Method Details

needsWrapperFor

public boolean needsWrapperFor(Type<?> type)

Description copied from interface: CompiletimeModel

Determines whether a value of the given type has to be wrapped before it is added as a node to a Graph.

Specified by:

needsWrapperFor in interface CompiletimeModel

Parameters:

type - a value type

Returns:

true iff a wrapper is needed for type

getEdgeTypeFor

public Type<?> getEdgeTypeFor(Type<?> type)

Description copied from interface: CompiletimeModel

Specifies the compile-time type of edges for a given type. This method returns the type to which an expression of compile-time type type should be cast before it is interpreted as an edge expression.

Specified by:

getEdgeTypeFor in interface CompiletimeModel

Parameters:

type - the type of the expression

Returns:

the type of the resulting edge expression

getEdgeType

public Type<?> getEdgeType()

Description copied from interface: CompiletimeModel

Specifies the type of standard edges. This method returns the type which is used for the representation of standard edges in this model. This has to be the type of the (possibly unwrapped) values returned by CompiletimeModel.getStandardEdgeFor(int).

Specified by:

getEdgeType in interface CompiletimeModel

Returns:

the type of standard edges

getStandardEdgeFor

public Serializable getStandardEdgeFor(int edgeType)

Description copied from interface: CompiletimeModel

Returns a constant value representing a standard edge. The returned value represents the given standard edge (EdgePattern.ANY_EDGE, EdgePattern.BRANCH_EDGE, EdgePattern.SUCCESSOR_EDGE or EdgePattern.REFINEMENT_EDGE) for this model. It is used as argument to constructor invocations of EdgePattern. Primitive values have to be wrapped as usual.

Specified by:

getStandardEdgeFor in interface CompiletimeModel

Parameters:

edgeType - int-value encoding a standard edge

Returns:

corresponding representation for this model

getWrapProperty

public CompiletimeModel.Property getWrapProperty(Type<?> wrapperType)

Description copied from interface: CompiletimeModel

Returns the unwrapping property of a wrapper type. wrapperType is the type of a wrapper. If there is a property declared in this type which can be used to obtain the wrapped argument, this property is returned, otherwise null.

Specified by:

getWrapProperty in interface CompiletimeModel

Parameters:

wrapperType - the type of a wrapper

Returns:

the unwrapping property for this type

getQueryStateType

public Type<Graph.QState> getQueryStateType()

Description copied from interface: CompiletimeModel

Returns the type of query states to be used for queries for this model.

Specified by:

getQueryStateType in interface CompiletimeModel

Returns:

type of producers

getRuntimeName

public String getRuntimeName()

Description copied from interface: CompiletimeModel

Defines the name of the corresponding RuntimeModel. This name is used during run-time in invocations of RuntimeModelFactory.modelForName(java.lang.String, java.lang.ClassLoader) in order to obtain the RuntimeModel suitable for the code that is compiled within this compile-time model.

Specified by:

getRuntimeName in interface CompiletimeModel

Returns:

the name of the corresponding run-time model
