Field Details

shouldReadWholeDocument

protected boolean shouldReadWholeDocument

Indicates if we should initialize the whole DOM on a read. This is only used if the user is mapping from an Oracle Document implementation.

Constructor Details

DirectToXMLTypeMapping

public DirectToXMLTypeMapping()

Method Details

preInitialize

public void preInitialize(org.eclipse.persistence.internal.sessions.AbstractSession session)
                   throws DescriptorException

INTERNAL: Default to mutable if mapped as a DOM.

Overrides:

preInitialize in class AbstractDirectMapping

Throws:

DescriptorException

initialize

public void initialize(org.eclipse.persistence.internal.sessions.AbstractSession session)
                throws DescriptorException

INTERNAL: The mapping is initialized with the given session. This mapping is fully initialized after this.

Overrides:

initialize in class AbstractDirectMapping

Throws:

DescriptorException

setShouldReadWholeDocument

public void setShouldReadWholeDocument(boolean readWholeDocument)

PUBLIC:

Parameters:

readWholeDocument - - determines if the Oracle XDB DOM should be fully initialized on a read.

shouldReadWholeDocument

public boolean shouldReadWholeDocument()

PUBLIC:

Returns:

boolean - returns true if currently initializing DOMs on reads.

getObjectValue

public Object getObjectValue(Object fieldValue,
 Session session)
                      throws ConversionException

INTERNAL: Get the attribute value for the given field value. If we're mapping to a Document, we need to check if we should return the Oracle DOM or build a new one.

Overrides:

getObjectValue in class AbstractDirectMapping

Throws:

ConversionException

isDirectToXMLTypeMapping

public boolean isDirectToXMLTypeMapping()

Description copied from class: DatabaseMapping

INTERNAL: Related mapping should implement this method to return true.

Overrides:

isDirectToXMLTypeMapping in class DatabaseMapping

buildCloneValue

protected Object buildCloneValue(Object attributeValue,
 org.eclipse.persistence.internal.sessions.AbstractSession session)

INTERNAL: Clone the DOM Document if required.

Overrides:

buildCloneValue in class AbstractDirectMapping

compareObjectValues

protected boolean compareObjectValues(Object firstValue,
 Object secondValue,
 org.eclipse.persistence.internal.sessions.AbstractSession session)

INTERNAL: Compare the attribute values. Compare Nodes if mapped as a DOM.

Overrides:

compareObjectValues in class AbstractDirectMapping
