Constructor Details

JLiteralBoolean

public JLiteralBoolean(int line,
 String text)

Constructs an AST node for a boolean literal given its line number and string representation.

Parameters:

line - line in which the literal occurs in the source file.

text - string representation of the literal.

Method Details

toBoolean

public boolean toBoolean()

Returns the literal as a boolean.

Returns:

the literal as a boolean.

analyze

public JExpression analyze(Context context)

Analyzes and returns a JExpression.

Specified by:

analyze in class JExpression

Parameters:

context - context in which names are resolved.

Returns:

the analyzed (and possibly rewritten) AST subtree.

codegen

public void codegen(CLEmitter output)

Performs code generation for this AST.

Specified by:

codegen in class JAST

Parameters:

output - the code emitter.

codegen

public void codegen(CLEmitter output,
 String targetLabel,
 boolean onTrue)

Performs short-circuit code generation for a boolean expression, given the code emitter, a target label, and whether we branch to that label on true or on false.

Overrides:

codegen in class JExpression

Parameters:

output - the code emitter.

targetLabel - the label to which we should branch.

onTrue - do we branch on true?

toJSON

public void toJSON(JSONElement json)

Stores information about this AST in JSON format.

Overrides:

toJSON in class JAST

Parameters:

json - the JSON emitter.
