Enum JSONDateFormat

java.lang.Enum<JSONDateFormat>

com.smartgwt.client.types.JSONDateFormat

All Implemented Interfaces:

ValueEnum, java.io.Serializable, java.lang.Comparable<JSONDateFormat>

public enum JSONDateFormat
extends java.lang.Enum<JSONDateFormat>
implements ValueEnum

Format for encoding dates in JSON. Note you can override JSONEncoder.encodeDate() for a custom format.

Enum Constant Summary

Enum Constants

Enum Constant and Description
DATE_CONSTRUCTOR dates are encoded as raw JavaScript code for creating a Date object, that is:
LOGICAL_DATE_CONSTRUCTOR serializes Date instances in a way that preserves the distinction between logical dates, logical times, and full datetime values, as explained here.
XML_SCHEMA dates are is encoded as a String in XML Schema date format in UTC, for example, "2005-08-02" for logical date fields or "2005-08-01T21:35:48.350" for datetime fields.

Enum Constant Detail

XML_SCHEMA

public static final JSONDateFormat XML_SCHEMA

dates are is encoded as a String in XML Schema date format in UTC, for example, "2005-08-02" for logical date fields or "2005-08-01T21:35:48.350" for datetime fields. See Date format and\n storage for more information.

If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "xmlSchema".

DATE_CONSTRUCTOR

public static final JSONDateFormat DATE_CONSTRUCTOR

dates are encoded as raw JavaScript code for creating a Date object, that is:

  new Date(1238792738633)
  

This is not strictly valid JSON, but if eval()d, will result in an identical date object, regardless of timezone. However, it does not preserve the distinction between logical dates vs full datetime values - use "logicalDateConstructor" mode for that.

If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "dateConstructor".

LOGICAL_DATE_CONSTRUCTOR

public static final JSONDateFormat LOGICAL_DATE_CONSTRUCTOR

serializes Date instances in a way that preserves the distinction between logical dates, logical times, and full datetime values, as explained here. Like 'dateConstructor' mode, this does not produce strictly valid JSON, and instead embeds JavaScript calls.

In addition, unlike 'dateConstructor' mode, using eval() to reconstruct the original JavaScript objects will only work in the presence of Smart GWT, and not just in a generic JavaScript interpreter.

If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "logicalDateConstructor".

Method Detail

values

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

Returns:

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

valueOf

public static JSONDateFormat 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

getValue

public java.lang.String getValue()

Specified by:

getValue in interface ValueEnum
