Method Detail

getSlice

public Slice getSlice()
               throws java.io.IOException

Get the path to this zip entry, using "!/" as a separator between the parent logical zipfile and the entry name.

Returns:

the path of the entry

getLastModifiedTimeMillis

public long getLastModifiedTimeMillis()

Get the last modified time in Epoch millis, or 0L if unknown.

Returns:

the last modified time in Epoch millis.

compareTo

public int compareTo(FastZipEntry o)

Sort in decreasing order of version number, then lexicographically increasing order of unversioned entry path.

Specified by:

compareTo in interface java.lang.Comparable<FastZipEntry>

Parameters:

o - the object to compare to

Returns:

the result of comparison

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

toString

public java.lang.String toString()

Overrides:
