Constructor Detail

AbstractSoyNode

protected AbstractSoyNode(int id,
                          SourceLocation sourceLocation)

Parameters:

id - The id for this node.

sourceLocation - The node's source location.

AbstractSoyNode

protected AbstractSoyNode(AbstractSoyNode orig)

Copy constructor.

Parameters:

orig - The node to copy.

Method Detail

setId

public void setId(int id)

Description copied from interface: SoyNode

Sets this node's id.

Important: The id should already be set during construction, so this method should only be used during cloning.

Specified by:

setId in interface SoyNode

Parameters:

id - The new id for this node.

getId

public int getId()

Description copied from interface: SoyNode

Returns this node's id.

Specified by:

getId in interface SoyNode

getSourceLocation

public SourceLocation getSourceLocation()

The location in the file from which this node was parsed or derived.

Specified by:

getSourceLocation in interface Node

getParent

public SoyNode.ParentSoyNode<?> getParent()

Description copied from interface: Node

Gets this node's parent.

Specified by:

getParent in interface Node

Specified by:

getParent in interface SoyNode

Overrides:

getParent in class AbstractNode

Returns:

This node's parent.

clone

public abstract SoyNode clone()

Description copied from interface: Node

Copies this node. The clone's parent pointer is set to null.

All clone() overrides should follow this contract:

• only leaf classes (in the class hierarchy) should have non-abstract clone methods
• all leaf classes should be final
• all leaf copy constructors should be private
• all clone methods should look exactly like:

  
      {@literal @}Override public T clone() {
        return new T(this);
      }
   

• all non-leaf copy constructors should be protected

NOTE: this means we do not ultimately delegate to Object.clone(), ever.

TODO(lukes): The usecases for a clone method are few and far between. Making the AST nodes immutable (or at least unmodifiable) would be preferable to maintaining our clone() methods.

Specified by:

clone in interface Node

Specified by:

clone in interface SoyNode

Specified by:

clone in class AbstractNode

Returns:

A clone of this code.

toString

public String toString()

Overrides:

toString in class AbstractNode
