Example 10 with AbstractMethodDeclaration

use of org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration in project lombok by rzwitserloot.

the class HandleBuilder method makeSimpleSetterMethodForBuilder.

private void makeSimpleSetterMethodForBuilder(EclipseNode builderType, EclipseNode fieldNode, EclipseNode sourceNode, boolean fluent, boolean chain) {
    TypeDeclaration td = (TypeDeclaration) builderType.get();
    AbstractMethodDeclaration[] existing = td.methods;
    if (existing == null)
        existing = EMPTY;
    int len = existing.length;
    FieldDeclaration fd = (FieldDeclaration) fieldNode.get();
    char[] name = fd.name;
    for (int i = 0; i < len; i++) {
        if (!(existing[i] instanceof MethodDeclaration))
            continue;
        char[] existingName = existing[i].selector;
        if (Arrays.equals(name, existingName) && !isTolerate(fieldNode, existing[i]))
            return;
    }
    String setterName = fluent ? fieldNode.getName() : HandlerUtil.buildAccessorName("set", fieldNode.getName());
    MethodDeclaration setter = HandleSetter.createSetter(td, fieldNode, setterName, chain, ClassFileConstants.AccPublic, sourceNode, Collections.<Annotation>emptyList(), Collections.<Annotation>emptyList());
    injectMethod(builderType, setter);
