Constructor Details

JEqualOp

public JEqualOp(int line,
 JExpression lhs,
 JExpression rhs)

Constructs an AST node for an equality expression.

Parameters:

line - line number in which the equality expression occurs in the source file.

lhs - lhs operand.

rhs - rhs operand.

Method Details

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,
 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?
