public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

getModifiers

public int getModifiers()

Description copied from interface: ResolvedJavaField

Returns the Java Virtual Machine modifiers for this element. Note that this can differ from standard Java Reflection modifiers. For example at the JVM level, classes ( ResolvedJavaType) can not be private or protected.

Only the field flags specified in the JVM specification will be included in the returned mask.

Specified by:

getModifiers in interface ModifiersProvider

Specified by:

getModifiers in interface ResolvedJavaField

isInternal

public boolean isInternal()

Description copied from interface: ResolvedJavaField

Determines if this field was injected by the VM. Such a field, for example, is not derived from a class file.

Specified by:

isInternal in interface ResolvedJavaField

isInObject

public boolean isInObject(Object object)

Determines if a given object contains this field.

Specified by:

isInObject in interface HotSpotResolvedJavaField

Returns:

true iff this is a non-static field and its declaring class is assignable from object's class

getDeclaringClass

public HotSpotResolvedObjectTypeImpl getDeclaringClass()

Description copied from interface: ResolvedJavaField

Returns the ResolvedJavaType object representing the class or interface that declares this field.

Specified by:

getDeclaringClass in interface JavaField

Specified by:

getDeclaringClass in interface ResolvedJavaField

getName

public String getName()

Description copied from interface: JavaField

Returns the name of this field.

Specified by:

getName in interface JavaField

getType

public JavaType getType()

Description copied from interface: JavaField

Returns a JavaType object that identifies the declared type for this field.

Specified by:

getType in interface JavaField

offset

public int offset()

Specified by:

offset in interface HotSpotResolvedJavaField

toString

public String toString()

Overrides:

toString in class Object

isSynthetic

public boolean isSynthetic()

Description copied from interface: ResolvedJavaField

Determines if this field is a synthetic field as defined by the Java Language Specification.

Specified by:

isSynthetic in interface ResolvedJavaField

isStable

public boolean isStable()

Checks if this field has the Stable annotation.

Specified by:

isStable in interface HotSpotResolvedJavaField

Returns:

true if field has Stable annotation, false otherwise

getAnnotation

public <T extends Annotation> T getAnnotation(Class<T> annotationClass)

Description copied from interface: ResolvedJavaField

Returns the annotation for the specified type of this field, if such an annotation is present.

Specified by:

getAnnotation in interface ResolvedJavaField

Parameters:

annotationClass - the Class object corresponding to the annotation type

Returns:

this element's annotation for the specified annotation type if present on this field, else null

toJava

private Field toJava()

isArray

private boolean isArray()

isImplicitStableField

private boolean isImplicitStableField()
