Examples with FieldNode org.apache.xbean.asm5.tree.FieldNode used on opensource projects

Example 1 with FieldNode

use of org.apache.xbean.asm5.tree.FieldNode in project apex-malhar by apache.

the class BeanClassGenerator method addPrivateField.

/**
 * Add private field to the class
 * @param classNode ClassNode which needs to be populated with private field.
 * @param fieldName Name of the field
 * @param fieldJavaType Java ASM type of the field
 */
@SuppressWarnings("unchecked")

    FieldNode fieldNode = new FieldNode(Opcodes.ACC_PRIVATE, fieldName, fieldJavaType, null, null);
    classNode.fields.add(fieldNode);
}

Example 2 with FieldNode

use of org.apache.xbean.asm5.tree.FieldNode in project apex-core by apache.

the class CompactUtil method updateCompactClassPortInfo.

public static void updateCompactClassPortInfo(ClassNode cn, CompactClassNode ccn) {
    List<FieldNode> fields = ASMUtil.getPorts(cn);
    List<CompactFieldNode> ports = new LinkedList<>();
    for (FieldNode fn : fields) {
        ports.add(compactFieldNode(fn));
    }
    ccn.setPorts(ports);
}

Example 3 with FieldNode

use of org.apache.xbean.asm5.tree.FieldNode in project apex-malhar by apache.

the class BeanClassGenerator method addDateFields.

/**
 * Date field is explicitly handled and provided with 3 variants of types of same data.
 * 1. java.util.Date format
 * 2. long - Epoc time in ms
 * 3. int - Epoc time in sec rounded to date
 *
 * This is purposefully done because SQL operations on Date etc happens on long or int based on whether its a SQL DATE
 * field OR SQL TIMESTAMP field. Hence to cater to that 2 more variant of the same data is added to the POJO.
