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 method getCapturedJavaBytes Returns 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 method getKeyboardLocked Returns the current state of the keyboard.
Public method getMaxDataCaptureLength Returns 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 method getObjectVersion Returns the version number of the specified Screen object.
Public method getOIAContents Returns the data displayed in the OIA portion (status line) of the presentation space.
Public method getOIAText Returns the text of the OIA portion (status line) of the presentation space in a string format.
Public method getOperatorDisable Gets the current Operator Disabled status for MATIP sessions.
Public method getPeripheralControl Gets the current peripheral control state for UTS INT-1 sessions.
Public method getRows Returns the number of rows in the presentation space.
Public method getScreenType Returns the current host type.
Public method getString Returns the visible text from the specified location.
Public method getStringEx Returns the visible text from the specified location with attributes matching those specified by inAttr.
Public method getText Returns the text contents of the presentation space as a string.
Public method GetType Gets the Type of the current instance. (inherited from Object)
Public method isConnected Returns the state of the host/gateway connection.
Public method isKeyboardLocked Returns the current state of the keyboard.
Public method Open Opens a host session.
Public method OpenEx Opens a host session, waiting a specified time for the connection to be established before returning.
Public method putString Copies a string of text to the specified position in the presentation space and returns the number of characters written.
Public method putStringEx Copies a string of text to the specified position in the presentation space and returns the number of characters written.
Public method RawDataTransmit Writes 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 method RawDataTransmitBytes Overloaded. 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.

Public method removeIScreenListenerEx Removes the ScreenListener from the Screen object. The Screen object will no longer receive screen/status event notifications.
Public method removeIStatusListener Removes the StatusListener from the Screen object. The Screen object will no longer receive status event notifications.
Public method sendKeys Sends 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 method SendStatus Overloaded. Sends a status message with option detail to screen.
Public method setCursor Sets the cursor position in the presentation space.
Public method setCursorColumn Sets the column of the cursor position.
Public method setCursorRow Sets the row of the cursor position.
Public method setDataCapture Turns the data capture facility on or off.
Public method setDataCaptureEx Turns the data capture facility on or off. In addition, turns on or off the suppression of updates to the presentation space.
Public method setDescription Creates a custom description for the instance of the Screen object.
Public method setgetText_Display Turns the getText_Display property on or off.
Public method setMaxDataCaptureLength Sets 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 method setOperatorDisable Attempts to set Operator Disabled status for MATIP sessions.
Public method setPeripheralControl Sets the Peripheral Control State for UTS INT-1 sessions. This advanced feature is for applications that want control over print activity.
Public method ToString Returns a String that represents the current Object. (inherited from Object)
Public method waitForCursor Waits for the cursor to appear at the specified position for a specified period of time.
Public method waitForString Waits for the specified text to appear at the specified position for a specified period of time.
Public method waitHostQuiet Waits 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).
