public static final SoyError SELF_ENDING_WITHOUT_VALUE

Method Detail

getKind

public SoyNode.Kind getKind()

Description copied from interface: SoyNode

Returns this node's kind (corresponding to this node's specific type).

Specified by:

getKind in interface SoyNode

getVarName

public final String getVarName()

Return The local variable name (without preceding '$').

Specified by:

getVarName in interface SoyNode.LocalVarNode

getValueExpr

public ExprRootNode<?> getValueExpr()

Returns the value expression that the variable is set to.

getAllExprUnions

public List<ExprUnion> getAllExprUnions()

Description copied from interface: SoyNode.ExprHolderNode

Returns the list of expressions in this node.

Specified by:

getAllExprUnions in interface SoyNode.ExprHolderNode

clone

public LetValueNode 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 AbstractSoyNode

Returns:

A clone of this code.
