Method Detail

isId

public boolean isId()

Affirms if this attribute is an id attribute.

Specified by:

isId in interface javax.persistence.metamodel.SingularAttribute<X,T>

isVersion

public boolean isVersion()

Affirms if this attribute represents a version attribute.

Specified by:

isVersion in interface javax.persistence.metamodel.SingularAttribute<X,T>

isOptional

public boolean isOptional()

Affirms if this attribute can be null.

Specified by:

isOptional in interface javax.persistence.metamodel.SingularAttribute<X,T>

getBindableType

public final javax.persistence.metamodel.Bindable.BindableType getBindableType()

Categorizes bindable type represented by this attribute.

Specified by:

getBindableType in interface javax.persistence.metamodel.Bindable<T>

getBindableJavaType

public final Class<T> getBindableJavaType()
