Method Detail

createCodeFormatter

public static ICodeFormatter createCodeFormatter()

Deprecated. Use createCodeFormatter(Map) instead. Extension point is discontinued

Create an instance of a code formatter. A code formatter implementation can be contributed via the extension point "org.eclipse.jdt.core.codeFormatter". If unable to find a registered extension, the factory will default to using the default code formatter.

Returns:

an instance of a code formatter

See Also:

ICodeFormatter, createDefaultCodeFormatter(Map)

createCodeFormatter

public static CodeFormatter createCodeFormatter(java.util.Map options)

Create an instance of the built-in code formatter.

The given options should at least provide the source level (JavaCore.COMPILER_SOURCE), the compiler compliance level (JavaCore.COMPILER_COMPLIANCE) and the target platform (JavaCore.COMPILER_CODEGEN_TARGET_PLATFORM). Without these options, it is not possible for the code formatter to know what kind of source it needs to format.

Note this is equivalent to createCodeFormatter(options, M_FORMAT_NEW). Thus some code formatter options may be ignored. See @{link M_FORMAT_NEW for more details.

Parameters:

options - - the options map to use for formatting with the default code formatter. Recognized options are documented on JavaCore#getDefaultOptions(). If set to null, then use the current settings from JavaCore#getOptions.

Returns:

an instance of the built-in code formatter

Since:

3.0

createCodeFormatter

public static CodeFormatter createCodeFormatter(java.util.Map options,
                                                int mode)

Create an instance of the built-in code formatter.

The given options should at least provide the source level (JavaCore.COMPILER_SOURCE), the compiler compliance level (JavaCore.COMPILER_COMPLIANCE) and the target platform (JavaCore.COMPILER_CODEGEN_TARGET_PLATFORM). Without these options, it is not possible for the code formatter to know what kind of source it needs to format.

The given mode determines what options should be enabled when formatting the code. It can have the following values: M_FORMAT_NEW, M_FORMAT_EXISTING, but other values may be added in the future.

Parameters:

options - the options map to use for formatting with the default code formatter. Recognized options are documented on JavaCore#getDefaultOptions(). If set to null, then use the current settings from JavaCore#getOptions.

createScanner

public static IScanner createScanner(boolean tokenizeComments,
                                     boolean tokenizeWhiteSpace,
                                     boolean assertMode,
                                     boolean recordLineSeparator)

Create a scanner, indicating the level of detail requested for tokenizing. The scanner can then be used to tokenize some source in a Java aware way. Here is a typical scanning loop:

   IScanner scanner = ToolFactory.createScanner(false, false, false, false);
   scanner.setSource("int i = 0;".toCharArray());
   while (true) {
     int token = scanner.getNextToken();
     if (token == ITerminalSymbols.TokenNameEOF) break;
     System.out.println(token + " : " + new String(scanner.getCurrentTokenSource()));
   }
 

The returned scanner will tolerate unterminated line comments (missing line separator). It can be made stricter by using API with extra boolean parameter (strictCommentMode).

Parameters:

tokenizeComments - if set to false, comments will be silently consumed

tokenizeWhiteSpace - if set to false, white spaces will be silently consumed,

assertMode - if set to false, occurrences of 'assert' will be reported as identifiers (ITerminalSymbols#TokenNameIdentifier), whereas if set to true, it would report assert keywords (ITerminalSymbols#TokenNameassert). Java 1.4 has introduced a new 'assert' keyword.

recordLineSeparator - if set to true, the scanner will record positions of encountered line separator ends. In case of multi-character line separators, the last character position is considered. These positions can then be extracted using IScanner#getLineEnds. Only non-unicode escape sequences are considered as valid line separators.

Returns:

a scanner

                                     java.lang.String sourceLevel)

Create a scanner, indicating the level of detail requested for tokenizing. The scanner can then be used to tokenize some source in a Java aware way. Here is a typical scanning loop:

   IScanner scanner = ToolFactory.createScanner(false, false, false, false);
   scanner.setSource("int i = 0;".toCharArray());
   while (true) {
     int token = scanner.getNextToken();
     if (token == ITerminalSymbols.TokenNameEOF) break;
     System.out.println(token + " : " + new String(scanner.getCurrentTokenSource()));
