Method Details

getId

public String getId()

Returns:

the String representation of this ID.

parse

public static ObjectId parse(String id)

Create an ObjectId from an existing String representation if possible.

Parameters:

id - the String representation of the ObjectId.

Returns:

the ObjectId on success, null otherwise.

create

public static ObjectId create(byte[] data,
 int offset,
 int len)

Create an ObjectId by calculating the ID of the given content.

createByCopy

public static ObjectId createByCopy(InputStream source,
 Path target)
                             throws IOException

Create an ObjectId by calculating the ID of the content of the given source InputStream. While doing so, copy the content to the given target Path as well.

Throws:

IOException

createFromStreamNoCopy

public static ObjectId createFromStreamNoCopy(InputStream source)

Creates an ObjectId by calculating the ID of the content of the given InputStream.

This method is meant for validation purposes only. To create objects in the database use createByCopy(InputStream, Path) as this copies the data while hashing.

toString

public String toString()

Overrides:

toString in class Object

compareTo

public int compareTo(ObjectId o)

Specified by:

compareTo in interface Comparable<ObjectId>

hashCode

@Generated("Eclipse")
public int hashCode()

Overrides:

hashCode in class Object

equals

@Generated("Eclipse")
public boolean equals(Object obj)

Overrides:

equals in class Object
