INTERNAL:

Specified by:

addFieldsToRow in interface MultitenantPolicy

addToTableDefinition

public void addToTableDefinition(TableDefinition tableDefinition)

INTERNAL:

Specified by:

addToTableDefinition in interface MultitenantPolicy

clone

public MultitenantPolicy clone(ClassDescriptor descriptor)

INTERNAL: Multitenant policies are cloned per inheritance subclass.

Specified by:

clone in interface MultitenantPolicy

getContextProperty

public java.lang.String getContextProperty()

INTERNAL: Return the context property for this table per tenant policy.

getTable

public DatabaseTable getTable(java.lang.String tableName)

INTERNAL: Return the new database table associated with this tenant.

getTable

public DatabaseTable getTable(DatabaseTable table)

INTERNAL: Return the new database table associated with this tenant.

getTableName

protected java.lang.String getTableName(DatabaseTable table,
                                        java.lang.String tenant)

INTERNAL: Return the tenant table name.

hasContextTenant

public boolean hasContextTenant()

INTERNAL: Return true if the tenant has been set for this policy.

initialize

public void initialize(AbstractSession session)
                throws DescriptorException

INTERNAL:

Specified by:

initialize in interface MultitenantPolicy

Throws:

DescriptorException

isPrefixPerTable

public boolean isPrefixPerTable()

PUBLIC: Return true if this descriptor requires a prefix to the table per tenant.

isSchemaPerTable

public boolean isSchemaPerTable()

PUBLIC: Return true if this descriptor requires a table schema per tenant.

isSingleTableMultitenantPolicy

public boolean isSingleTableMultitenantPolicy()

INTERNAL:

Specified by:

isSingleTableMultitenantPolicy in interface MultitenantPolicy

isSchemaPerMultitenantPolicy

public boolean isSchemaPerMultitenantPolicy()

INTERNAL:

Specified by:

isSchemaPerMultitenantPolicy in interface MultitenantPolicy

isSuffixPerTable

public boolean isSuffixPerTable()

PUBLIC: Return true if this descriptor requires a suffix to the table per tenant.

isTablePerMultitenantPolicy

public boolean isTablePerMultitenantPolicy()

INTERNAL:

Specified by:

isTablePerMultitenantPolicy in interface MultitenantPolicy

postInitialize

public void postInitialize(AbstractSession session)

INTERNAL:

Specified by:

postInitialize in interface MultitenantPolicy

preInitialize

public void preInitialize(AbstractSession session)
                   throws DescriptorException

INTERNAL:

Specified by:

preInitialize in interface MultitenantPolicy

Throws:

DescriptorException

setTenantTableDiscriminatorType

public void setTenantTableDiscriminatorType(TenantTableDiscriminatorType type)

PUBLIC: Set the tenant table discriminator type.

setContextProperty

public void setContextProperty(java.lang.String contextProperty)

PUBLIC: Set the context property used to define the table per tenant. If it is not set by the user, the policy defaults it to the multitenant property default of "eclipselink.tenant-id"

setTablePerTenant

protected void setTablePerTenant()

INTERNAL: This method is used to update the table per tenant descriptor with a table per tenant prefix or suffix on its associated tables. This includes any relation tables from mappings. If the given session is a client session than we must clone the tables. Outside of a client session, assume global usage and no cloning is needed. This method should only be called at the start of a client session lifecycle and should only be called once.

setTableSchemaPerTenant

protected void setTableSchemaPerTenant()

INTERNAL: This method is used to update the table per tenant descriptor with a table per tenant schema. This includes any relation tables from mappings. This will be done through the setting of a table qualifier on the tables. This method should only be called at the start of a client session lifecycle and should only be called once.

setContextTenant

public void setContextTenant(java.lang.String contextTenant)

INTERNAL:

shouldInitialize

public boolean shouldInitialize(AbstractSession session)

INTERNAL: This method is called during regular descriptor initialization. When initializing at that level no cloning should be done on when setting the context tenant.

updateTable

protected DatabaseTable updateTable(DatabaseTable table)

INTERNAL: This method will update the table by cloning it and setting a new name on it. The table association will be stored here as well for ease of future look up.

usesContextProperty

public boolean usesContextProperty(java.lang.String property)

INTERNAL: Return true if this policy accepts the given property.
