Constructor Detail

MapLiteralNode

public MapLiteralNode(List<ExprNode> alternatingKeysAndValues,
                      SourceLocation sourceLocation)

Parameters:

alternatingKeysAndValues - The keys and values (alternating) in this map.

Method Detail

getKind

public ExprNode.Kind getKind()

Description copied from interface: ExprNode

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

Returns:

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

toSourceString

public String toSourceString()

Description copied from interface: Node

Builds a Soy source string that could be the source for this node. Note that this is not the actual original source string, but a (sort of) canonical equivalent. Note: Some nodes do not have a direct mapping to Soy source (such as nodes created during some optimization passes). Thus this method may not always be supported.

Returns:

A Soy string that could be the source for this node.

clone

public MapLiteralNode 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 ExprNode

Specified by:

Returns:

A clone of this code.
