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

getCaseValue

public String getCaseValue()

Returns the case value.

clone

public MsgSelectCaseNode 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.

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(N 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

Parameters:

child - The child to add.

addChild

public void addChild(int index,
                     N child)

Description copied from interface: ParentNode

Adds the given child at the given index (shifting existing children if necessary).

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)

Description copied from interface: ParentNode

Removes the given child.

Specified by:

Specified by:

replaceChild in interface ParentNode<N extends SoyNode>

Parameters:

index - The index of the child to replace.

Returns:

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

buildTagStringHelper

protected String buildTagStringHelper(boolean isSelfEnding)

Helper to build the source tag string (usually for testing/debugging). Handles most cases, including (a) with or without tag text, (b) self-ending tags, or (c) tags whose text contains a brace character.

Parameters:

isSelfEnding - Whether the tag is self-ending, i.e. { ... /}.

Returns:

The source tag string, possibly with some differences in spacing.

                                      boolean isImplicitCommandName)

Helper to build the source tag string (usually for testing/debugging). Handles all cases, including (a) with or without tag text, (b) self-ending tags, (c) tags whose text contains a brace character, or (d) implicit 'print' tags.
