Enum InitializationPriority

java.lang.Object

java.lang.Enum<InitializationPriority>

org.apache.tapestry5.services.javascript.InitializationPriority

All Implemented Interfaces:

Serializable, Comparable<InitializationPriority>

public enum InitializationPriority
extends Enum<InitializationPriority>

Sets the priority for JavaScript initialization scripting. InitializationPriority allows coarse-grained control over the order in which initialization occurs on the client. The default is normally NORMAL. Starting in 5.4, these values have less meaning, as the dynamic loading of modules may have unexpected effects on the exact order in which initialization occurs as some initializations may be deferred until a referenced module, or a dependency of a referenced module, has been loaded.

Since:

5.2.0

Enum Constant Summary

Enum Constants

Enum Constant	Description
EARLY	All early execution occurs before NORMAL.
IMMEDIATE	Deprecated. Deprecated in 5.4; this is now treated as "earlier than early".
LATE	Execution occurs after NORMAL.
NORMAL	This is the typical priority.

Method Summary

Modifier and Type	Method	Description
static InitializationPriority	valueOf(String name)	Returns the enum constant of this type with the specified name.
static InitializationPriority[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

IMMEDIATE

public static final InitializationPriority IMMEDIATE

Deprecated.

Deprecated in 5.4; this is now treated as "earlier than early".

Provided JavaScript will be executed immediately (it is not deferred until the page loads). Execution occur via JavaScript's eval, and occurs once all JavaScript libraries (but not modules) for the page have been loaded.

EARLY

public static final InitializationPriority EARLY

All early execution occurs before NORMAL.

NORMAL

public static final InitializationPriority NORMAL

This is the typical priority.

LATE

public static final InitializationPriority LATE

Execution occurs after NORMAL.

Method Detail

values

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

Returns:

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

valueOf

public static InitializationPriority 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
