Constructor Detail

MsgSelectNode

public MsgSelectNode(int id,
                     ExprRootNode<?> selectExpr,
                     @Nullable
                     String baseSelectVarName)

Parameters:

id - The id for this node.

selectExpr - The expression for the value to select on.

baseSelectVarName - The base select var name to use (what the translator sees), or null if it should be generated from the select expression.

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

getExpr

public ExprRootNode<?> getExpr()

Returns the expression for the value to select on.

getBaseVarName

public String getBaseVarName()

Returns the base select var name (what the translator sees).

Specified by:

getBaseVarName in interface SoyNode.MsgSubstUnitNode

shouldUseSameVarNameAs

public boolean shouldUseSameVarNameAs(SoyNode.MsgSubstUnitNode other)

Description copied from interface: SoyNode.MsgSubstUnitNode

Returns whether this substitution unit should use the same var name as another substitution unit. (For placeholders, this means the other placeholder is exactly the same as this one, i.e. it appears twice in the same message.)

Specified by:

shouldUseSameVarNameAs in interface SoyNode.MsgSubstUnitNode

Parameters:

other - The other substitution unit to check against.

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

getParent

public SoyNode.MsgBlockNode getParent()

Description copied from interface: Node

Gets this node's parent.

Specified by:

getParent in interface Node

Specified by:

getParent in interface SoyNode

Specified by:

getParent in interface SoyNode.MsgSubstUnitNode

Specified by:

getParent in interface SoyNode.StandaloneNode

Overrides:

getParent in class AbstractSoyNode

Returns:

This node's parent.

clone

public MsgSelectNode 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.
