Enum Constant Summary

Enum Constants

Enum Constant and Description
OVER_SPECIFIED The reason a coder could not be provided is because the type variable T is over specified with multiple incompatible coders.
TYPE_ERASURE The reason a coder could not be provided is type erasure, for example when requesting coder inference for a List<T> where T is unknown.
UNKNOWN The reason a coder could not be provided is unknown or does not have an established CannotProvideCoderException.ReasonCode.

Enum Constant Detail

UNKNOWN

public static final CannotProvideCoderException.ReasonCode UNKNOWN

The reason a coder could not be provided is unknown or does not have an established CannotProvideCoderException.ReasonCode.

TYPE_ERASURE

public static final CannotProvideCoderException.ReasonCode TYPE_ERASURE

The reason a coder could not be provided is type erasure, for example when requesting coder inference for a List<T> where T is unknown.

OVER_SPECIFIED

public static final CannotProvideCoderException.ReasonCode OVER_SPECIFIED

The reason a coder could not be provided is because the type variable T is over specified with multiple incompatible coders.

Method Detail

values

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

Returns:

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

valueOf

public static CannotProvideCoderException.ReasonCode valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
