Method Detail

buildInteractionSpec

public javax.resource.cci.InteractionSpec buildInteractionSpec(org.eclipse.persistence.eis.interactions.EISInteraction interaction)

Allow the platform to build the interaction spec based on properties defined in the interaction.

Overrides:

buildInteractionSpec in class org.eclipse.persistence.eis.EISPlatform

buildRow

public org.eclipse.persistence.internal.sessions.AbstractRecord buildRow(javax.resource.cci.Record record,
                                                                         org.eclipse.persistence.eis.interactions.EISInteraction interaction,
                                                                         org.eclipse.persistence.eis.EISAccessor accessor)

INTERNAL: Allow the platform to handle record to row conversion.

Overrides:

buildRow in class org.eclipse.persistence.eis.EISPlatform

buildRows

public java.util.Vector buildRows(javax.resource.cci.Record record,
                                  org.eclipse.persistence.eis.interactions.EISInteraction interaction,
                                  org.eclipse.persistence.eis.EISAccessor accessor)

Allow the platform to handle record to row conversion.

Overrides:

buildRows in class org.eclipse.persistence.eis.EISPlatform

convertRecordBytesToString

protected void convertRecordBytesToString(org.eclipse.persistence.internal.nosql.adapters.nosql.OracleNoSQLRecord record)

INTERNAL: Convert the record and nested records bytes to strings.

createInputRecord

public javax.resource.cci.Record createInputRecord(org.eclipse.persistence.eis.interactions.EISInteraction interaction,
                                                   org.eclipse.persistence.eis.EISAccessor accessor)

Allow the platform to create the appropriate type of record for the interaction. Convert the nested local mapped record to a flat global keyed record.

Overrides:

createInputRecord in class org.eclipse.persistence.eis.EISPlatform

setDOMInRecord

public void setDOMInRecord(org.w3c.dom.Element dom,
                           javax.resource.cci.Record record,
                           org.eclipse.persistence.eis.interactions.EISInteraction interaction,
                           org.eclipse.persistence.eis.EISAccessor accessor)

Stores the XML DOM value into the record. XML is stored in Oracle NoSQL but storing the XML text, keyed on the object's "<dataTypeName>/<id>".

Overrides:

setDOMInRecord in class org.eclipse.persistence.eis.EISPlatform

createMajorKey

protected java.lang.Object createMajorKey(org.eclipse.persistence.descriptors.ClassDescriptor descriptor,
                                          org.eclipse.persistence.internal.sessions.AbstractRecord record,
                                          org.eclipse.persistence.eis.interactions.EISInteraction interaction,
                                          org.eclipse.persistence.eis.EISAccessor accessor)

NoSQL stores the data in a single big map. The keys are called major keys (minor keys are used to store the attributes). Major keys can have multiple values (and normally do). The first value is normally the type, then the id.

createDatabaseRowFromDOMRecord

public org.eclipse.persistence.internal.sessions.AbstractRecord createDatabaseRowFromDOMRecord(javax.resource.cci.Record record,
                                                                                               org.eclipse.persistence.eis.interactions.EISInteraction call,
                                                                                               org.eclipse.persistence.eis.EISAccessor accessor)

Allow the platform to handle the creation of the Record for the DOM record. Creates a DOM record from the XML data stored as a value in the OracleNoSQLRecord.

Overrides:

createDatabaseRowFromDOMRecord in class org.eclipse.persistence.eis.EISPlatform

initializeDefaultQueries

public void initializeDefaultQueries(org.eclipse.persistence.descriptors.DescriptorQueryManager queryManager,
                                     org.eclipse.persistence.internal.sessions.AbstractSession session)

INTERNAL: Allow the platform to initialize the CRUD queries to defaults. Configure the CRUD operations using GET/PUT and DELETE.

Overrides:

initializeDefaultQueries in class org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform

shouldPrepare

public boolean shouldPrepare(org.eclipse.persistence.queries.DatabaseQuery query)

Do not prepare to avoid errors being triggered for id and all queries.

Overrides:

shouldPrepare in class org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform

createPlatformDefaultSequence

protected org.eclipse.persistence.sequencing.Sequence createPlatformDefaultSequence()

INTERNAL: NoSQL does not support id generation, so use UUID as the default.

Overrides:

createPlatformDefaultSequence in class org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform
