Class AbstractJavaMember

java.lang.Object

org.apache.jdo.impl.model.java.AbstractJavaMember

All Implemented Interfaces:

JavaElement, JavaMember

Direct Known Subclasses:

BaseReflectionJavaField, JavaPropertyImpl, ReflectionJavaMethod

public abstract class AbstractJavaMember
extends java.lang.Object
implements JavaMember

Abstract super class for JavaMember implementations. It provides getters for the name and declaringClass properties which are initialized in the constructor.

A non-abstract subclass must implement methods getModifiers() and getType().

Since:

JDO 2.0

Constructor Detail

AbstractJavaMember

public AbstractJavaMember(java.lang.String name,
                  JavaType declaringClass)

Constructor setting the name and declaringClass property.

Parameters:

name - field name

declaringClass - the JavaType of the class or interface that declares this JavaMember.

Method Detail

getName

public java.lang.String getName()

Returns the name of the field.

Specified by:

getName in interface JavaMember

Returns:

field name

getDeclaringClass

public JavaType getDeclaringClass()

Returns the JavaType instance representing the class or interface that declares the field represented by this JavaMember instance.

Specified by:

getDeclaringClass in interface JavaMember

Returns:

the JavaType instance of the declaring class.

getModifiers

public abstract int getModifiers()

Returns the Java language modifiers for the member represented by this JavaMember, as an integer. The java.lang.reflect.Modifier class should be used to decode the modifiers.

Specified by:

getModifiers in interface JavaMember

Returns:

the Java language modifiers for this JavaMember

Modifier

getType

public abstract JavaType getType()

Returns the JavaType representation of the type of the memeber.

Specified by:

getType in interface JavaMember

Returns:

type of the member

getComponentType

public JavaType getComponentType()

Returns the JavaType representation of the component type of the type of the property, if the property type is an array or collection. The method returns null, if the property type is not an array or collection.

Specified by:

getComponentType in interface JavaMember

Returns:

the component type of the property type in case of an array or collection.

equals

public boolean equals(java.lang.Object obj)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the reference object with which to compare.

This implementation matches the declaring class and the name of the specified object to the declaring class and the name of this JavaMember.

Returns:

true if this object is the same as the obj argument; false otherwise.

hashCode

public int hashCode()

Returns a hash code value for the object.

This is computed as the exclusive-or of the hashcodes for the underlying field's declaring class name and its name.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for this object.

toString

public java.lang.String toString()

Returns a string representation of the object.

Overrides:

toString in class java.lang.Object

Returns:

a string representation of the object.
