Class CoreASTProvider
java.lang.Object
org.eclipse.jdt.core.manipulation.CoreASTProvider
The
CoreASTProvider
provides access to the AST root
used by
the current active Java editor.
The CoreASTProvider
contains all methods/functionality that are
not dependent on the UI, from org.eclipse.jdt.internal.ui.javaeditor.ASTProvider
for the purpose of reuse by non-UI bundles.
This class is not intended to be subclassed or instantiated by clients.
- Since:
- 1.10
- Restriction:
- This class is not intended to be instantiated by clients.

getAST
public CompilationUnit getAST(ITypeRoot input, CoreASTProvider.WAIT_FLAG waitFlag, org.eclipse.core.runtime.IProgressMonitor progressMonitor) Returns a shared compilation unit AST for the given Java element.Clients are not allowed to modify the AST and must synchronize all access to its nodes.
