Method Summary

Modifier and Type	Method and Description
static TokenInTrapStateQuerySpecification	instance()
TokenInTrapStateMatcher	instantiate() For backward compatibility of code generated with previous versions of viatra query, this method has a default implementation returning null, indicating that a matcher can only be created using the old method, which ignores the hints provided by the user.
protected TokenInTrapStateMatcher	instantiate(ViatraQueryEngine engine)
TokenInTrapStateMatch	newEmptyMatch() Returns an empty, mutable Match compatible with matchers of this query.
TokenInTrapStateMatch	newMatch(java.lang.Object... parameters) Returns a new (partial) Match object compatible with matchers of this query.

Method Detail

instance

public static TokenInTrapStateQuerySpecification instance()
                                                   throws ViatraQueryException

Returns:

the singleton instance of the query specification

Throws:

ViatraQueryException - if the pattern definition could not be loaded

instantiate

protected TokenInTrapStateMatcher instantiate(ViatraQueryEngine engine)
                                       throws ViatraQueryException

Specified by:

instantiate in class BaseQuerySpecification<TokenInTrapStateMatcher>

Throws:

ViatraQueryException

instantiate

public TokenInTrapStateMatcher instantiate()
                                    throws ViatraQueryException

Description copied from class: BaseQuerySpecification

For backward compatibility of code generated with previous versions of viatra query, this method has a default implementation returning null, indicating that a matcher can only be created using the old method, which ignores the hints provided by the user.

Specified by:

instantiate in interface IQuerySpecification<TokenInTrapStateMatcher>

Overrides:

instantiate in class BaseQuerySpecification<TokenInTrapStateMatcher>

Throws:

ViatraQueryException

newEmptyMatch

public TokenInTrapStateMatch newEmptyMatch()

Description copied from interface: IQuerySpecification

Returns an empty, mutable Match compatible with matchers of this query. Fields of the mutable match can be filled to create a partial match, usable as matcher input. This can be used to call the matcher with a partial match even if the specific class of the matcher or the match is unknown.

Returns:

the empty match

newMatch

public TokenInTrapStateMatch newMatch(java.lang.Object... parameters)

Description copied from interface: IQuerySpecification

Returns a new (partial) Match object compatible with matchers of this query. This can be used e.g. to call the matcher with a partial match.

The returned match will be immutable. Use IQuerySpecification.newEmptyMatch() to obtain a mutable match object.

Parameters:

parameters - the fixed value of pattern parameters, or null if not bound.

Returns:

the (partial) match object.
