Constructor Detail

JLessEqualOp

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

Construct an AST node for a less-than-or-equal-to expression given its line number, and the lhs and rhs operands.

Parameters:

line - line in which the less-than-or-equal-to expression occurs in the source file.

lhs - lhs operand.

rhs - rhs operand.

Method Detail

codegen

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

Branching code generation for <= operation.

Overrides:

codegen in class JExpression

Parameters:

output - the code emitter (basically an abstraction for producing the .class file).

targetLabel - target for generated branch instruction.

onTrue - should we branch on true?
