Methods

Modifier and Type	Method and Description
java.lang.Object	create(int tokenType, java.lang.String text) Create a new node derived from a token, with a new token type.
java.lang.Object	create(org.antlr.runtime.Token token) Create a tree node from Token object; for CommonTree type trees, then the token just becomes the payload.

Method Detail

create

public java.lang.Object create(org.antlr.runtime.Token token)

Description copied from interface: org.antlr.runtime.tree.TreeAdaptor

Create a tree node from Token object; for CommonTree type trees, then the token just becomes the payload. This is the most common create call. Override if you want another kind of node to be built.

Specified by:

create in interface org.antlr.runtime.tree.TreeAdaptor

Overrides:

create in class org.antlr.runtime.tree.CommonTreeAdaptor

create

public java.lang.Object create(int tokenType,
                      java.lang.String text)

Description copied from interface: org.antlr.runtime.tree.TreeAdaptor

Create a new node derived from a token, with a new token type. This is invoked from an imaginary node ref on right side of a rewrite rule as IMAG["IMAG"]. This should invoke createToken(int,String).

Specified by:

create in interface org.antlr.runtime.tree.TreeAdaptor

Overrides:

create in class org.antlr.runtime.tree.BaseTreeAdaptor

dupNode

public java.lang.Object dupNode(java.lang.Object t)

Description copied from class: org.antlr.runtime.tree.CommonTreeAdaptor

Duplicate a node. This is part of the factory; override if you want another kind of node to be built. I could use reflection to prevent having to override this but reflection is slow.

Specified by:

dupNode in interface org.antlr.runtime.tree.TreeAdaptor

Overrides:

dupNode in class org.antlr.runtime.tree.CommonTreeAdaptor

errorNode

public java.lang.Object errorNode(org.antlr.runtime.TokenStream input,
                         org.antlr.runtime.Token start,
                         org.antlr.runtime.Token stop,
                         org.antlr.runtime.RecognitionException e)

Description copied from class: org.antlr.runtime.tree.BaseTreeAdaptor

create tree node that holds the start and stop tokens associated with an error. If you specify your own kind of tree nodes, you will likely have to override this method. CommonTree returns Token.INVALID_TOKEN_TYPE if no token payload but you might have to set token type for diff node type. You don't have to subclass CommonErrorNode; you will likely need to subclass your own tree node class to avoid class cast exception.

Specified by:

errorNode in interface org.antlr.runtime.tree.TreeAdaptor

Overrides:

errorNode in class org.antlr.runtime.tree.BaseTreeAdaptor
