Example 71 with BlockStatement

use of org.codehaus.groovy.ast.stmt.BlockStatement in project groovy-core by groovy.

the class BindableASTTransformation method wrapSetterMethod.

     * Wrap an existing setter.
     */
private void wrapSetterMethod(ClassNode classNode, String propertyName) {
    String getterName = "get" + MetaClassHelper.capitalize(propertyName);
    MethodNode setter = classNode.getSetterMethod("set" + MetaClassHelper.capitalize(propertyName));

        // Get the existing code block
        Statement code = setter.getCode();
        Expression oldValue = varX("$oldValue");
        Expression newValue = varX("$newValue");
        BlockStatement block = new BlockStatement();
        // create a local variable to hold the old value from the getter
        block.addStatement(declS(oldValue, callThisX(getterName)));
        // call the existing block, which will presumably set the value properly
        block.addStatement(code);
        // get the new value to emit in the event
        block.addStatement(declS(newValue, callThisX(getterName)));
        // add the firePropertyChange method call
        block.addStatement(stmt(callThisX("firePropertyChange", args(constX(propertyName), oldValue, newValue))));
