Example 1 with ClassGeneratorException

use of org.codehaus.groovy.classgen.ClassGeneratorException in project groovy by apache.

the class OperandStack method pushConstant.

/**
     * load the constant on the operand stack. 
     */
public void pushConstant(ConstantExpression expression) {
    MethodVisitor mv = controller.getMethodVisitor();
    Object value = expression.getValue();
    ClassNode origType = expression.getType().redirect();
    ClassNode type = ClassHelper.getUnwrapper(origType);
    boolean boxing = origType != type;
    boolean asPrimitive = boxing || ClassHelper.isPrimitiveType(type);
    if (value == null) {
        mv.visitInsn(ACONST_NULL);
