Method Detail

isFeatureSupported

protected static boolean isFeatureSupported(UUID feature,
                                            UUID actualUuid)

Determines if a particular serialized representation of an ATN supports a particular feature, identified by the UUID used for serializing the ATN at the time the feature was first introduced.

Parameters:

feature - The UUID marking the first time the feature was supported in the serialized ATN.

actualUuid - The UUID of the actual serialized ATN which is currently being deserialized.

Returns:

true if the actualUuid value represents a serialized ATN at or after the feature identified by feature was introduced; otherwise, false.

deserialize

public ATN deserialize(char[] data)

markPrecedenceDecisions

protected void markPrecedenceDecisions(ATN atn)

Analyze the StarLoopEntryState states in the specified ATN to set the StarLoopEntryState.isPrecedenceDecision field to the correct value.

Parameters:

atn - The ATN.

verifyATN

protected void verifyATN(ATN atn)

checkCondition

protected void checkCondition(boolean condition)

checkCondition

protected void checkCondition(boolean condition,
                              String message)
