Enum Constant Detail

EXACT_MATCH

public static final ResolutionStatus EXACT_MATCH

Column was successfully resolved to exactly one source. The resolution is unambiguous and confident.

AMBIGUOUS

public static final ResolutionStatus AMBIGUOUS

Column has multiple possible sources (ambiguous). Multiple tables contain columns with the same name. Candidates are ranked by confidence.

NOT_FOUND

public static final ResolutionStatus NOT_FOUND

Column could not be resolved to any source. No matching column was found in any visible table.

Method Detail

values

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

Returns:

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

valueOf

public static ResolutionStatus 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
