- ## Method Details

  - ### addTerminalListener

    void addTerminalListener(ghidra.app.plugin.core.terminal.TerminalListener listener)
    Add a listener for terminal events
    Parameters:
      `listener` - the listener

  - ### removeTerminalListener

    void removeTerminalListener(ghidra.app.plugin.core.terminal.TerminalListener listener)
    Remove a listener for terminal events
    Parameters:
      `listener` - the listener

  - ### injectDisplayOutput

    void injectDisplayOutput(ByteBuffer bb)
    Process the given buffer as if it were output by the terminal's application.

    Warning: While implementations may synchronize to ensure the additional buffer is not processed at the same time as actual application input, there may not be any effort to ensure that the buffer is not injected in the middle of an escape sequence. Even if the injection is outside an escape sequence, this may still lead to unexpected behavior, since the injected output may be affected by or otherwise interfere with the application's control of the terminal's state. Generally, this should only be used for testing, or other cases when the caller knows it has exclusive control of the terminal.

    Parameters:
      `bb` - the buffer of bytes to inject

  - ### injectDisplayOutput

    default void injectDisplayOutput(byte[] arr)
    See Also:
      - `injectDisplayOutput(ByteBuffer)`

  - ### setSubTitle

    void setSubTitle(String title)
    Set the pane's sub title

    The application may also set this sub title using an escape sequence.

    Parameters:
      `title` - the new sub title

  - ### getSubTitle

    String getSubTitle()
    Get the pane's current sub title
    Returns:
      the sub title

  - ### setFixedSize

    void setFixedSize(short cols, short rows)
    Set the terminal size to the given dimensions, and do not resize it to the window.
    Parameters:
      `cols` - the number of columns
      `rows` - the number of rows

  - ### setFixedSize

    default void setFixedSize(int cols, int rows)
    See Also:
      - `setFixedSize(short, short)`

  - ### setDynamicSize

    void setDynamicSize()
    Fit the terminal's dimensions to the containing window.

  - ### setMaxScrollBackRows

    void setMaxScrollBackRows(int rows)
    Set the maximum size of the scroll-back buffer in lines

    This only affects the primary buffer. The alternate buffer has no scroll-back.

  - ### getColumns

    int getColumns()
    Get the maximum number of characters in each row
    Returns:
      the column count

  - ### getRows

    int getRows()
    Get the maximum number of rows in the display (not counting scroll-back)
    Returns:
      the row count

  - ### getScrollBackRows

    int getScrollBackRows()
    Get the number of lines in the scroll-back buffer
    Returns:
      the size of the buffer in lines

  - ### getFullText

    String getFullText()
    Get all the text in the terminal, including the scroll-back buffer
    Returns:
      the full text

  - ### getDisplayText

    String getDisplayText()
    Get the text in the terminal, excluding the scroll-back buffer
    Returns:
      the display text

  - ### getLineText

    String getLineText(int line)
    Get the given line's text

    The line at the top of the display has index 0. Lines in the scroll-back buffer have negative indices.

    Parameters:
      `line` - the index, 0 up
    Returns:
      the text in the line

  - ### getRangeText

    String getRangeText(int startCol, int startLine, int endCol, int endLine)
    Get the text in the given range

    The line at the top of the display has index 0. Lines in the scroll-back buffer have negative indices.

    Parameters:
      `startCol` - the first column to include in the starting line
      `startLine` - the first line to include
      `endCol` - the first column to exclude in the ending line
