public class ValidEntryRuleInspector
extends XtextRuleInspector<Pair<java.lang.Boolean,java.lang.Boolean>,ParserRule>

Checks the entry rule for validity. A rule is considered to be a valid entry rule if it either accepts the empty input or if it ensures that a model is instantiated.

public ValidEntryRuleInspector(ValidationMessageAcceptor acceptor)

Method Detail

canInspect

protected boolean canInspect(ParserRule rule)

Overrides:

canInspect in class XtextRuleInspector<Pair<java.lang.Boolean,java.lang.Boolean>,ParserRule>

handleResult

protected void handleResult(Pair<java.lang.Boolean,java.lang.Boolean> r,
                            ParserRule rule)

Overrides:

handleResult in class XtextRuleInspector<Pair<java.lang.Boolean,java.lang.Boolean>,ParserRule>

caseCompoundElement

public Pair<java.lang.Boolean,java.lang.Boolean> caseCompoundElement(CompoundElement object)

Description copied from class: XtextSwitch

Returns the result of interpreting the object as an instance of 'Compound Element'. This implementation returns null; returning a non-null result will terminate the switch.

Overrides:

caseCompoundElement in class XtextSwitch<Pair<java.lang.Boolean,java.lang.Boolean>>

Parameters:

object - the target of the switch.

Returns:

the result of interpreting the object as an instance of 'Compound Element'.

Description copied from class: XtextSwitch

Returns the result of interpreting the object as an instance of 'Abstract Element'. This implementation returns null; returning a non-null result will terminate the switch.

Overrides:

caseAbstractElement in class XtextSwitch<Pair<java.lang.Boolean,java.lang.Boolean>>

Parameters:

object - the target of the switch.

Returns:

the result of interpreting the object as an instance of 'Abstract Element'.

See Also:

caseAction

public Pair<java.lang.Boolean,java.lang.Boolean> caseAction(Action object)

Description copied from class: XtextSwitch

Returns the result of interpreting the object as an instance of 'Action'. This implementation returns null; returning a non-null result will terminate the switch.

Overrides:

caseAction in class XtextSwitch<Pair<java.lang.Boolean,java.lang.Boolean>>

Parameters:

object - the target of the switch.

Returns:

the result of interpreting the object as an instance of 'Action'.

caseAlternatives

public Pair<java.lang.Boolean,java.lang.Boolean> caseAlternatives(Alternatives object)

Description copied from class: XtextSwitch

Returns the result of interpreting the object as an instance of 'Alternatives'. This implementation returns null; returning a non-null result will terminate the switch.

Overrides:

caseAlternatives in class XtextSwitch<Pair<java.lang.Boolean,java.lang.Boolean>>

Parameters:

object - the target of the switch.

Returns:

the result of interpreting the object as an instance of 'Alternatives'.

caseAssignment

public Pair<java.lang.Boolean,java.lang.Boolean> caseAssignment(Assignment object)

Description copied from class: XtextSwitch

Returns the result of interpreting the object as an instance of 'Assignment'. This implementation returns null; returning a non-null result will terminate the switch.

Overrides:

caseAssignment in class XtextSwitch<Pair<java.lang.Boolean,java.lang.Boolean>>

Parameters:

object - the target of the switch.

Returns:

the result of interpreting the object as an instance of 'Assignment'.

caseRuleCall

public Pair<java.lang.Boolean,java.lang.Boolean> caseRuleCall(RuleCall object)

Description copied from class: XtextSwitch

Returns the result of interpreting the object as an instance of 'Rule Call'. This implementation returns null; returning a non-null result will terminate the switch.

Overrides:

caseRuleCall in class XtextSwitch<Pair<java.lang.Boolean,java.lang.Boolean>>

Parameters:
