the class GeneralUtils method createConstructorStatementDefault.

public static Statement createConstructorStatementDefault(FieldNode fNode) {
    final String name = fNode.getName();

Example 12 with ClassNode

use of org.codehaus.groovy.ast.ClassNode in project groovy by apache.

the class GeneralUtils method getterX.

/**
     * This method is similar to {@link #propX(Expression, Expression)} but will make sure that if the property
     * being accessed is defined inside the classnode provided as a parameter, then a getter call is generated
     * instead of a field access.
     * @param annotatedNode the class node where the property node is accessed from
     * @param receiver the object having the property
     * @param pNode the property being accessed
     * @return a method call expression or a property expression
     */
