                           throws CloneNotSupportedException

Overrides:

clone in class NumericLiteral

Throws:

CloneNotSupportedException

copy

public FloatingPointLiteral copy()

Overrides:

copy in class NumericLiteral

fullCopy

public FloatingPointLiteral fullCopy()

Create a deep copy of the AST subtree at this node. The copy is dangling, i.e. has no parent.

Overrides:

fullCopy in class NumericLiteral

Returns:

dangling copy of the subtree at this node

typeCheck

public void typeCheck()

Overrides:

typeCheck in class ASTNode<ASTNode>

eval

public Value eval(Body b)

Overrides:

eval in class Expr

init$Children

public void init$Children()

Initializes the child array to the correct size. Initializes List and Opt nta children.

Overrides:

init$Children in class NumericLiteral

numChildren

protected int numChildren()

Overrides:

numChildren in class NumericLiteral

mayHaveRewrite

public boolean mayHaveRewrite()

Overrides:

mayHaveRewrite in class NumericLiteral

setLITERAL

public void setLITERAL(String value)

Replaces the lexeme LITERAL.

Overrides:

setLITERAL in class NumericLiteral

Parameters:

value - The new value for the lexeme LITERAL.

setLITERAL

public void setLITERAL(Symbol symbol)

JastAdd-internal setter for lexeme LITERAL using the Beaver parser.

Overrides:

setLITERAL in class NumericLiteral

getLITERAL

Utility attribute for literal rewriting. Any of the NumericLiteral subclasses have already been rewritten and/or parsed, and should not be rewritten again.

Overrides:

needsRewrite in class NumericLiteral

Returns:

true if this literal is a "raw", not-yet-parsed NumericLiteral

rewriteTo

public ASTNode rewriteTo()

Overrides:

rewriteTo in class NumericLiteral
