Detailed DescriptionThis is the standard tree adaptor used by the C runtime unless the grammar source file says to use anything different. It embeds a BASE_TREE to which it adds its own implementation of anything that the base tree is not good for, plus a number of methods that any other adaptor type needs to implement too.

ANTLR3_API pANTLR3_BASE_TREE_ADAPTOR ANTLR3_TREE_ADAPTORNew (pANTLR3_STRING_FACTORY strFactory)Create a new tree adaptor. Note that despite the fact that this is creating a new COMMON_TREE adaptor, we return the address of the BASE_TREE interface, as should any other adaptor that wishes to be used as the tree element of a tree parse/build. It needs to be given the address of a valid string factory as we do not know what the originating input stream encoding type was. This way we can rely on just using the original input stream's string factory or one of the correct type which the user supplies us.

static pANTLR3_COMMON_TOKEN createToken (pANTLR3_BASE_TREE_ADAPTOR adaptor, ANTLR3_UINT32 tokenType, pANTLR3_UINT8 text) [static]Tell me how to create a token for use with imaginary token nodes. For example, there is probably no input symbol associated with imaginary token DECL, but you need to create it as a payload or whatever for the DECL node as in ^(DECL type ID). If you care what the token payload objects' type is, you should override this method and any other createToken variant.

static pANTLR3_COMMON_TOKEN createTokenFromToken (pANTLR3_BASE_TREE_ADAPTOR adaptor, pANTLR3_COMMON_TOKEN fromToken) [static]Tell me how to create a token for use with imaginary token nodes. For example, there is probably no input symbol associated with imaginary token DECL, but you need to create it as a payload or whatever for the DECL node as in ^(DECL type ID). This is a variant of createToken where the new token is derived from an actual real input token. Typically this is for converting '{' tokens to BLOCK etc... You'll see r : lc='{' ID+ '}' -> ^(BLOCK[$lc] ID+) ; If you care what the token payload objects' type is, you should override this method and any other createToken variant. NB: this being C it is not so easy to extend the types of creaeteToken. We will have to see if anyone needs to do this and add any variants to this interface.
