Associative array with the names of fields to be added as indexes of the array. The
value of each entry of the array should be set to another associative array with the
properties of the fields to be added. The properties of the fields should be the same
as defined by the Doctrine parser.
Associative array with the names of fields to be removed as indexes of the array.
Currently the values assigned to each entry are ignored. An empty array should be
used for future compatibility.
Associative array with the names of fields to be renamed as indexes of the array.
The value of each entry of the array should be set to another associative array with
the entry named name with the new field name and the entry named Declaration
that is expected to contain the portion of the field declaration already in DBMS
specific SQL code as it is used in the CREATE TABLE statement.
Associative array with the names of the fields to be changed as indexes of the
array. Keep in mind that if it is intended to change either the name of a field and
any other properties, the change array entries should have the new names of the
fields as array indexes.
The value of each entry of the array should be set to another associative array with the
properties of the fields to that are meant to be changed as array entries. These entries should
be assigned to the new values of the respective properties. The properties of the fields should
be the same as defined by the Doctrine parser.
