support

either a string or an roByteArray. If the block is a string, any null bytes will terminate the block.

• Flush()
