Constructor Detail

SwitchCaseNode

public SwitchCaseNode(int id,
                      SourceLocation location,
                      com.google.common.collect.ImmutableList<ExprNode> exprList)

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

getCommandText

public String getCommandText()

Description copied from interface: SoyNode.CommandNode

Returns the command text (may be the empty string).

Specified by:

getCommandText in interface SoyNode.CommandNode

getExprList

public com.google.common.collect.ImmutableList<ExprRootNode> getExprList()

Description copied from interface: SoyNode.ExprHolderNode

Returns the list of expressions in this node.

Specified by:

getExprList in interface SoyNode.ExprHolderNode

copy

public SwitchCaseNode copy(CopyState copyState)

Description copied from interface: SoyNode

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

All copy() 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 copy(CopyState copyState) {
     return new T(this, copyState);
   }
   

• all non-leaf copy constructors should be protected

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

Don't clone nodes unless you know what you're doing. The Soy AST is not actually a tree (it contains back edges from variables to their definitions), and naively copying nodes can result in pointers into stale ASTs

The copied nodes will have the same ids as the original nodes. If you need to copy a subtree with new ids assigned to the copied nodes, use SoyTreeUtils.cloneWithNewIds(T, com.google.template.soy.base.internal.IdGenerator).

Specified by:

copy in interface Node

Specified by:

copy in interface SoyNode

Returns:

A clone of this code.

numChildren

public int numChildren()

Description copied from interface: ParentNode

Gets the number of children.

Specified by:

numChildren in interface ParentNode<N extends SoyNode>

Returns:

The number of children.

getChild

public N getChild(int index)

Description copied from interface: ParentNode

Gets the child at the given index.

Specified by:

getChild in interface ParentNode<N extends SoyNode>

Parameters:

index - The index of the child to get.

Returns:

The child at the given index.

getChildIndex

public int getChildIndex(Node child)

Description copied from interface: ParentNode

Finds the index of the given child.

Specified by:

getChildIndex in interface ParentNode<N extends SoyNode>

Parameters:

child - The child to find the index of.

Returns:

The index of the given child, or -1 if the given child is not a child of this node.

getChildren

public List<N> getChildren()

Description copied from interface: ParentNode

Gets the list of children.

Note: The returned list may not be a copy. Please do not modify the list directly. Instead, use the other methods in this class that are intended for modifying children. Also, if you're iterating over the children list as you're modifying it, then you should first make a copy of the children list to iterate over, in order to avoid ConcurrentModificationException.

Specified by:

getChildren in interface ParentNode<N extends SoyNode>

Returns:

The list of children.

addChild

public void addChild(N child)

Description copied from interface: ParentNode

Adds the given child.

addChild in interface ParentNode<N extends SoyNode>

Parameters:

child - The child to add.

addChild

public void addChild(int index,
                     N child)

Specified by:

addChild in interface ParentNode<N extends SoyNode>

Parameters:

index - The index to add the child at.

child - The child to add.

removeChild

public void removeChild(int index)

Description copied from interface: ParentNode

Removes the child at the given index.

Specified by:

removeChild in interface ParentNode<N extends SoyNode>

Parameters:

index - The index of the child to remove.

removeChild

public void removeChild(N child)
