Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters

obj:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

Annotations

@Override

The operating system the archive has been created on.

Returns:int

the host OS code

Implements org.apache.commons.compress.archivers.ArchiveEntry.getLastModifiedDate.

The last modified date of the entry.

Note the interpretation of time is different depending on the HostOS that has created the archive. While an OS that is considered to be Unix stores time in a time zone independent manner, other platforms only use the local time. I.e. if an archive has been created at midnight UTC on a machine in time zone UTC this method will return midnight regardless of time zone if the archive has been created on a non-Unix system and a time taking the current time zone into account if the archive has been created on Unix.

Returns:Date

the last modified date

Annotations

@Override

File mode of this entry.

The format depends on the host os that created the entry.

Returns:int

the file mode

Implements org.apache.commons.compress.archivers.ArchiveEntry.getName.

Gets this entry's name.

This method returns the raw name as it is stored inside of the archive.

Returns:String

This entry's name.

Annotations

@Override

Implements org.apache.commons.compress.archivers.ArchiveEntry.getSize.

Gets this entry's file size.

Returns:long

This entry's file size.

Annotations

@Override

File mode of this entry as Unix stat value.

Will only be non-zero of the host os was UNIX.

Returns:int

the Unix mode

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns:int

a hash code value for this object.

Annotations

@Override

Implements org.apache.commons.compress.archivers.ArchiveEntry.isDirectory.

True if the entry refers to a directory.

Returns:boolean

True if the entry refers to a directory

Annotations

Is the operating system the archive has been created on one that is considered a UNIX OS by arj?

Returns:boolean

whether the operating system the archive has been created on is considered a UNIX OS by arj
