Field Detail

unit

protected ICompilationUnit unit

The handle to the compilation unit being parsed

unitInfo

protected CompilationUnitElementInfo unitInfo

The info object for the compilation unit being parsed

importContainerInfo

protected org.aspectj.org.eclipse.jdt.internal.core.JavaElementInfo importContainerInfo

The import container info - null until created

newElements

protected java.util.Map newElements

Hashtable of children elements of the compilation unit. Children are added to the table as they are found by the parser. Keys are handles, values are corresponding info objects.

infoStack

protected java.util.Stack infoStack

Stack of parent scope info objects. The info on the top of the stack is the parent of the next element found. For example, when we locate a method, the parent info object will be the type the method is contained in.

children

protected java.util.HashMap children

handleStack

protected java.util.Stack handleStack

Stack of parent handles, corresponding to the info stack. We keep both, since info objects do not have back pointers to handles.

referenceCount

protected int referenceCount

The number of references reported thus far. Used to expand the arrays of reference kinds and names.

hasSyntaxErrors

protected boolean hasSyntaxErrors

Problem requestor which will get notified of discovered problems

parser

protected Parser parser

NO_BYTES

protected static byte[] NO_BYTES

Empty collections used for efficient initialization

fieldRefCache

protected HashtableOfObject fieldRefCache

messageRefCache

protected HashtableOfObject messageRefCache

typeRefCache

protected HashtableOfObject typeRefCache

unknownRefCache

protected HashtableOfObject unknownRefCache

CompilationUnitStructureRequestor

protected CompilationUnitStructureRequestor(ICompilationUnit unit,
                                            CompilationUnitElementInfo unitInfo,
                                            java.util.Map newElements)

Method Detail

acceptImport

public void acceptImport(int declarationStart,
                         int declarationEnd,
                         char[][] tokens,
                         boolean onDemand,
                         int modifiers)

Specified by:

acceptImport in interface ISourceElementRequestor

Parameters:

declarationStart - This is the position of the first character of the import keyword.

declarationEnd - This is the position of the ';' ending the import statement or the end of the comment following the import.

tokens - This are the tokens of the import like specified in the source.

onDemand - set to true if the import is an import on demand (e.g. import java.io.*). False otherwise.

modifiers - can be set to static from 1.5 on.
