Properties

property Fin as %Boolean [ InitialExpression = 1 , Required ];
Property methods: FinDisplayToLogical(), FinGet(), FinIsValid(), FinLogicalToDisplay(), FinNormalize(), FinSet()
property HasMessage as %Boolean [ InitialExpression = 1 ];
Set to false if Read() times out rather than receiving a message
Property methods: HasMessageDisplayToLogical(), HasMessageGet(), HasMessageIsValid(), HasMessageLogicalToDisplay(), HasMessageNormalize(), HasMessageSet()
property Masked as %Boolean [ InitialExpression = 0 , Required ];
Set to 1 if the payload was received masked Always set to 1 in send
Property methods: MaskedDisplayToLogical(), MaskedGet(), MaskedIsValid(), MaskedLogicalToDisplay(), MaskedNormalize(), MaskedSet()
property MaskingKey as %Binary;
4-byte masking key (if Masked is true) If not provided prior to send, will be generated randomly

property RSV3 as %Boolean [ InitialExpression = 0 , Required ];
Reserved - always 0
Property methods: RSV3DisplayToLogical(), RSV3Get(), RSV3IsValid(), RSV3LogicalToDisplay(), RSV3Normalize(), RSV3Set()

Methods

method Mask(pString As %String) as %String [ Language = objectscript ]
Masks the input string by XOR-ing 4-byte chunks with the masking key
method Read(pTimeout As %Integer) [ Language = objectscript ]
Translates bytes read from the TCP device into a frame
method Write() [ Language = objectscript ]
Translates the frame into the wire format and writes it to the TCP device
