public static enum ERXCopyable.CopyType
extends Enum<ERXCopyable.CopyType>

Enum that specifies the valid ways in which an EOModel's EOPropertys can be copied.

The ERXCopyable.CopyType is specified for a given EOProperty using a String entry in the property's UserInfo dictionary with a key of ERXCopyable.CopyType and a value matching (case-insensitively) one of the elements of this enum.

Enum Constant Detail

SKIP

public static final ERXCopyable.CopyType SKIP

Stored as " ERXCopyable.CopyType = Skip;" in the property's UserInfo dictionary. Skips the value. For attributes only.

NULLIFY

public static final ERXCopyable.CopyType NULLIFY

Stored as " ERXCopyable.CopyType = Nullify;" in the property's UserInfo dictionary. Sets the copy's value to null. This setting does not copy the original's value. For attributes and relationships.

REFERENCE

public static final ERXCopyable.CopyType REFERENCE

Stored as " ERXCopyable.CopyType = Reference;" in the EOAttribute 's and EORelationship's UserInfo dictionary. For attributes this simply sets the same value on the destination as the source. For relationships, this sets the copy's relationship to point to the same destination object as the original's relationship does. WARNING: if you use this on a non-flattening, to-many relationship, the destination objects will be moved from the original to the copy. For attributes and relationships.

SHALLOW

public static final ERXCopyable.CopyType SHALLOW

Stored as " ERXCopyable.CopyType = Shallow;" in the EORelationship's UserInfo dictionary. New instances of the destination ERXCopyable objects will be made and all of the original's attributes and relationships will be reference copied. For relationships only.

DEEP

public static final ERXCopyable.CopyType DEEP

Stored as " ERXCopyable.CopyType = Deep;" in the EORelationship's UserInfo dictionary. Duplicates each of the destination ERXCopyable objects using their implementation of the ERXCopyable.duplicate(NSMutableDictionary) method. For relationships only.

CURRENT_TIMESTAMP

public static final ERXCopyable.CopyType CURRENT_TIMESTAMP

Stored as " ERXCopyable.CopyType = CurrentTimestamp;" in the EOAttribute's UserInfo dictionary. This setting does not copy the original's value. It sets the copy's value to the current date and time using new NSTimestamp() For attributes only.

UUID

public static final ERXCopyable.CopyType UUID

Stored as " ERXCopyable.CopyType = UUID;" in the EOAttribute's UserInfo dictionary. This setting does not copy the original's value. It sets the copy's value to a newly generated UUID using UUID.randomUUID() For attributes only.

Method Detail

values

public static ERXCopyable.CopyType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ERXCopyable.CopyType c : ERXCopyable.CopyType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ERXCopyable.CopyType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

type

public String type()

copyTypesFor

public static NSArray<ERXCopyable.CopyType> copyTypesFor(EOProperty property)

Parameters:

property - the attribute or relationship being copied

Returns:

an array of the valid ERXCopyable.CopyTypes for the passed-in EOProperty

get

public static ERXCopyable.CopyType get(String typeAsString)

Parameters:

typeAsString - a String to match (case-insensitive) to a ERXCopyable.CopyType

Returns:

the ERXCopyable.CopyType equivalent to the typeAsString
