Field Detail

embeddedElement

protected java.lang.Boolean embeddedElement
Property embeddedElement.


elementType

protected transient JavaType elementType
Property elementType.

Constructor Detail

JDOCollectionImplDynamic

public JDOCollectionImplDynamic()
Method Detail

isEmbeddedElement

public boolean isEmbeddedElement()
Determines whether the values of the elements should be stored if possible as part of the instance instead of as their own instances in the datastore.

Specified by:
isEmbeddedElement in interface JDOCollection
Returns:
true if the elements should be stored as part of the instance; false otherwise

setEmbeddedElement

public void setEmbeddedElement(boolean embeddedElement)
Set whether the values of the elements should be stored if possible as part of the instance instead of as their own instances in the datastore.

Specified by:
setEmbeddedElement in interface JDOCollection
Parameters:
embeddedElement - true if elements should be stored as part of the instance

getElementType

public JavaType getElementType()
Get the type representation of the collection elements.

Specified by:
getElementType in interface JDOCollection
Returns:
the element type

setElementType

public void setElementType(JavaType elementType)
Set the type representation of the collection elements.

Specified by:
setElementType in interface JDOCollection
Parameters:
elementType - the type representation of the collection elements

getElementTypeName

public java.lang.String getElementTypeName()
Get the type of collection elements as string.

Specified by:
getElementTypeName in interface JDOCollection
Returns:
the element type as string

setElementTypeName

public void setElementTypeName(java.lang.String elementTypeName)
Set string representation of the type of collection elements.

Specified by:
setElementTypeName in interface JDOCollection
Parameters:
elementTypeName - a string representation of the type of elements in the collection.

isJDOCollection

public boolean isJDOCollection()
Determines whether this JDORelationship represents a collection relationship or not. A return of true means this JDORelationship is a JDOCollection instance.

Specified by:
isJDOCollection in interface JDORelationship
Overrides:
isJDOCollection in class JDORelationshipImpl
Returns:
true if this JDORelationship represents a collection relationship; false otherwise.

getRelatedJavaType

public JavaType getRelatedJavaType()
Get the type representation of the relationship. This will be the JavaType for references, the element type for collections and arrays, and the value type for maps.

Specified by:
getRelatedJavaType in class JDORelationshipImpl
Returns:
the relationship type
