Class FieldAccess<T>

java.lang.Object

com.opencsv.bean.FieldAccess<T>

Type Parameters:

T - The type of the member variable being accessed

public class FieldAccess<T>
extends Object

Encapsulates the logic for accessing member variables of classes.

The logic in opencsv is always:

1. Use an accessor method first, if available, and this always has the form "get"/"set" + member name with initial capital.
2. Use reflection bypassing all access control restrictions.

These are considered separately for reading and writing.

Since:

5.0

hashCode

public int hashCode()

Creates a hash code for this object. This override delegates hash code creation to the field passed in through the constructor and does not includes any of its own state information.

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Determines equality between this object and another. This override delegates equality determination to the field passed in through the constructor and does not includes any of its own state information.

Overrides:

equals in class Object
