Constructors Summary

public BaseDumper(byte[] bytes, PrintStream out, String filePath, Args args) Constructs an instance. param bytes {@code non-null;} bytes of the (alleged) class file on the left) param out {@code non-null;} where to dump to param filePath the file path for the class, excluding any base directory specification this.bytes = bytes; this.rawBytes = args.rawBytes; this.out = out; this.width = (args.width <= 0) ? 79 : args.width; this.filePath = filePath; this.strictParse = args.strictParse; this.indent = 0; this.separator = rawBytes ? "|" : ""; this.at = 0; this.args = args; int hexCols = (((width - 5) / 15) + 1) & ~1; if (hexCols < 6) { hexCols = 6; } else if (hexCols > 10) { hexCols = 10; } this.hexCols = hexCols;

Methods Summary
public void	changeIndent(int indentDelta) {@inheritDoc} indent += indentDelta; separator = rawBytes ? "|" : ""; for (int i = 0; i < indent; i++) { separator += " "; }
static int	computeParamWidth(com.android.dx.cf.code.ConcreteMethod meth, boolean isStatic) Computes the total width, in register-units, of the parameters for this method. param meth method to process return width in register-units return meth.getEffectiveDescriptor().getParameterTypes(). getWordCount();
public void	endParsingMember(com.android.dx.util.ByteArray bytes, int offset, java.lang.String name, java.lang.String descriptor, com.android.dx.cf.iface.Member member) {@inheritDoc} // This space intentionally left blank.
protected final int	getAt() Gets the current dump cursor (that is, the offset of the expected next byte to dump). return {@code >= 0;} the dump cursor return at;
protected final byte[]	getBytes() Gets the array of {@code byte}s to process. return {@code non-null;} the bytes return bytes;
protected final java.lang.String	getFilePath() Gets the filesystem/jar path of the file being dumped. return {@code non-null;} the path return filePath;
protected final boolean	getRawBytes() Gets whether this dump is to include raw bytes. return the raw bytes flag return rawBytes;
protected final boolean	getStrictParse() Gets whether to be strict about parsing. return whether to be strict about parsing return strictParse;
protected final int	getWidth1() Gets the width of the first column of output. This is {@code 0} unless raw bytes are being included in the output. return {@code >= 0;} the width of the first column if (rawBytes) { return 5 + (hexCols * 2) + (hexCols / 2); } return 0;
protected final int	getWidth2() Gets the width of the second column of output. return {@code >= 0;} the width of the second column int w1 = rawBytes ? (getWidth1() + 1) : 0; return width - w1 - (indent * 2);
protected final java.lang.String	hexDump(int offset, int len) Constructs a hex data dump of the given portion of {@link #bytes}. param offset offset to start dumping at param len length to dump return {@code non-null;} the dump return Hex.dump(bytes, offset, len, offset, hexCols, 4);
public void	parsed(com.android.dx.util.ByteArray bytes, int offset, int len, java.lang.String human) {@inheritDoc} offset = bytes.underlyingOffset(offset, getBytes()); boolean rawBytes = getRawBytes(); if (offset < at) { println("<dump skipped backwards to " + Hex.u4(offset) + ">"); at = offset; } else if (offset > at) { String hex = rawBytes ? hexDump(at, offset - at) : ""; print(twoColumns(hex, "<skipped to " + Hex.u4(offset) + ">")); at = offset; } String hex = rawBytes ? hexDump(offset, len) : ""; print(twoColumns(hex, human)); at += len;
protected final void	print(java.lang.String s) Prints the given string to this instance's output stream. param s {@code null-ok;} string to print out.print(s);
protected final void	println(java.lang.String s) Prints the given string to this instance's output stream, followed by a newline. param s {@code null-ok;} string to print out.println(s);
protected final void	setAt(com.android.dx.util.ByteArray arr, int offset) Sets the dump cursor to the indicated offset in the given array. param arr {@code non-null;} array in question param offset {@code >= 0;} offset into the array at = arr.underlyingOffset(offset, bytes);
public void	startParsingMember(com.android.dx.util.ByteArray bytes, int offset, java.lang.String name, java.lang.String descriptor) {@inheritDoc} // This space intentionally left blank.
protected final java.lang.String	twoColumns(java.lang.String s1, java.lang.String s2) Combines a pair of strings as two columns, or if this is one-column output, format the otherwise-second column. param s1 {@code non-null;} the first column's string param s2 {@code non-null;} the second column's string return {@code non-null;} the combined output int w1 = getWidth1(); int w2 = getWidth2(); try { if (w1 == 0) { int len2 = s2.length(); StringWriter sw = new StringWriter(len2 * 2); IndentingWriter iw = new IndentingWriter(sw, w2, separator); iw.write(s2); if ((len2 == 0) || (s2.charAt(len2 - 1) != '\n")) { iw.write('\n"); } iw.flush(); return sw.toString(); } else { return TwoColumnOutput.toString(s1, w1, separator, s2, w2); } } catch (IOException ex) { throw new RuntimeException(ex); }
