Class StoredDatabaseInfo

java.lang.Object

com.amazon.carbonado.repo.sleepycat.StoredDatabaseInfo

All Implemented Interfaces:

Unevolvable, Unindexed, Storable

@PrimaryKey(value="databaseName")
@Independent
@Alias(value="CARBONADO_DATABASE_INFO")
public abstract class StoredDatabaseInfo
extends java.lang.Object
implements Storable, Unevolvable, Unindexed

Stores basic information about the BDB databases managed by BDBRepository.

Note: This storable cannot have indexes defined, since it is used to discover information about indexes. It would create a cyclic dependency.

Constructor Detail

StoredDatabaseInfo

public StoredDatabaseInfo()

Method Detail

getDatabaseName

public abstract java.lang.String getDatabaseName()

setDatabaseName

public abstract void setDatabaseName(java.lang.String name)

getIndexNameDescriptor

@Nullable
public abstract java.lang.String getIndexNameDescriptor()

Returns the index name descriptor for the keys of this database. This descriptor is defined by StorableIndex, and it does not contain type information.

setIndexNameDescriptor

public abstract void setIndexNameDescriptor(java.lang.String descriptor)

getIndexTypeDescriptor

@Nullable
public abstract java.lang.String getIndexTypeDescriptor()

Returns the types of the index properties. This descriptor is defined by StorableIndex.

setIndexTypeDescriptor

public abstract void setIndexTypeDescriptor(java.lang.String descriptor)

getEvolutionStrategy

public abstract int getEvolutionStrategy()

Returns EVOLUTION_NONE if evolution of records is not supported.

setEvolutionStrategy

public abstract void setEvolutionStrategy(int strategy)

getCreationTimestamp

public abstract long getCreationTimestamp()

Returns the milliseconds from 1970-01-01T00:00:00Z when this record was created.

setCreationTimestamp

public abstract void setCreationTimestamp(long timestamp)

getVersionNumber

@Version
public abstract int getVersionNumber()

Record version number for this StoredDatabaseInfo instance. Some encoding strategies require a version number.

setVersionNumber

public abstract void setVersionNumber(int version)

getExtraData

@Nullable
public abstract byte[] getExtraData()

Since this record cannot evolve, this property allows it to be extended without conflicting with existing records. This record cannot evolve because an evolution strategy likely depends on this interface remaining stable, avoiding a cyclic dependency.

setExtraData

public abstract void setExtraData(byte[] data)
