MongoTimestampElement

public MongoTimestampElement(String name,
                     long value)

Constructs a new MongoTimestampElement.

Parameters:

name - The name for the BSON long.

value - The BSON timestamp value as 4 byte increment and 4 byte timestamp.

Method Detail

accept

public void accept(Visitor visitor)

Accepts the visitor and calls the Visitor.visitMongoTimestamp(java.lang.String, long) method.

Parameters:

visitor - The visitor for the element.

See Also:

Element.accept(Visitor)

equals

public boolean equals(Object object)

Determines if the passed object is of this same type as this object and if so that its fields are equal.

Overrides:

equals in class AbstractElement

Parameters:

object - The object to compare to.

See Also:

Object.equals(java.lang.Object)

getTime

public long getTime()

Returns the BSON Mongo timestamp value as 4 byte increment and 4 byte timestamp.

Returns:

The BSON Mongo timestamp value as 4 byte increment and 4 byte timestamp.

getType

public ElementType getType()

Returns the type for the BSON type.

Returns:

The type for the BSON type.

hashCode

public int hashCode()

Computes a reasonable hash code.

Overrides:

hashCode in class AbstractElement

Returns:

The hash code value.

toString

public String toString()

String form of the object.

Overrides:

toString in class AbstractElement

Returns:

A human readable form of the object.

See Also:

Object.toString()

withName

public MongoTimestampElement withName(String name)

Creates a new element with the same type and value as this element but with the specified name. This is useful when creating a query across a set of collections where the filed name changes in the collections but the values must be identical.

Returns a new MongoTimestampElement.

Parameters:

name - The new name for the element.

Returns:

The created element.
