Constructor Detail

CssNode

public CssNode(CssNode orig,
               String newSelectorText)

Transform constructor - creates a copy but with different selector text.

Parameters:

orig - The node to copy.

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

getComponentNameExpr

@Nullable
public ExprRootNode getComponentNameExpr()

Returns the parsed component name expression, or null if this node has no expression.

getComponentNameText

public String getComponentNameText()

Returns the component name text, or null if this node has no component expression.

getSelectorText

public String getSelectorText()

Returns the selector text from this command.

getRenamedSelectorText

public String getRenamedSelectorText(SoyCssRenamingMap cssRenamingMap)

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.BlockNode 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.StandaloneNode

Overrides:

getParent in class AbstractSoyNode

Returns:

This node's parent.

clone

public CssNode 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.

getCommandName

public String getCommandName()

May be overridden by subclasses to keep consistent with tree modifications.

Specified by:

getCommandName in interface SoyNode.CommandNode

getCommandText

public String getCommandText()

May be overridden by subclasses to keep consistent with tree modifications.

Specified by:

getCommandText in interface SoyNode.CommandNode

getTagString

public String getTagString()

Description copied from interface: SoyNode.CommandNode

Builds a Soy tag string that could be the Soy tag for this node. Note that this may not necessarily be the actual original Soy tag, but a (sort of) canonical equivalent.

Specified by:

getTagString in interface SoyNode.CommandNode

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.

buildTagStringHelper

protected String buildTagStringHelper(boolean isSelfEnding,
                                      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.

Parameters:

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

isImplicitCommandName - Whether the command name is implicit, e.g. a 'print' tag without the explicit 'print'.

Returns:

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

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.

Specified by:

toSourceString in interface Node

Returns:

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