getType

public Type<?> getType()

Description copied from interface: PropertyState

Determine the type of this property

Returns:

the type of this property

isArray

public boolean isArray()

false

getValue

@NotNull
public <S> S getValue(Type<S> type)

Description copied from interface: PropertyState

Value of this property. The type of the return value is determined by the target type argument. If type.isArray() is true, this method returns an Iterable of the base type of type containing all values of this property. If the target type is not the same as the type of this property an attempt is made to convert the value to the target type. If the conversion fails an exception is thrown. The actual conversions which take place are those defined in the org.apache.jackrabbit.oak.plugins.value.Conversions class.

Specified by:

getValue in interface PropertyState

Overrides:

getValue in class EmptyPropertyState

Parameters:

type - target type

Returns:

An empty list if type.isArray() is true.

Throws:

java.lang.IllegalArgumentException - if type is not one of the values defined in Type.

getValue

@NotNull
public <S> S getValue(Type<S> type,
                               int index)

Description copied from interface: PropertyState

Value at the given index. The type of the return value is determined by the target type argument. If the target type is not the same as the type of this property an attempt is made to convert the value to the target type. If the conversion fails an exception is thrown. The actual conversions which take place are those defined in the org.apache.jackrabbit.oak.plugins.value.Conversions class.

Specified by:

getValue in interface PropertyState

Overrides:

getValue in class EmptyPropertyState
