Method Detail

createDescriptor

public static BinaryTypeDescriptor createDescriptor(IClassFile classFile)

createDescriptor

public static BinaryTypeDescriptor createDescriptor(IType type)

create

public static IBinaryType create(IClassFile classFile,
                                 IProgressMonitor monitor)
                          throws JavaModelException,
                                 ClassFormatException

Throws:

JavaModelException

ClassFormatException

readType

public static IBinaryType readType(BinaryTypeDescriptor descriptor,
                                   IProgressMonitor monitor)
                            throws JavaModelException,
                                   ClassFormatException

Reads the given binary type. If the type can be found in the index with a fingerprint that exactly matches the file on disk, the type is read from the index. Otherwise the type is read from disk. Returns null if no such type exists.

Throws:

ClassFormatException

JavaModelException

rawReadType

public static ClassFileReader rawReadType(BinaryTypeDescriptor descriptor,
                                          boolean fullyInitialize)
                                   throws JavaModelException,
                                          ClassFormatException

Throws:

JavaModelException

ClassFormatException

rawReadTypeTestForExists

public static ClassFileReader rawReadTypeTestForExists(BinaryTypeDescriptor descriptor,
                                                       boolean fullyInitialize,
                                                       boolean useInvalidArchiveCache)
                                                throws JavaModelException,
                                                       ClassFormatException,
                                                       java.io.FileNotFoundException

Read the class file from disk, circumventing the index's cache. This should only be used by callers that need to read information from the class file which aren't present in the index (such as method bodies).

Returns:

the newly-created ClassFileReader or null if the given class file does not exist.

Throws:

ClassFormatException - if the class file existed but was corrupt

JavaModelException - if unable to read the class file due to a transient failure

java.io.FileNotFoundException - if the file does not exist

readFromIndex

public static IBinaryType readFromIndex(JavaIndex index,
                                        BinaryTypeDescriptor descriptor,
                                        IProgressMonitor monitor)
                                 throws JavaModelException,
                                        BinaryTypeFactory.NotInIndexException

Tries to read the given IBinaryType from the index. The return value is lightweight and may be cached with minimal memory cost. Returns an IBinaryType if the type was found in the index and the index was up-to-date. Throws a NotInIndexException if the index does not contain an up-to-date cache of the requested file. Returns null if the index contains an up-to-date cache of the requested file and it was able to determine that the requested class does not exist in that file.

Throws:

JavaModelException

BinaryTypeFactory.NotInIndexException
