Enum GitPositionTransformer.BestPositionOnConflict

java.lang.Object

java.lang.Enum<GitPositionTransformer.BestPositionOnConflict>

com.google.gerrit.server.patch.GitPositionTransformer.BestPositionOnConflict

All Implemented Interfaces:

GitPositionTransformer.PositionConflictStrategy, Serializable, Comparable<GitPositionTransformer.BestPositionOnConflict>

Enclosing class:

GitPositionTransformer

public static enum GitPositionTransformer.BestPositionOnConflict
extends Enum<GitPositionTransformer.BestPositionOnConflict>
implements GitPositionTransformer.PositionConflictStrategy

A strategy which tries to select the next suitable GitPositionTransformer.Position on a conflicting mapping. At the moment, this strategy is very basic and only defers to the next higher level (e.g. range unclear -> drop range but keep file reference). This could be improved in the future.

We need this strategy for ported comments.

Warning: With this strategy, mapped GitPositionTransformer.Positions are not guaranteed to refer to exactly the same commit content as before. See more details at GitPositionTransformer.PositionConflictStrategy.

Contract: This strategy will never drop any GitPositionTransformer.Position.

Method Summary

Modifier and Type	Method	Description
Optional<GitPositionTransformer.Position>	getOnFileConflict(GitPositionTransformer.Position oldPosition)	Determines an alternate GitPositionTransformer.Position when there is no file for the position (= file deletion) in the target tree.
Optional<GitPositionTransformer.Position>	getOnRangeConflict(GitPositionTransformer.Position oldPosition)	Determines an alternate GitPositionTransformer.Position when the range of the position can't be mapped without a conflict.
static GitPositionTransformer.BestPositionOnConflict	valueOf(String name)	Returns the enum constant of this type with the specified name.
static GitPositionTransformer.BestPositionOnConflict[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Method Detail

values

public static GitPositionTransformer.BestPositionOnConflict[] 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 (GitPositionTransformer.BestPositionOnConflict c : GitPositionTransformer.BestPositionOnConflict.values())
    System.out.println(c);

Returns:

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

valueOf

public static GitPositionTransformer.BestPositionOnConflict 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

getOnRangeConflict

public Optional<GitPositionTransformer.Position> getOnRangeConflict(GitPositionTransformer.Position oldPosition)

Description copied from interface: GitPositionTransformer.PositionConflictStrategy

Determines an alternate GitPositionTransformer.Position when the range of the position can't be mapped without a conflict.

Specified by:

getOnRangeConflict in interface GitPositionTransformer.PositionConflictStrategy

Parameters:

oldPosition - position in the source tree

Returns:

the new GitPositionTransformer.Position or an empty Optional if the position should be dropped

getOnFileConflict

public Optional<GitPositionTransformer.Position> getOnFileConflict(GitPositionTransformer.Position oldPosition)

Description copied from interface: GitPositionTransformer.PositionConflictStrategy

Determines an alternate GitPositionTransformer.Position when there is no file for the position (= file deletion) in the target tree.

Specified by:

getOnFileConflict in interface GitPositionTransformer.PositionConflictStrategy

Parameters:

oldPosition - position in the source tree

Returns:

the new GitPositionTransformer.Position or an empty Optional if the position should be * dropped
