Method Detail

isId

public boolean isId()

Affirms if this attribute is an id attribute.

Specified by:

isId in interface SingularAttribute<X,T>

isVersion

public boolean isVersion()

Affirms if this attribute represents a version attribute.

Specified by:

isVersion in interface SingularAttribute<X,T>

isOptional

public boolean isOptional()

Affirms if this attribute can be null.

Specified by:

isOptional in interface SingularAttribute<X,T>

getBindableType

public final Bindable.BindableType getBindableType()

Categorizes bindable type represented by this attribute.

Specified by:

getBindableType in interface Bindable<T>

getBindableJavaType

public final Class<T> getBindableJavaType()
