Enum IdentifierResolutionStrategy

java.lang.Object

java.lang.Enum<IdentifierResolutionStrategy>

com.holonplatform.datastore.jdbc.config.IdentifierResolutionStrategy

All Implemented Interfaces:

Serializable, Comparable<IdentifierResolutionStrategy>

public enum IdentifierResolutionStrategy
extends Enum<IdentifierResolutionStrategy>

Enumeration of the available PropertyBox/PropertySet identifier resolution strategies.

The identifier resolution strategy is used by the JDBC Datastore to perform operations which involve a PropertyBox and for which the PropertyBox identifier properties are required to match the PropertyBox data with the database table primary key.

The JDBC Datastore operations which require a consistent idenfier resolution are: DatastoreOperations.refresh(com.holonplatform.core.datastore.DataTarget, PropertyBox), DatastoreOperations.save(com.holonplatform.core.datastore.DataTarget, PropertyBox, com.holonplatform.core.datastore.DatastoreOperations.WriteOption...), DatastoreOperations.update(com.holonplatform.core.datastore.DataTarget, PropertyBox, com.holonplatform.core.datastore.DatastoreOperations.WriteOption...), DatastoreOperations.delete(com.holonplatform.core.datastore.DataTarget, PropertyBox, com.holonplatform.core.datastore.DatastoreOperations.WriteOption...).

Since:

5.1.0

Enum Constant Detail

AUTO

public static final IdentifierResolutionStrategy AUTO

If the PropertySet bound to the PropertyBox provides provides a not empty identifier property set, use it as PropertyBox identifier. Otherwise, try to obtain the PropertyBox identifier properties from the database table primary key.

IDENTIFIER_PROPERTIES

public static final IdentifierResolutionStrategy IDENTIFIER_PROPERTIES

Use the PropertySet identifier properties as PropertyBox identifier.

See Also:

PropertySet.getIdentifiers()

TABLE_PRIMARY_KEY

public static final IdentifierResolutionStrategy TABLE_PRIMARY_KEY

Use the database table primary key to obtain the PropertyBox identifier.

Method Detail

values

public static IdentifierResolutionStrategy[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (IdentifierResolutionStrategy c : IdentifierResolutionStrategy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static IdentifierResolutionStrategy valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
