KeywordLiteral
public KeywordLiteral(int pos,
int len,
int nodeType)
- Constructs a new KeywordLiteral
- Parameters:
nodeType
- the token type
setType
public KeywordLiteral setType(int nodeType)
- Sets node token type
- Overrides:
setType
in class Node
- Throws:
java.lang.IllegalArgumentException
- if nodeType
is unsupported
isBooleanLiteral
public boolean isBooleanLiteral()
- Returns true if the token type is
Token.TRUE
or
Token.FALSE
.
toSource
public java.lang.String toSource(int depth)
- Description copied from class:
AstNode
- Emits source code for this node. Callee is responsible for calling this
function recursively on children, incrementing indent as appropriate.
Note: if the parser was in error-recovery mode, some AST nodes may have
null
children that are expected to be non-null
when no errors are present. In this situation, the behavior of the
toSource
method is undefined: toSource
implementations may assume that the AST node is error-free, since it is
intended to be invoked only at runtime after a successful parse.
- Specified by:
toSource
in class AstNode
- Parameters:
depth
- the current recursion depth, typically beginning at 0
when called on the root node.
visit
public void visit(NodeVisitor v)
- Visits this node. There are no children to visit.
- Specified by:
visit
in class AstNode
- Parameters:
v
- the object to call with this node and its children
