Add sequence. The sequence should have a unique name that shouldn't be altered after the sequence has been added - don't do: getSequence(name).setName(newName)) Don't use if the session is connected.

Add sequence. The sequence should have a unique name that shouldn't be altered after the sequence has been added - don't do: getSequence(name).setName(newName)) Use this method with isConnected parameter set to true to add a sequence to connected session. If sequencing is connected then the sequence is added only if there is no sequence with the same name already in use.

Add the parameter. Convert the parameter to a string and write it.

INTERNAL: Get platform specific connection properties.

Returns:Map<Object, Object>

properties to be added to connection properties

Redeclares org.eclipse.persistence.internal.core.databaseaccess.CorePlatform.convertObject.

Convert the object to the appropriate type by invoking the appropriate ConversionManager method

Parameters

sourceObject:Object

the object that must be converted

javaClass:Class<T>

the class that the object must be converted to

Returns:T

the newly converted object

Exceptions

ConversionException:

all exceptions will be thrown as this type.

Copy the state into the new platform.

Redeclares org.eclipse.persistence.internal.core.databaseaccess.CorePlatform.getConversionManager.

The platform hold its own instance of conversion manager to allow customization.

Annotations

@Override

Allow for the platform to handle the representation of parameters specially.

Get default sequence. Sequence name shouldn't be altered - don't do: getDefaultSequence().setName(newName).

INTERNAL: Used only for writing into XML or Java.

Return the driver version.

Delimiter to use for fields and tables using spaces or other special values. Some databases use different delimiters for the beginning and end of the value. This delimiter indicates the end of the value.

Get sequence corresponding to the name. The name shouldn't be altered - don't do: getSequence(name).setName(newName)

INTERNAL: Returns a map of sequence names to Sequences (may be null).

INTERNAL: Used only for writing into XML or Java.

Delimiter to use for fields and tables using spaces or other special values. Some databases use different delimiters for the beginning and end of the value. This delimiter indicates the start of the value.

Return the qualifier for the table. Required by some databases such as Oracle and DB2

Answer the timestamp from the server.

This method can be overridden by subclasses to return a query that will return the timestamp from the server. return null if the time should be the local time.

This method can be overridden by subclasses to return a query that will return the UUID from the server. return null if UUID generation is not available at the server.

Allow the platform to initialize itself after login/init.

INTERNAL: Initialize platform specific identity sequences. This method is called from EntityManagerSetupImpl after login and optional schema generation. Method is also called from TableCreator class during tables creation and update..

Parameters

session:Session

Active database session (in connected state).

defaultIdentityGenerator:String

Default identity generator sequence name.

Since

2.7

Remove all sequences that were added through addSequence method.

INTERNAL: Remove platform specific identity sequences for specified tables. Default identity sequences are restored. Method is also called from TableCreator class during tables removal.

Parameters

session:Session

Active database session (in connected state).

defaultIdentityGenerator:String

Default identity generator sequence name.

tableNames:Set<String>

Set of table names to check for identity sequence removal.

Since

2.7

Remove sequence corresponding to the name (the sequence was added through addSequence method) Don't use if the session is connected.

The platform hold its own instance of conversion manager to allow customization.

Set default sequence. The sequence should have a unique name that shouldn't be altered after the sequence has been set: don't do: getDefaultSequence().setName(newName)). Default constructors for Sequence subclasses set name to "SEQ".

INTERNAL: Used only for reading from XML.

Set the qualifier for the table. Required by some databases such as Oracle and DB2

Can override the default query for returning a timestamp from the server. See: getTimestampFromServer

Can override the default query for returning a UUID from the server.

Allow for the platform to handle the representation of parameters specially.

INTERNAL: Indicates whether defaultSequence is the same as platform default sequence.
