Field Detail

parentZipFileSlice

private final ZipFileSlice parentZipFileSlice

The parent slice, or null if this is the toplevel slice (the whole zipfile).

physicalZipFile

protected final PhysicalZipFile physicalZipFile

The underlying physical zipfile.

pathWithinParentZipFileSlice

private final java.lang.String pathWithinParentZipFileSlice

Constructor Detail

ZipFileSlice

ZipFileSlice(PhysicalZipFile physicalZipFile)

Create a ZipFileSlice that wraps a toplevel PhysicalZipFile.

Parameters:

physicalZipFile - the physical zipfile

ZipFileSlice

ZipFileSlice(PhysicalZipFile physicalZipFile,
             FastZipEntry zipEntry)

Create a ZipFileSlice that wraps a PhysicalZipFile that was extracted or inflated from a nested jar to memory or disk.

Parameters:

physicalZipFile - a physical zipfile that has been extracted to RAM

zipEntry - the zip entry

ZipFileSlice

ZipFileSlice(FastZipEntry zipEntry)
      throws java.io.IOException,
             java.lang.InterruptedException

Create a ZipFileSlice that wraps a single stored (not deflated) FastZipEntry.

Parameters:

zipEntry - the zip entry

Throws:

java.io.IOException - If an I/O exception occurs.

java.lang.InterruptedException - If the thread was interrupted.

ZipFileSlice

ZipFileSlice(ZipFileSlice other)

Clone constructor.

Parameters:

other - the ZipFileSlice to clone.

Method Detail

isAcceptedAndNotRejected

public boolean isAcceptedAndNotRejected(AcceptReject.AcceptRejectLeafname jarAcceptReject)

Check whether this zipfile slice and all of its parent slices are accepted and not rejected in the jarfile accept/reject criteria.

Parameters:

jarAcceptReject - the jar accept/reject criteria

Returns:

true if this zipfile slice and all of its parent slices are accepted and not rejected in the jarfile accept/reject criteria.

getParentZipFileSlice

public ZipFileSlice getParentZipFileSlice()

Get the parent ZipFileslice, or return null if this is a toplevel slice (i.e. if this slice wraps an entire physical zipfile).

Returns:

the parent ZipFileslice, or null if this is a toplevel slice.

getPathWithinParentZipFileSlice

public java.lang.String getPathWithinParentZipFileSlice()

Get the name of the slice (either the entry name/path within the parent zipfile slice, or the path of the physical zipfile if this slice is a toplevel slice (i.e. if this slice wraps an entire physical zipfile).

Returns:

the name of the slice.

appendPath

private void appendPath(java.lang.StringBuilder buf)

Recursively append the path in top down ancestral order.

Parameters:

buf - the buf to append the path to

getPath

public java.lang.String getPath()

Get the path of this zipfile slice, e.g. "/path/to/jarfile.jar!/nestedjar1.jar".

Returns:

the path of this zipfile slice.

getPhysicalFile

public java.io.File getPhysicalFile()

Get the physical File that this ZipFileSlice is a slice of.

Returns:

the physical File that this ZipFileSlice is a slice of, or null if this file was downloaded from a URL directly to RAM.
