JDOArrayImplDynamic

public JDOArrayImplDynamic()

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 JDOArray

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 JDOArray

Parameters:

embeddedElement - flag indicating whether the elements should be stored as part of the instance

getElementType

public JavaType getElementType()

Get the type representation of the array component type.

Specified by:

getElementType in interface JDOArray

Returns:

the array component type

isJDOArray

public boolean isJDOArray()

Determines whether this JDORelationship represents an array relationship or not. A return of true means this JDORelationship is a JDOArray instance.

Specified by:

isJDOArray in interface JDORelationship

Overrides:

isJDOArray in class JDORelationshipImpl

Returns:

true if this JDORelationship represents an array 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
