Method Detail

setId

static <T extends Entity> T setId(T entity,
                                  UUID id)

getTableName

static <T extends Entity> String getTableName(Class<T> entity)

getColumns

static <T extends Entity> String[] getColumns(Class<T> clasz)

getColumnsWithoutId

static <T extends Entity> String[] getColumnsWithoutId(Class<T> clasz)

column

static <T extends Entity> String column(Class<T> entityClass,
                                        String column)

toJson

static <T extends Entity> io.vertx.core.json.JsonObject toJson(T entity)

fromJson

static <T extends Entity> T fromJson(io.vertx.core.json.JsonObject json,
                                     Class<T> entityClass)

merge

static <T extends Entity> T merge(T from,
                                  T to)

Merges the field values of to onto from, replacing from's value with to's non-null value. If to's value for a certain field is null, resulting return object will take from's value for that field.

This does not mutate the original objects.

Type Parameters:

T - Entity.class object should conform to Table.class and Column.class

Parameters:

from - object to replace values with

to - object whose values will be used to replace from's

Returns:

the resulting Entity object.
