Creates an insert statement to insert entries into a specified entity set.

Type Parameters:

E - the type of the entity set

Parameters:

entity - the structured type representing the entity set

Returns:

the insert statement

into

static Insert into(String entityName,
                   UnaryOperator<StructuredType<?>> path)

Creates an insert statement to insert entries into a specified entity set.

Parameters:

entityName - the root entity name of the path expression

path - a path expression navigating from the root entity to the target entity of the insert statement

Returns:

the insert statement

into

static <E extends StructuredType<E>> Insert into(Class<E> entity)

Type Parameters:

E - the type of the entity set

Parameters:

entity - the static model representation of the entity set

Returns:

the insert statement

into

static <R extends StructuredType<R>,T extends StructuredType<T>> Insert into(Class<R> entity,
                                                                             Function<R,T> path)

the insert statement

into

static Insert into(CdsEntity entity)

Creates an insert statement to insert entries into a specified entity set.

Parameters:

entity - the model representation of the entity set obtained by reflection

Returns:

the insert statement

CdsModel.findEntity(String), CdsModel.entities()

copy

static Insert copy(CqnInsert insert)

Copies the given CqnInsert into an Insert builder.

Parameters:

insert - the CqnInsert to be copied

Returns:

the modifiable insert statement copy

cqn

static Insert cqn(String cqnInsert)

Creates an insert statement from a given CQN String.

Parameters:

cqnInsert - the CQN representation of the insert statement

Returns:

the insert statement

entries

Insert entries(Iterable<? extends Map<String,?>> entries)

Sets the entries to be inserted into the entity set.

Parameters:

entries - a collection of data where every element is the canonical representation

Returns:

the insert statement

entry

Insert entry(Map<String,?> entry)

Add a single entry to be inserted into the entity set. The data is given as a Map<String, Object> that maps element names of the target entity set to the values to be inserted.

The value can be deeply structured to represent a structured document:

• for single-valued relationships the value of the element is of type Map<String, Object>
• for collection-valued relationships the value of the element is of type List<Map<String, Object>>

Parameters:

entry - the data to be inserted as a map

Returns:

the insert statement

entry

Insert entry(String elementName,
             Object value)

Add a single entry to be inserted into the entity set.

The value can be deeply structured to represent a structured document:

• for single-valued relationships the value of the element is of type Map<String, Object>
• for collection-valued relationships the value of the element is of type List<Map<String, Object>>

Parameters:

elementName - the element name of the target entity for the value to be inserted

value - the data to be inserted for the element

Returns:

the insert statement
