Field Detail

TAG_NAME

public static final String TAG_NAME

Name of the tag.

See Also:

Constant Field Values

ATTRIBUTE_COND

public static final String ATTRIBUTE_COND

An ECMAScript expression which can be evaluated to true or false. If this attribute is present, it must evaluate to true for the transition to be selected. Note: You can not access the value of a the variable listed in the name attribute as it will not do the assign until the transition has been selected.

See Also:

Constant Field Values

ATTRIBUTE_EVENT

public static final String ATTRIBUTE_EVENT

This is a pattern that indicates a matching event type. Event types are dot-separated strings of arbitrary length. The character * is a wild-card, and will match zero or more characters of the processed event's type name.

See Also:

Constant Field Values

ATTRIBUTE_NAME

public static final String ATTRIBUTE_NAME

An ECMAScript left hand side expression evaluating to a previously defined variable. The value of the attribute will be set to the received event object. The event object can only be referenced by this name while executing the transition .

See Also:

Constant Field Values

ATTRIBUTE_STATE

public static final String ATTRIBUTE_STATE

This indicates the current possible state(s) of the eventprocessor . More than one state name may be specified, separated by white space.

See Also:

Constant Field Values

ATTRIBUTE_NAMES

protected static final ArrayList<String> ATTRIBUTE_NAMES

Supported attribute names for this node.
