Method Details

• connect

  boolean connect()

  Connects the session to host.

• disconnect

  boolean disconnect()

  Disconnects the session from host.

• getScreenSize

  Size getScreenSize()

  Gets the current screen size.

• getScreenLength

  int getScreenLength()

  Gets the current screen length (width * height).

• sendCharacterString

  boolean sendCharacterString(String keys)

  Sends character keystrokes to host.

• sendKey

  boolean sendKey(int key)

  Sends keystrokes to host.

  • HostSendKeys

• setHostString

  boolean setHostString(int x, int y, int offset, int length, String string)

  Sets a string to a host field.

• setHostStringAsKeys

  boolean setHostStringAsKeys(int x, int y, int offset, int length, String string)

  Sets a string to a host field just as if the user typed the characters. The host field is first cleared with (3270) Clear EOF or (5250) Field Exit or Field Minus (for negative numbers in a numeric field). The string is then entered as a set of keystrokes, followed by a potential Field Exit or Field Minus (for negative numbers in a numeric field), but only for 5250.

• doesHostNeedFieldExit

  boolean doesHostNeedFieldExit(int x, int y, int offset, int length, String string)

  For 5250: checks if a field has the attributes that requires this particular string to enter the data followed by a "Field Exit" or "Field Minus" key.

  Returns:

  false=field doesn't require field exit, true=field requires field exit.

• setCursor

  boolean setCursor(int x, int y)

  Sets the host cursor position.

• getCursor

  Position getCursor()

  Gets the current host cursor position.

• getCharactersAndAttributes

  void getCharactersAndAttributes(char[] chars, int[] attrbs, int beginPos, int endPos)

  Gets the characters and attributes between two positions, including the end position.

• getCharactersAndAttributes

  void getCharactersAndAttributes(char[] chars, int[] attrbs, int beginPos, int endPos, char fieldOrNullChar)

  Gets the characters and attributes between two positions, including the end position. The character "fieldOrNullChar" is the character that will be used instead of field attributes and null characters.

• getSessionState

  int getSessionState()

  Gets the current session state.

  Returns:

  A combination of HostSessionPeer.STATE_* flags is returned.

• getComm

  SocketCommNIO getComm()

  Gets the communication engine.

  Returns:

  The NIO instance.

  Returns:

  false if 5250,

  Checks if this is a printer or not.

• getLastError

  String getLastError(boolean doClear)

  Returns:

  null if the session doesn't support it (3270 doesn't).

• setLastError

  void setLastError(String errMsg)

  Sets the last error message of the session.

• getDeviceName

  Gets the device name of the session.

  Returns:

  null if no device name exists.

• isProcessingDataStream

  Sets the insert mode.

  Returns:

  true for success, false for failure.

• doesFieldHaveExtendedAttributes

  boolean doesFieldHaveExtendedAttributes(HostField hostField)

  Checks if a host field has extended attributes or not. 5250 never has, but 3270 could have, e.g. special highlighting.

• getNewCharAttribute

  int getNewCharAttribute(HostField hostField)

  Gets the attribute to use for new characters in a field that contains extended attributes (always zero for non-3270).

• getClientHostFieldFlags

  int getClientHostFieldFlags(HostField hostField)

  Gets flags that are required for the client host fields for local editing, etc.

• isAutoReconnectSessionEnabled

  boolean isAutoReconnectSessionEnabled()

  Checks if the use of auto reconnect session is handled or not.

• getHomeAddress

  int getHomeAddress()

  Gets the host address index on the screen.

• setHostField

  boolean setHostField(HostField hostField, String data, int[] attrs)

  Sets a host field fully with text data and perhaps attributes (if these are non-null).

  Returns:

  true for success, false for failure.

• getAllowedCharacters

  String getAllowedCharacters()

  Gets the string of characters that can be input by the user using the configured host code page for this session.

  If the return string is empty, for the EE package for example, all characters are "inputable".
