Field Detail

TYPE

public static final ElementType TYPE

Deprecated.

The BSON type for a Object Id.

Constructor Detail

DBPointerElement

public DBPointerElement(String name,
                String dbName,
                String collectionName,
                ObjectId id)

Deprecated.

Constructs a new DBPointerElement.

Parameters:

name - The name for the BSON Object Id.

dbName - The database name.

collectionName - The name of the collection.

id - The object id.

Throws:

IllegalArgumentException - If the name, dbName, collectionName, or id is null.

DBPointerElement

public DBPointerElement(String name,
                String dbName,
                String collectionName,
                ObjectId id,
                long size)

Deprecated.

Constructs a new DBPointerElement.

Parameters:

name - The name for the BSON Object Id.

dbName - The database name.

collectionName - The name of the collection.

id - The object id.

size - The size of the element when encoded in bytes. If not known then use the DBPointerElement(String, String, String, ObjectId) constructor instead.

Throws:

IllegalArgumentException - If the name, dbName, collectionName, or id is null.

Method Detail

accept

public void accept(Visitor visitor)

Deprecated.

Accepts the visitor and calls the Visitor.visitDBPointer(java.lang.String, java.lang.String, java.lang.String, com.allanbank.mongodb.bson.element.ObjectId) method.

Parameters:

visitor - The visitor for the element.

See Also:

Element.accept(Visitor)

compareTo

public int compareTo(Element otherElement)

Deprecated.

Overridden to compare the elements based on the tuple (name, type, value).

Overridden to compare the elements based on the tuple (name, type). Derived classes are responsible for the value portion of the full comparison.

Overridden to compare the (database, collection, id) if the base class comparison is equals.

Specified by:

compareTo in interface Element

Specified by:

compareTo in interface Comparable<Element>

Overrides:

compareTo in class AbstractElement

equals

public boolean equals(Object object)

Deprecated.

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)

getCollectionName

public String getCollectionName()

Deprecated.

Returns the collectionName value.

Returns:

The collectionName value.

getDatabaseName

public String getDatabaseName()

Deprecated.

Returns the databaseName value.

Returns:

The databaseName value.

getId

public ObjectId getId()

Deprecated.

Returns the id value.

Returns:

The id value.

getType

public ElementType getType()

Deprecated.

Returns the type for the BSON type.

Returns:

The type for the BSON type.

getValueAsObject

public DocumentReference getValueAsObject()

Deprecated.

Returns the value for BSON element as a Java Object type.

Automatic conversion from the Object-ified value to an element is provided via the DocumentBuilder.add(String, Object) method. Not all element types will be successfully converted to the same element duing a Element-->Object value-->Element conversion. This cases are noted in the appropriate sub-type's JavaDoc.

Sub-types will also overload this method with the appropriate type returned. e.g., The StringElement.getValueAsObject() method signature returns a String.

Returns a DocumentReference.

Note: This value will not be recreated is a Object-->Element conversion. A more generic sub-document following the DBRef convention is created instead.

Returns:

The value for BSON element as a Java Object type.

hashCode

public int hashCode()

Deprecated.

Computes a reasonable hash code.

Overrides:

hashCode in class AbstractElement

Returns:

The hash code value.

withName

public DBPointerElement withName(String name)

Deprecated.

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 DBPointerElement.

Parameters:

name - The new name for the element.

Returns:

The created element.
