Method Detail

getTable

DataTable getTable()

Returns:

the table this entity fields maps to

getTableFields

java.util.stream.Stream<org.jooq.TableField<org.jooq.Record,?>> getTableFields()

Returns:

the table fields this entity field maps to

getFirstTableField

default org.jooq.TableField<org.jooq.Record,?> getFirstTableField()

Returns:

the first table field that this entity field maps to

Throws:

java.lang.IllegalStateException - if there are no fields

getDbValues

java.util.stream.Stream<java.lang.Object> getDbValues(T value)

Parameters:

value - value of entity field to translate

Returns:

the values for the fields returned by getTableFields(), in the same order

getFirstDbValue

default java.lang.Object getFirstDbValue(T value)

Parameters:

value - value of entity field to translate

Returns:

the first value for the fields returned by getTableFields(), in field order

Throws:

java.lang.IllegalStateException - if there are no fields

getFromRecord

T getFromRecord(java.util.Iterator<java.lang.Object> valuesIterator)

Composes the value of the entity field out of values of individual table fields. The iterator passed to this method is positioned at the value of the first field returned by getTableFields() and the following values correspond to the rest of the fields in the same order.

Parameters:

valuesIterator - iterator positioned at the start of values for getTableFields()

Returns:

the value of entity field composed out of DB values taken from the supplied iterator

isIdentityField

default boolean isIdentityField()
