Enum Constant Summary

Enum Constants

Enum Constant	Description
ACCEPT	Accept the diff to merge.
LEFT_TO_RIGHT	Merge from left to right.
REJECT	Reject the diff to merge.
RIGHT_TO_LEFT	Merge form right to left.

Method Summary

Modifier and Type	Method	Description
MergeOperation	getMergeAction(Diff difference, boolean isLeftEditable, boolean isRightEditable)	Returns the required action to be done to the given difference in this mode.
static MergeMode	getMergeMode(Diff diff, boolean leftEditable, boolean rightEditable)
DifferenceSource	getMergeTarget(boolean isLeftEditable, boolean isRightEditable)	Returns the target of the merge with the given condition about the left and right sides.
MergeMode	inverse()	Returns the inverse of this enum.
boolean	isLeftToRight(boolean isLeftEditable, boolean isRightEditable)	Returns if this mode will lead to merge to left to right depending whether left and/or right are editable.
boolean	isLeftToRight(Diff diff, boolean isLeftEditable, boolean isRightEditable)	To exactly know the way of merge (to compute consequences) we need the source of the diff.
static MergeMode	valueOf(String name)	Returns the enum constant of this class with the specified name.
static MergeMode[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Method Details

values

public static MergeMode[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static MergeMode valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

inverse

public MergeMode inverse()

Returns the inverse of this enum.

Returns:

the inverse of this enum.

getMergeTarget

public DifferenceSource getMergeTarget(boolean isLeftEditable,
 boolean isRightEditable)

Returns the target of the merge with the given condition about the left and right sides.

Parameters:

isLeftEditable - is the left side editable.

isRightEditable - is the right side editable.

Returns:

the target of the merge with the given condition about the left and right sides.

isLeftToRight

public boolean isLeftToRight(boolean isLeftEditable,
 boolean isRightEditable)

Returns if this mode will lead to merge to left to right depending whether left and/or right are editable.

Parameters:

isLeftEditable - is left side of the comparison editable.

isRightEditable - is right side of the comparison editable.

Returns:

if this mode will lead to merge to left to right depending whether left and/or right are editable.

isLeftToRight

public boolean isLeftToRight(Diff diff,
 boolean isLeftEditable,
 boolean isRightEditable)

To exactly know the way of merge (to compute consequences) we need the source of the diff.

Parameters:

diff - the diff to merge.

isLeftEditable - is left side of the comparison editable.

isRightEditable - is right side of the comparison editable.

Returns:

the way of merge.

getMergeAction

public MergeOperation getMergeAction(Diff difference,
 boolean isLeftEditable,
 boolean isRightEditable)

Returns the required action to be done to the given difference in this mode.

Parameters:

difference - the difference to analyze.

isLeftEditable - is left side of the comparison editable.

isRightEditable - is right side of the comparison editable.

Returns:

the required action to be done to the given difference in this mode.

getMergeMode

public static MergeMode getMergeMode(Diff diff,
 boolean leftEditable,
 boolean rightEditable)
