Class LogRenderer

java.lang.Object

ai.attackframework.tools.burp.ui.log.LogRenderer

public final class LogRenderer
extends Object

Renderer: writes/replaces lines in the document, formats output, and autoscrolls. Uses plain text (no per-level styling) so the log can use JTextArea with line wrap.

Threading: expected on the EDT.

State: bookkeeping for "the last rendered line" is read directly from the document's line element model rather than cached. This keeps replaceLast(java.lang.String, ai.attackframework.tools.burp.ui.log.LogStore.Level) correct even when other callers (for example removeLeadingLines(int)) have shifted the document underneath us during an incremental trim.

Constructor Details

LogRenderer

public LogRenderer(JTextComponent textComponent)

Creates a renderer bound to the provided text component (e.g. JTextArea for line wrap).

Caller must construct on the EDT.

Parameters:

textComponent - target component to render into (must have an AbstractDocument)

Method Details

clear

public void clear()

Clears all rendered content.

EDT only.

append

public void append(String line,
 LogStore.Level level)

Appends a formatted line to the document.

Parameters:

line - text to append (should include trailing newline)

level - log level (unused; kept for API compatibility)

replaceLast

public void replaceLast(String line,
 LogStore.Level level)

Replaces the document's final content line (the last newline-terminated line) with line. No-op when the document is empty.

Parameters:

line - replacement text (should include trailing newline)

level - log level (unused; kept for API compatibility)

removeLeadingLines

public void removeLeadingLines(int lineCount)

Removes the first lineCount content lines from the document in a single AbstractDocument.remove(int, int) call. Used by incremental trim so the renderer never has to clear and re-append the entire document just to drop a few head entries.

Parameters:

lineCount - number of leading newline-terminated lines to remove (clamped to the number of content lines actually present)

prependLines

public void prependLines(String text)

Inserts text at offset 0. Intended for the suffix-diff trim path where a new leading prefix replaces a removed one; callers concatenate multiple lines into a single string so a single AbstractDocument.insertString(int, java.lang.String, javax.swing.text.AttributeSet) call covers them all.

Parameters:

text - text to prepend (each logical line should already end in "\n")

autoscrollIfNeeded

public void autoscrollIfNeeded(boolean paused)

Scrolls to the bottom unless paused.

formatLine

public String formatLine(LocalDateTime ts,
 LogStore.Level lvl,
 String msg,
 int repeats)

Formats a log entry into a single rendered line.

Parameters:

ts - timestamp (fallbacks to now when null)

lvl - log level

msg - log message (nullable)

repeats - duplicate count; >1 renders as (xN)

Returns:

formatted line including trailing newline
