Method Details

values

public static DynamoDbComparisonType[] values()

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

Returns:

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

valueOf

public static DynamoDbComparisonType 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

fromToken

public static DynamoDbComparisonType fromToken(String token)

Maps a DynamoDB comparator token to a normalized comparison type.

Parameters:

token - comparator token from parsed expression

Returns:

normalized comparison type

toOperation

public abstract ComparisonOperation<?> toOperation(String fieldName,
 Object value)

Creates a comparison operation instance for this comparison type.

Parameters:

fieldName - field name coming from DynamoDB expression/condition

value - comparison value

Returns:

concrete comparison operation

fromOperation

public static DynamoDbComparisonType fromOperation(ComparisonOperation<?> operation)

Maps a comparison operation back to its normalized comparison type.

Parameters:

operation - comparison operation instance

Returns:

associated comparison type

invert

public abstract DynamoDbComparisonType invert()

Returns the inverse of the current comparator.

Returns:

inverse comparison type

matchesOperation

protected abstract boolean matchesOperation(ComparisonOperation<?> operation)

Checks whether the given operation corresponds to this normalized comparison type.

Parameters:

operation - comparison operation instance

Returns:

whether the operation belongs to this comparison type
