Method Detail

setValueInRecord

public void setValueInRecord(java.lang.String key,
                             java.lang.Object value,
                             javax.resource.cci.MappedRecord record,
                             org.eclipse.persistence.eis.EISAccessor accessor)

Mongo does not support all Java types. Convert unsupported types to string.

Overrides:

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

isLikeRegex

public boolean isLikeRegex()

Return if regex should be used for like.

setIsLikeRegex

public void setIsLikeRegex(boolean isLikeRegex)

Set if regex should be used for like.

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

createOutputRecord

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

For updates a separate translation record is required. The output row is used for this.

Overrides:

createOutputRecord 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

buildCallFromStatement

public org.eclipse.persistence.internal.databaseaccess.DatasourceCall buildCallFromStatement(org.eclipse.persistence.internal.expressions.SQLStatement statement,
                                                                                             org.eclipse.persistence.queries.DatabaseQuery query,

Overrides:

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

appendExpressionToQueryRow

protected void appendExpressionToQueryRow(org.eclipse.persistence.expressions.Expression expression,
                                          org.eclipse.persistence.internal.sessions.AbstractRecord row,
