Enum Constant Summary

Enum Constants

Enum Constant	Description
COMPATIBILITY	This is the pre version 5.21 mode: field expressions are allowed and the only way to inject values.
DISABLED	(Advised mode, as it is the safest) Disables field injection when using delegateExpressions, no field injection will happen.
MIXED	Allows injection when using delegateExpressions but will not throw an exception when the fields are not defined on the delegate.

Method Summary

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

Enum Constant Detail

COMPATIBILITY

public static final DelegateExpressionFieldInjectionMode COMPATIBILITY

This is the pre version 5.21 mode: field expressions are allowed and the only way to inject values. Using the DelegateHelper.getField(org.activiti.engine.delegate.DelegateExecution, String) method is not possible when using this mode, unless the Expressions are still defined as members of the delegate (otherwise an exception will be thrown). In that case, they should not be used, but rather the DelegateHelper methods should be used.

MIXED

public static final DelegateExpressionFieldInjectionMode MIXED

Allows injection when using delegateExpressions but will not throw an exception when the fields are not defined on the delegate. This allows for mixed behaviours where some delegates have injection (for example because they are not singletons) and some don't.

DISABLED

public static final DelegateExpressionFieldInjectionMode DISABLED

(Advised mode, as it is the safest) Disables field injection when using delegateExpressions, no field injection will happen.

Method Detail

values

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

Returns:

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

valueOf

public static DelegateExpressionFieldInjectionMode 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
