Class WriteMode

java.lang.Object

com.dropbox.core.v2.files.WriteMode

public final class WriteMode
extends Object

Your intent when writing a file to some path. This is used to determine what constitutes a conflict and what the autorename strategy is. In some situations, the conflict behavior is identical: (a) If the target path doesn't contain anything, the file is always written; no conflict. (b) If the target path contains a folder, it's always a conflict. (c) If the target path contains a file with identical contents, nothing gets written; no conflict. The conflict checking differs in the case where there's a file at the target path with contents different from the contents you're trying to write.

This class is a tagged union. Tagged unions instances are always associated to a specific tag. This means only one of the isAbc() methods will return true. You can use tag() to determine the tag associated with this instance.

Field Detail

ADD

public static final WriteMode ADD

Never overwrite the existing file. The autorename strategy is to append a number to the file name. For example, "document.txt" might become "document (2).txt".

OVERWRITE

public static final WriteMode OVERWRITE

Always overwrite the existing file. The autorename strategy is the same as it is for ADD.

Method Detail

tag

public WriteMode.Tag tag()

Returns the tag for this instance.

This class is a tagged union. Tagged unions instances are always associated to a specific tag. This means only one of the isXyz() methods will return true. Callers are recommended to use the tag value in a switch statement to properly handle the different values for this WriteMode.

Returns:

the tag for this instance.

isAdd

public boolean isAdd()

Returns true if this instance has the tag WriteMode.Tag.ADD, false otherwise.

Returns:

true if this instance is tagged as WriteMode.Tag.ADD, false otherwise.

isOverwrite

public boolean isOverwrite()

Returns true if this instance has the tag WriteMode.Tag.OVERWRITE, false otherwise.

Returns:

true if this instance is tagged as WriteMode.Tag.OVERWRITE, false otherwise.

isUpdate

public boolean isUpdate()

Returns true if this instance has the tag WriteMode.Tag.UPDATE, false otherwise.

Returns:

true if this instance is tagged as WriteMode.Tag.UPDATE, false otherwise.

update

public static WriteMode update(String value)

Returns an instance of WriteMode that has its tag set to WriteMode.Tag.UPDATE.

Overwrite if the given "rev" matches the existing file's "rev". The autorename strategy is to append the string "conflicted copy" to the file name. For example, "document.txt" might become "document (conflicted copy).txt" or "document (Panda's conflicted copy).txt".

Parameters:

value - value to assign to this instance.

Returns:

Instance of WriteMode with its tag set to WriteMode.Tag.UPDATE.

Throws:

IllegalArgumentException - if value is shorter than 9, does not match pattern "[0-9a-f]+", or is null.

getUpdateValue

public String getUpdateValue()

Overwrite if the given "rev" matches the existing file's "rev". The autorename strategy is to append the string "conflicted copy" to the file name. For example, "document.txt" might become "document (conflicted copy).txt" or "document (Panda's conflicted copy).txt".

This instance must be tagged as WriteMode.Tag.UPDATE.

Returns:

The update(java.lang.String) value associated with this instance if isUpdate() is true.

Throws:

IllegalStateException - If isUpdate() is false.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object

toStringMultiline

public String toStringMultiline()

Returns a String representation of this object formatted for easier readability.

The returned String may contain newlines.

Returns:

Formatted, multiline String representation of this object
