appendedBlock

public void appendedBlock(AST callee)
An appended block follows any expression. If the expression is not a method call, it is given an empty argument list.


argList

public void argList()


argument

public byte argument()
A single argument in (...) or [...]. Corresponds to to a method or closure parameter. May be labeled. May be modified by the spread operator '*' ('*:' for keywords).


argumentLabel

public void argumentLabel()


argumentLabelStart

public void argumentLabelStart()
For lookahead only. Fast approximate parse of an argumentLabel followed by a colon.


assignmentExpression

public void assignmentExpression(int lc_stmt)


assignmentLessExpression

public void assignmentLessExpression()


balancedBrackets

public void balancedBrackets()
Fast lookahead across balanced brackets of all sorts.


balancedTokens

public void balancedTokens()


blockBody

public void blockBody(int prevToken)
A block body is a parade of zero or more statements or expressions.


branchStatement

public void branchStatement()
In Groovy, return, break, continue, throw, and assert can be used in a parenthesized expression context. Example: println (x || (return)); println assert x, "won't print a false value!" If an optional expression is missing, its value is void (this coerces to null when a value is required).


buildTokenTypeASTClassMap

void buildTokenTypeASTClassMap()


builtInType

public void builtInType()


builtInTypeArraySpec

public void builtInTypeArraySpec(boolean addImagNode)


builtInTypeSpec

public void builtInTypeSpec(boolean addImagNode)


caseSList

public void caseSList()


casesGroup

public void casesGroup()


checkSuspiciousExpressionStatement

public void checkSuspiciousExpressionStatement(int prevToken)
If two statements are separated by newline (not SEMI), the second had better not look like the latter half of an expression. If it does, issue a warning.

Also, if the expression starts with a closure, it needs to have an explicit parameter list, in order to avoid the appearance of a compound statement. This is a hard error.

These rules are different from Java's "dumb expression" restriction. Unlike Java, Groovy blocks can end with arbitrary (even dumb) expressions, as a consequence of optional 'return' and 'continue' tokens.

To make the programmer's intention clear, a leading closure must have an explicit parameter list, and must not follow a previous statement separated only by newlines.


classBlock

public void classBlock()


classDefinition

public void classDefinition(AST modifiers)


classField

public void classField()


classOrInterfaceType

public void classOrInterfaceType(boolean addImagNode)


classTypeSpec

public void classTypeSpec(boolean addImagNode)


cloneToken

public Token cloneToken(Token t)
Clones the token


closableBlock

public void closableBlock()
A block which is known to be a closure, even if it has no apparent arguments. A block inside an expression or after a method call is always assumed to be a closure. Only labeled, unparameterized blocks which occur directly as substatements are kept open.


closableBlockConstructorExpression

public void closableBlockConstructorExpression()


closableBlockParam

public void closableBlockParam()


closableBlockParamsOpt

public void closableBlockParamsOpt(boolean addImplicit)
Closure parameters are exactly like method parameters, except that they are not enclosed in parentheses, but rather are prepended to the front of a block, just after the brace. They are separated from the closure body by a CLOSABLE_BLOCK_OP token '->'.


closableBlockParamsStart

public void closableBlockParamsStart()
Lookahead to check whether a block begins with explicit closure arguments.


closureList

public void closureList()


commandArgument

public void commandArgument()


commandArguments

public void commandArguments(AST head)
A member name (x.y) or element name (x[y]) can serve as a command name, which may be followed by a list of arguments. Unlike parenthesized arguments, these must be plain expressions, without labels or spread operators.


compatibleBodyStatement

public void compatibleBodyStatement()
In Java, "if", "while", and "for" statements can take random, non-braced statements as their bodies. Support this practice, even though it isn't very Groovy.


compilationUnit

public void compilationUnit()


compoundStatement

public void compoundStatement()


conditionalExpression

public void conditionalExpression(int lc_stmt)


constant

public void constant()
Numeric, string, regexp, boolean, or null constant.


constantNumber

public void constantNumber()
Numeric constant.


constructorBody

public void constructorBody()


constructorDefinition

public void constructorDefinition(AST mods)
I've split out constructors separately; we could maybe integrate back into variableDefinitions later on if we maybe simplified 'def' to be a type declaration?


constructorStart

public void constructorStart()
Used to look ahead for a constructor


controlExpressionList

public void controlExpressionList()


create

public AST create(int type, String txt, Token first, Token last)
Create an AST node with the token type and text passed in, but with the same background information as another supplied Token (e.g. line numbers). To be used in place of antlr tree construction syntax, i.e. #[TOKEN,"text"] becomes create(TOKEN,"text",anotherToken) todo - change antlr.ASTFactory to do this instead...

public AST create(int type, String txt, AST first, Token last)


declaration

public void declaration()
A declaration is the creation of a reference or primitive-type variable, or (if arguments are present) of a method. Generically, this is called a 'variable' definition, even in the case of a class field or method. It may start with the modifiers and/or a declaration keyword "def". It may also start with the modifiers and a capitalized type name.

AST effect: Create a separate Type/Var tree for each var in the var list. Must be guarded, as in (declarationStart) => declaration.


declarationStart

public void declarationStart()


declaratorBrackets

public void declaratorBrackets(AST typ)
After some type names, where zero or more empty bracket pairs are allowed. We use ARRAY_DECLARATOR to represent this. TODO: Is there some more Groovy way to view this in terms of the indexed property syntax?


dynamicMemberName

public void dynamicMemberName()
If a dot is followed by a parenthesized or quoted expression, the member is computed dynamically, and the member selection is done only at runtime. This forces a statically unchecked member access.


enumBlock

public void enumBlock()


enumConstant

public void enumConstant()


enumConstantBlock

public void enumConstantBlock()


enumConstantField

public void enumConstantField()


enumConstants

public void enumConstants()
Comma-separated list of one or more enum constant definitions.


enumConstantsStart

public void enumConstantsStart()
Guard for enumConstants.


enumDefinition

public void enumDefinition(AST modifiers)


equalityExpression

public void equalityExpression(int lc_stmt)


exclusiveOrExpression

public void exclusiveOrExpression(int lc_stmt)


explicitConstructorInvocation

public void explicitConstructorInvocation()
Catch obvious constructor calls, but not the expr.super(...) calls


expression

public void expression(int lc_stmt)


expressionStatement

public void expressionStatement(int prevToken)
An expression statement can be any general expression.

An expression statement can also be a command, which is a simple method call in which the outermost parentheses are omitted.

Certain "suspicious" looking forms are flagged for the user to disambiguate.

implementsClause

public void implementsClause()


implicitParameters

public void implicitParameters()
A block known to be a closure, but which omits its arguments, is given this placeholder. A subsequent pass is responsible for deciding if there is an implicit 'it' parameter, or if the parameter list should be empty.


importStatement

public void importStatement()


inclusiveOrExpression

public void inclusiveOrExpression(int lc_stmt)


indexPropertyArgs

public void indexPropertyArgs(AST indexee)
An expression may be followed by [...]. Unlike Java, these brackets may contain a general argument list, which is passed to the array element operator, which can make of it what it wants. The brackets may also be empty, as in T[]. This is how Groovy names array types.

Returned AST is [INDEX_OP, indexee, ELIST].


interfaceBlock

public void interfaceBlock()


interfaceDefinition

public void interfaceDefinition(AST modifiers)


interfaceExtends

public void interfaceExtends()


interfaceField

public void interfaceField()


isConstructorIdent

boolean isConstructorIdent(Token x)


isUpperCase

boolean isUpperCase(Token x)


keywordPropertyNames

public void keywordPropertyNames()
Allowed keywords after dot (as a member name) and before colon (as a label). TODO: What's the rationale for these?


listOrMapConstructorExpression

public void listOrMapConstructorExpression()
A list constructor is a argument list enclosed in square brackets, without labels. Any argument can be decorated with a spread operator (*x), but not a label (a:x). Examples: [], [1], [1,2], [1,*l1,2], [*l1,*l2]. (The l1, l2 must be a sequence or null.)

A map constructor is an argument list enclosed in square brackets, with labels everywhere, except on spread arguments, which stand for whole maps spliced in. A colon alone between the brackets also forces the expression to be an empty map constructor. Examples: [:], [a:1], [a:1,b:2], [a:1,*:m1,b:2], [*:m1,*:m2] (The m1, m2 must be a map or null.) Values associated with identical keys overwrite from left to right: [a:1,a:2] === [a:2]

Some malformed constructor expressions are not detected in the parser, but in a post-pass. Bad examples: [1,b:2], [a:1,2], [:1]. (Note that method call arguments, by contrast, can be a mix of keyworded and non-keyworded arguments.)
