Method Details

column

<B extends ColumnDefinition.Builder<T,
B>>
ColumnDefinition.Builder<T,B> column()

Creates a new ColumnDefinition.Builder instance.

Type Parameters:

B - the builder type

Returns:

a new ColumnDefinition.Builder

primaryKey

<B extends ColumnDefinition.Builder<T,
B>>
ColumnDefinition.Builder<T,B> primaryKey()

Returns a new ColumnDefinition.Builder instance, with the primary key index 0. Note that this renders this column non-null and non-updatable by default, this can be reverted by setting it as updatable and/or nullable after defining a primary key column.

   ...
   .primaryKey()
   .nullable(true)
   .updatable(true)
 

Type Parameters:

B - the builder type

Returns:

a new ColumnDefinition.Builder with primary key index 0

See Also:

• AttributeDefinition.Builder.nullable(boolean)
• ColumnDefinition.Builder.updatable(boolean)

primaryKey

<B extends ColumnDefinition.Builder<T,
B>>
ColumnDefinition.Builder<T,B> primaryKey(int index)

Returns a new ColumnDefinition.Builder instance, with the given primary key index. Note that this renders this column non-null and non-updatable by default, this can be reverted by setting it as updatable and/or nullable after defining a primary key column.

   ...
   .primaryKey()
   .nullable(true)
   .updatable(true)
 

Type Parameters:

B - the builder type

Parameters:

index - the zero-based index of this column in the primary key

Returns:

a new ColumnDefinition.Builder with the given primary key index

Throws:

IllegalArgumentException - in case index is a negative number

See Also:

• AttributeDefinition.Builder.nullable(boolean)
• ColumnDefinition.Builder.updatable(boolean)

subquery

<B extends ColumnDefinition.Builder<T,
B>>
ColumnDefinition.Builder<T,B> subquery(String subquery)

Creates a new ColumnDefinition.Builder instance, based on a subquery.

Type Parameters:

B - the builder type

Parameters:

subquery - the sql query

Returns:

a new ColumnDefinition.Builder

booleanColumn

<C,

Creates a new BlobColumnDefinition.Builder instance.

Returns:

a new BlobColumnDefinition.Builder

Throws:

IllegalStateException - in case this columnn is note a byte array column
