Examples of org.eclipse.jdt.core.dom.ASTParser

org.eclipse.jdt.core.dom.ASTParser
les JDK 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6 parser.setSource(source); // In order to parse 1.5 code, some compiler options need to be set to 1.5 Map options = JavaCore.getOptions(); JavaCore.setComplianceOptions(JavaCore.VERSION_1_5, options); parser.setCompilerOptions(options); CompilationUnit result = (CompilationUnit) parser.createAST(null); Once a configured parser instance has been used to create an AST, the settings are automatically reset to their defaults, ready for the parser instance to be reused.

There are a number of configurable features:
- Source string from {@link #setSource(char[]) char[]}, {@link #setSource(ICompilationUnit) ICompilationUnit}, or {@link #setSource(IClassFile) IClassFile}, and limited to a specified {@linkplain #setSourceRange(int,int) subrange}.
- Whether {@linkplain #setResolveBindings(boolean) bindings} will be created.
- Which {@linkplain #setWorkingCopyOwner(WorkingCopyOwner) working copy owner} to use when resolving bindings.
- A hypothetical {@linkplain #setUnitName(String) compilation unit file name}and {@linkplain #setProject(IJavaProject) Java project}for locating a raw source string in the Java model (when resolving bindings)
- Which {@linkplain #setCompilerOptions(Map) compiler options}to use. This is especially important to use if the parsing/scanning of the source code requires a different version than the default of the workspace. For example, the workspace defaults are 1.4 and you want to create an AST for a source code that is using 1.5 constructs.
- Whether to parse just {@linkplain #setKind(int) an expression, statements,or body declarations} rather than an entire compilation unit.
- Whether to return a {@linkplain #setFocalPosition(int) abridged AST}focused on the declaration containing a given source position.
