Example 9 with CategorizedProblem

use of org.eclipse.jdt.core.compiler.CategorizedProblem in project che by eclipse.

the class CheASTParser method internalCreateASTForKind.

/**
	 * Parses the given source between the bounds specified by the given offset (inclusive)
	 * and the given length and creates and returns a corresponding abstract syntax tree.
	 * <p>
	 * When the parse is successful the result returned includes the ASTs for the
	 * requested source:
	 * <ul>
	 * <li>{@link #K_CLASS_BODY_DECLARATIONS K_CLASS_BODY_DECLARATIONS}: The result node
	 * is a {@link TypeDeclaration TypeDeclaration} whose
	 * {@link TypeDeclaration#bodyDeclarations() bodyDeclarations}
	 * are the new trees. Other aspects of the type declaration are unspecified.</li>
	 * <li>{@link #K_STATEMENTS K_STATEMENTS}: The result node is a
	 * {@link Block Block} whose {@link Block#statements() statements}
	 * are the new trees. Other aspects of the block are unspecified.</li>
	 * <li>{@link #K_EXPRESSION K_EXPRESSION}: The result node is a subclass of
	 * {@link Expression Expression}. Other aspects of the expression are unspecified.</li>
	 * </ul>
	 * The resulting AST node is rooted under an contrived
	 * {@link CompilationUnit CompilationUnit} node, to allow the
	 * client to retrieve the following pieces of information
	 * available there:
	 * <ul>
	 * <li>{@linkplain CompilationUnit#getLineNumber(int) Line number map}. Line
	 * numbers start at 1 and only cover the subrange scanned
	 * (<code>source[offset]</code> through <code>source[offset+length-1]</code>).</li>
	 * <li>{@linkplain CompilationUnit#getMessages() Compiler messages}
	 * and {@linkplain CompilationUnit#getProblems() detailed problem reports}.
	 * Character positions are relative to the start of
	 * <code>source</code>; line positions are for the subrange scanned.</li>
	 * <li>{@linkplain CompilationUnit#getCommentList() Comment list}
	 * for the subrange scanned.</li>
	 * </ul>
	 * The contrived nodes do not have source positions. Other aspects of the
	 * {@link CompilationUnit CompilationUnit} node are unspecified, including
	 * the exact arrangment of intervening nodes.
	 * </p>
	 * <p>
	 * Lexical or syntax errors detected while parsing can result in
	 * a result node being marked as {@link ASTNode#MALFORMED MALFORMED}.
	 * In more severe failure cases where the parser is unable to
	 * recognize the input, this method returns
	 * a {@link CompilationUnit CompilationUnit} node with at least the
	 * compiler messages.
	 * </p>
	 * <p>Each node in the subtree (other than the contrived nodes)
	 * carries source range(s) information relating back
	 * to positions in the given source (the given source itself
	 * is not remembered with the AST).
	 * The source range usually begins at the first character of the first token
	 * corresponding to the node; leading whitespace and comments are <b>not</b>
	 * included. The source range usually extends through the last character of
	 * the last token corresponding to the node; trailing whitespace and
	 * comments are <b>not</b> included. There are a handful of exceptions
	 * (including the various body declarations); the
	 * specification for these node type spells out the details.
	 * Source ranges nest properly: the source range for a child is always
	 * within the source range of its parent, and the source ranges of sibling
	 * nodes never overlap.
	 * </p>
	 * <p>
	 * This method does not compute binding information; all <code>resolveBinding</code>
	 * methods applied to nodes of the resulting AST return <code>null</code>.
	 * </p>
	 *
	 * @return an AST node whose type depends on the kind of parse
	 *  requested, with a fallback to a <code>CompilationUnit</code>
	 *  in the case of severe parsing errors
	 * @see ASTNode#getStartPosition()
	 * @see ASTNode#getLength()
