 NameDescription
Public MethodaddIScreenListenerExEnables your application to receive various screen event notifications from the Screen object.

Public MethodfindFieldExSearches the presentation space for the specified field beginning from the index (field number) specified.  
Public MethodfindStringSearches the presentation space for the specified text string starting from the specified start position. If found, it returns true and the start position of the string.  
Public MethodfindStringExSearches the presentation space for the specified text string from the specified start position to the specified end position. If found, it returns true and the start position of the string.  
Public MethodgetCapturedBytesReturns the currently captured data as a byte array. The data capture facility allows you to save all information being sent by the host communications layer to the presentation space for later retrieval as a byte array or a String.

Depending on the type of terminal and type of host connection, this data may be in the 8-bit ASCII, 8-bit EBCDIC or 6-bit ALC character set.

 
Public MethodgetCapturedDataReturns the currently captured data as a string. The data capture facility allows you to save all information being sent by the host communications layer to the presentation space for later retrieval as a byte array or a String. Depending on the type of terminal and type of host connection, this data may be in the 8-bit ASCII, 8-bit EBCDIC or 6-bit ALC character set.  
Public MethodgetCapturedJavaBytesReturns the currently captured data as a signed byte array. The data capture facility allows you to save all information being sent by the host communications layer to the presentation space for later retrieval as a byte array or a String.

Depending on the type of terminal and type of host connection, this data may be in the 8-bit ASCII, 8-bit EBCDIC or 6-bit ALC character set.

 
Public MethodgetColumnsReturns the number of columns in the presentation space.  
Public MethodgetCursorReturns the current cursor position.  
Public MethodgetCursorColumnReturns the column of the current cursor position.  
Public MethodgetCursorRowReturns the row of the current cursor position.  
Public MethodgetDataCaptureReturns the current state of the data capture facility.  
Public MethodgetDescriptionReturns a custom description for the instance of the Screen object if a description was created previously using setDescription.  
Public MethodgetExtPSReturns the specified portion of the presentation space in a string format.  
Public MethodgetgetText_DisplayReturns the current setting of the getText_Display property.  
Public MethodGetHashCode (Inherited from object)
Public MethodgetKeyboardLockedReturns the current state of the keyboard.  
Public MethodgetMaxDataCaptureLengthReturns the current maximum buffer size for data captured using the data capture facility. The data capture facility allows you to save all information being sent to the presentation space by the host for later retrieval as a byte array or a string.  
Public MethodgetObjectVersionReturns the version number of the specified Screen object.  
Public MethodgetOIAContentsReturns the data displayed in the OIA portion (status line) of the presentation space.  
Public MethodgetOIATextReturns the text of the OIA portion (status line) of the presentation space in a string format.  
Public MethodgetOperatorDisableGets the current Operator Disabled status for MATIP sessions.  
Public MethodgetPeripheralControlGets the current peripheral control state for UTS INT-1 sessions.  
Public MethodgetRowsReturns the number of rows in the presentation space.  
Public MethodgetScreenTypeReturns the current host type.  
Public MethodgetStringReturns the visible text from the specified location.  
Public MethodgetStringExReturns the visible text from the specified location with attributes matching those specified by inAttr.  
Public MethodgetTextReturns the text contents of the presentation space as a string.  
Public MethodGetType (Inherited from object)
Public MethodisConnectedReturns the state of the host/gateway connection.  
Public MethodisKeyboardLockedReturns the current state of the keyboard.  
Public MethodOpenOpens a host session.  
Public MethodOpenExOpens a host session, waiting a specified time for the connection to be established before returning.  
Public MethodputStringCopies a string of text to the specified position in the presentation space and returns the number of characters written.  
Public MethodputStringExCopies a string of text to the specified position in the presentation space and returns the number of characters written.  
Public MethodRawDataTransmitWrites a string of characters directly to the host communications layer, without going through the presentation space. The Unicode characters are converted to bytes with the default encoding for the platform.

Depending on the type of terminal and type of host connection, this data may have to be in the 8-bit ASCII, 8-bit EBCDIC or 6-bit ALC character set.

 
Public MethodRawDataTransmitBytesOverloaded. Writes an array of bytes directly to the host communications layer, without going through the presentation space.

Depending on the type of terminal and type of host connection, this data may have to be in the 8-bit ASCII, 8-bit EBCDIC or 6-bit ALC character set.

In the case of ALC, you must have two leading placeholder characters and one trailing placeholder character in your buffer (i.e. nn mm "real data" zz).

 
Public MethodremoveIScreenListenerExRemoves the ScreenListener from the Screen object. The Screen object will no longer receive screen/status event notifications.  
Public MethodremoveIStatusListenerRemoves the StatusListener from the Screen object. The Screen object will no longer receive status event notifications.  
Public MethodsendKeysSends characters and special keys to the session. They are treated the same as if they were typed at the keyboard. Special keystrokes can be specified in HLLAPI format, which has a special code for each keystroke, such as "@E" for the host Transmit key, or Braces format, where the key name is surrounded by braces, such as "{Transmit}". See Key Codes for a complete list of codes for each host type. You can also use sendKeys to send text character strings to the session. Text is sent to the host or written to the presentation space at the current cursor location. For example, to send the text "logoff" followed by the Transmit key, inText would be "logoff@T". If you are sending a lot of text to the presentation space, however, it may be more efficient to use putString or putStringEx instead. If an invalid key sequence is detected, no characters or keys are sent. It is recommended that you follow every sendKey call with a call to one of the wait methods (for example, WaitForString , WaitHostQuiet, or WaitForCursor). This helps to ensure that the host has completed processing before your application moves on to the next step.  
Public MethodSendStatusOverloaded. Sends a status message with option detail to screen.  
Public MethodsetCursorSets the cursor position in the presentation space.  
Public MethodsetCursorColumnSets the column of the cursor position.  
Public MethodsetCursorRowSets the row of the cursor position.  
Public MethodsetDataCaptureTurns the data capture facility on or off.  
Public MethodsetDataCaptureExTurns the data capture facility on or off. In addition, turns on or off the suppression of updates to the presentation space.  
Public MethodsetDescriptionCreates a custom description for the instance of the Screen object.  
Public MethodsetgetText_DisplayTurns the getText_Display property on or off.  
Public MethodsetMaxDataCaptureLengthSets the maximum buffer size for data captured using the data capture facility. The data capture facility allows you to save all information being sent to the presentation space by the host for later retrieval as a byte array or a string.  
Public MethodsetOperatorDisableAttempts to set Operator Disabled status for MATIP sessions.  
Public MethodsetPeripheralControlSets the Peripheral Control State for UTS INT-1 sessions. This advanced feature is for applications that want control over print activity.  
Public MethodToString (Inherited from object)
Public MethodwaitForCursorWaits for the cursor to appear at the specified position for a specified period of time.  
Public MethodwaitForStringWaits for the specified text to appear at the specified position for a specified period of time.  
Public MethodwaitHostQuietWaits for the host session to be idle for a specified period of time (in milliseconds). A session is considered to be "quiet" when there has been no activity in the host session for the specified amount of time. This is a synchronous call and does not return until the wait condition is satisfied. Otherwise, it times out after wtTime (specified in milliseconds).
