ZipFileCodeBaseEntry

public ZipFileCodeBaseEntry(ZipFileCodeBase codeBase,
                            java.util.zip.ZipEntry zipEntry)

Method Detail

getNumBytes

public int getNumBytes()

Description copied from interface: ICodeBaseEntry

Get the number of bytes in the resource. Returns <0 if the number of bytes is not known.

Returns:

number of bytes in the resource, or <0 if not known.

openResource

public java.io.InputStream openResource()
                                 throws java.io.IOException

Description copied from interface: ICodeBaseEntry

Open an input stream reading from the resource.

Returns:

InputStream reading from the resource.

Throws:

java.io.IOException - if an error occurs reading from the resource

public AbstractScannableCodeBase getCodeBase()

Description copied from interface: ICodeBaseEntry

Get the codebase this codebase entry belongs to.

Specified by:

getCodeBase in interface ICodeBaseEntry

Specified by:

getCodeBase in class AbstractScannableCodeBaseEntry

Returns:

the codebase this codebase entry belongs to

getRealResourceName

public java.lang.String getRealResourceName()

Specified by:

getRealResourceName in class AbstractScannableCodeBaseEntry

getClassDescriptor

public ClassDescriptor getClassDescriptor()

Description copied from interface: ICodeBaseEntry
