Enum CoercionInputShape

java.lang.Enum<CoercionInputShape>

com.fasterxml.jackson.databind.cfg.CoercionInputShape

All Implemented Interfaces:

Serializable, Comparable<CoercionInputShape>

public enum CoercionInputShape
extends Enum<CoercionInputShape>

Set of input types (which mostly match one of JsonToken types) used for configuring CoercionActions to take when reading input into target types (specific type or LogicalType). Contains both physical input shapes (which match one of JsonToken types) and a few logical input shapes ("empty" variants).

Note that null input shape is explicitly not included as its configuration is distinct from other types.

Enum Constant Summary

Enum Constants

Enum Constant	Description
Array	Shape of Array values from input (token sequence from JsonToken.START_ARRAY to JsonToken.END_ARRAY)
Binary	Shape of binary data values from input, if expressed natively by underlying format (many textual formats, including JSON, do not have such shape); if so generally seen as JsonToken.VALUE_EMBEDDED_OBJECT.
Boolean	Shape of boolean values from input (tokens JsonToken.VALUE_TRUE and JsonToken.VALUE_FALSE)
EmptyArray	Special case of Array values with no actual content (sequence of 2 tokens: JsonToken.START_ARRAY, JsonToken.END_ARRAY): usually used to allow special coercion into "empty" or null target type.
EmptyObject	Special case of Object values with no actual content (sequence of 2 tokens: JsonToken.START_OBJECT, JsonToken.END_OBJECT): usually used to allow special coercion into "empty" or null target type.
EmptyString	Special case for String values with no content (or, if allowed by format or specific configuration, also "blank" String, that is, all-whitespace content).
Float	Shape of floating point (non-integral) numeric values from input (token JsonToken.VALUE_NUMBER_FLOAT)
Integer	Shape of integral (non-floating point) numeric values from input (token JsonToken.VALUE_NUMBER_INT)
Object	Shape of Object values from input (token sequence from JsonToken.START_OBJECT to JsonToken.END_OBJECT)
String	Shape of string values from input (tokens JsonToken.VALUE_STRING)

Binary

public static final CoercionInputShape Binary

Shape of binary data values from input, if expressed natively by underlying format (many textual formats, including JSON, do not have such shape); if so generally seen as JsonToken.VALUE_EMBEDDED_OBJECT.

EmptyString

Method Detail

values

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

Returns:

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

valueOf

public static CoercionInputShape 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
