Method Detail

createRecord

default RecordHolder createRecord(RecordType type)

Creates new record with given type. The record fields are not initialized.

Parameters:

type -

Returns:

new record with given type

Throws:

NullPointerException - if type is null

createExternalRecordProxy

RecordHolder createExternalRecordProxy(RecordType type,
                                       RecordHolder proxySet)

Creates a proxy without proxied record. It can be used only for shared records. When merged a shared record is created. If proxySet is null it creates proxy on level 1. If a proxy set is specified, it creates proxy on the level of the proxy set and adds it to the proxy set.

Parameters:

type -

proxySet -

Returns:

proxy without proxied record

createRecord

RecordHolder createRecord(RecordType type,
                          Map<String,?> values)

Creates new record with given type.

Parameters:

type -

values - initial record field values

Returns:

new record with given type

Throws:

NullPointerException - if type or values is null

IllegalArgumentException - if values are not assignable to the record field types

createNonSharedRecord

RecordHolder createNonSharedRecord(RecordType type,
                                   Map<String,?> values)

Creates new record of given type. The record is always created non persistent, even if the record type is shared. Use this carefully, since this may result in many non shared instances of shared record types swarming in the model context and may cause a lot of exceptional behavior, e.g. when trying to assign not persistent object as a member of association of some other shared instance.

Parameters:

type -

values - initial record field values

Returns:

new record with given type

Throws:

NullPointerException - if type or values is null

IllegalArgumentException - if values are not assignable to the record field types

createRecord

default RecordHolder createRecord(String type)

Creates new record with given type. The type must be a fully qualified name. The record fields are not initialized.

Parameters:

type -

Returns:

new record with given type

Throws:

NullPointerException - if type is null

IllegalArgumentException - if no such type exists

RecordType

createRecord

RecordHolder createRecord(String type,
                          Map<String,?> values)

Creates new record with given type. The type must be a fully qualified name.

Parameters:

type -

values - initial record field values

Returns:

new record with given type

Throws:

NullPointerException - if type is null

IllegalArgumentException - if no such type exists or if values are not assignable to the record field types

See Also:

RecordType

createList

ListHolder createList(Collection<?> values)

Creates new list with given values (ListHolders are immutable). The type is inferred from the types of the values.

Parameters:

values -

Returns:

new list

Throws:

NullPointerException - if values is null

IllegalArgumentException - if values are not of a valid type

createRange

ListHolder createRange(long first,
                       long last)

Creates a range (list) defined by endpoints (both inclusive).

If first <= last, the range contains elements first, first + 1, ..., last.

If first > last, the range contains elements first, first - 1, ..., last.

The memory footprint of range in constant (only endpoints and size is stored, not all elements).

Parameters:

first -

last -

Returns:

the created list

Throws:

NullPointerException - if values is null

IllegalArgumentException - if values are not of a valid type

createSet

SetHolder createSet(Collection<?> values)

Creates new set with given values (SetHolders are immutable). The type is inferred from the types of the values.

Parameters:

values -

Returns:

new list

Throws:

NullPointerException - if values is null

IllegalArgumentException - if values are not of a valid type

createMap

MapHolder createMap(List<?> keys,
                    List<?> values)

Creates new map with given values (MapHolders are immutable). The type is inferred from the types of the values.

Parameters:

keys - a list of keys

values - a list of values

Returns:

new map

Throws:

NullPointerException - if keys or values is null

createMap

default MapHolder createMap(Map<?,?> map)

Creates new map with given values (MapHolders are immutable). The type is inferred from the types of the values.

Parameters:

map -

Returns:

new map

Throws:

NullPointerException - if map is null

createClosure
