persistence.antlr.DiagnosticCodeGenerator
| DiagnosticCodeGenerator | | public class DiagnosticCodeGenerator extends CodeGenerator (Code) | | Generate MyParser.txt, MyLexer.txt and MyParserTokenTypes.txt
|
| Constructor Summary | |
| public | DiagnosticCodeGenerator()
Create a Diagnostic code-generator using the given Grammar
The caller must still call setTool, setBehavior, and setAnalyzer
before generating code. |
| doingLexRules | | protected boolean doingLexRules(Code) | | true during lexer generation, false during parser generation
|
| syntacticPredLevel | | protected int syntacticPredLevel(Code) | | non-zero if inside syntactic predicate generation
|
| DiagnosticCodeGenerator | | public DiagnosticCodeGenerator()(Code) | | Create a Diagnostic code-generator using the given Grammar
The caller must still call setTool, setBehavior, and setAnalyzer
before generating code.
|
| gen | | public void gen()(Code) | | Generate the parser, lexer, and token types documentation
|
| gen | | public void gen(ActionElement action)(Code) | | Generate code for the given grammar element.
Parameters:
blk - The {...} action to generate |
| gen | | public void gen(AlternativeBlock blk)(Code) | | Generate code for the given grammar element.
Parameters:
blk - The "x|y|z|..." block to generate |
| gen | | public void gen(BlockEndElement end)(Code) | | Generate code for the given grammar element.
Parameters:
blk - The block-end element to generate. Block-endelements are synthesized by the grammar parser to representthe end of a block. |
| gen | | public void gen(CharLiteralElement atom)(Code) | | Generate code for the given grammar element.
Parameters:
blk - The character literal reference to generate |
| gen | | public void gen(CharRangeElement r)(Code) | | Generate code for the given grammar element.
Parameters:
blk - The character-range reference to generate |
| gen | | public void gen(OneOrMoreBlock blk)(Code) | | Generate code for the given grammar element.
Parameters:
blk - The (...)+ block to generate |
| gen | | public void gen(RuleRefElement rr)(Code) | | Generate code for the given grammar element.
Parameters:
blk - The rule-reference to generate |
| gen | | public void gen(StringLiteralElement atom)(Code) | | Generate code for the given grammar element.
Parameters:
blk - The string-literal reference to generate |
| gen | | public void gen(TokenRangeElement r)(Code) | | Generate code for the given grammar element.
Parameters:
blk - The token-range reference to generate |
| gen | | public void gen(TokenRefElement atom)(Code) | | Generate code for the given grammar element.
Parameters:
blk - The token-reference to generate |
| gen | | public void gen(ZeroOrMoreBlock blk)(Code) | | Generate code for the given grammar element.
Parameters:
blk - The (...)* block to generate |
| genBlockPreamble | | protected void genBlockPreamble(AlternativeBlock blk)(Code) | | Generate the header for a block, which may be a RuleBlock or a
plain AlternativeBLock. This generates any variable declarations,
init-actions, and syntactic-predicate-testing variables.
|
| genCommonBlock | | public void genCommonBlock(AlternativeBlock blk)(Code) | | Generate common code for a block of alternatives; return a postscript
that needs to be generated at the end of the block. Other routines
may append else-clauses and such for error checking before the postfix
is generated.
|
| genFollowSetForRuleBlock | | public void genFollowSetForRuleBlock(RuleBlock blk)(Code) | | Generate a textual representation of the follow set
for a block.
Parameters:
blk - The rule block of interest |
| genHeader | | protected void genHeader()(Code) | | Generate a header that is common to all TXT files
|
| genLookaheadSetForAlt | | protected void genLookaheadSetForAlt(Alternative alt)(Code) | | Generate the lookahead set for an alternate.
|
| genLookaheadSetForBlock | | public void genLookaheadSetForBlock(AlternativeBlock blk)(Code) | | Generate a textual representation of the lookahead set
for a block.
Parameters:
blk - The block of interest |
| genNextToken | | public void genNextToken()(Code) | | Generate the nextToken rule.
nextToken is a synthetic lexer rule that is the implicit OR of all
user-defined lexer rules.
|
| genRule | | public void genRule(RuleSymbol s)(Code) | | Generate code for a named rule block
Parameters:
s - The RuleSymbol describing the rule to generate |
| genSynPred | | protected void genSynPred(SynPredBlock blk)(Code) | | Generate the syntactic predicate. This basically generates
the alternative block, buts tracks if we are inside a synPred
Parameters:
blk - The syntactic predicate block |
| getASTCreateString | | public String getASTCreateString(Vector v)(Code) | | Get a string for an expression to generate creation of an AST subtree.
Parameters:
v - A Vector of String, where each element is an expression in the target language yielding an AST node. |
| getASTCreateString | | public String getASTCreateString(GrammarAtom atom, String str)(Code) | | Get a string for an expression to generate creating of an AST node
Parameters:
str - The arguments to the AST constructor |
| mapTreeId | | public String mapTreeId(String id, ActionTransInfo tInfo)(Code) | | Map an identifier to it's corresponding tree-node variable.
This is context-sensitive, depending on the rule and alternative
being generated
Parameters:
id - The identifier name to map
Parameters:
forInput - true if the input tree node variable is to be returned, otherwise the output variable is returned. |
| printSet | | public void printSet(int depth, int k, Lookahead lookahead)(Code) | | Format a lookahead or follow set.
Parameters:
depth - The depth of the entire lookahead/follow
Parameters:
k - The lookahead level to print
Parameters:
lookahead - The lookahead/follow set to print |
