Method Detail

getType

public Type getType()

Specified by:

getType in interface HasType

setType

public void setType(Type type,
                    HasType root)

Description copied from interface: HasType

Set the node's type. This may start a chain of type listener notifications

Specified by:

setType in interface HasType

root - The node that initiated the type change chain. When a node receives a type setting command where root == this, we know that we have a type listener circle and can abort. If root == null, the type change is seen as an externally triggered event and subsequent type listeners receive the current node as their root.

resetTypes

public void resetTypes(Type type)

Description copied from interface: HasType

Used to set the type and clear the possible subtypes list for when a type is more precise than the current.

Specified by:

resetTypes in interface HasType

Parameters:

type - the more precise type

registerTypeListener

public void registerTypeListener(HasType.TypeListener listener)

Specified by:

registerTypeListener in interface HasType

unregisterTypeListener

public void unregisterTypeListener(HasType.TypeListener listener)

Specified by:

unregisterTypeListener in interface HasType

getTypeListeners

public java.util.Set<HasType.TypeListener> getTypeListeners()

Specified by:

getTypeListeners in interface HasType

getPossibleSubTypes

public java.util.Set<Type> getPossibleSubTypes()

Specified by:

getPossibleSubTypes in interface HasType

setPossibleSubTypes

public void setPossibleSubTypes(java.util.Set<Type> possibleSubTypes,
                                HasType root)

Description copied from interface: HasType

Set the node's possible subtypes. Listener circle detection works the same way as with HasType.setType(Type, HasType)

Specified by:

setPossibleSubTypes in interface HasType

refreshType

public void refreshType()

Specified by:

refreshType in interface HasType

toString

public java.lang.String toString()

Overrides:

toString in class Declaration

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class Node

hashCode

public int hashCode()

Overrides:

hashCode in class Node
