public DoublePropertyState(java.lang.String name,
                           double value)

Method Detail

doubleProperty

public static PropertyState doubleProperty(java.lang.String name,
                                           double value)

Create a PropertyState from a double.

Parameters:

name - The name of the property state

value - The value of the property state

Returns:

The new property state of type Type.DOUBLE

getValue

public java.lang.Double getValue()

The value of this property

Returns:

Value of this property

getConverter

public Conversions.Converter getConverter()

Create a converter for converting the value of this property to other types.

Returns:

A converter for the value of this property

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()

Description copied from interface: PropertyState

Determine whether the value is an array of atoms

Specified by:

isArray in interface PropertyState

Overrides:

isArray in class EmptyPropertyState

Returns:

false

getValue

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 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

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 Conversions class.

Specified by:

getValue in interface PropertyState

Overrides:

getValue in class EmptyPropertyState

Parameters:

type - target type

Returns:

the value of this property at the given index

Throws:

java.lang.IllegalArgumentException - if type.isArray is true

java.lang.IndexOutOfBoundsException - if index != 0

size

public long size()

Description copied from interface: PropertyState

The size of the value of this property.

Specified by:

size in interface PropertyState

Overrides:

size in class EmptyPropertyState

Returns:

getString().length()

size

public long size(int index)

Description copied from interface: PropertyState

The size of the value at the given index.

Specified by:

size in interface PropertyState

Overrides:

Returns:

size

Throws:

java.lang.IndexOutOfBoundsException - if index != 0

count

public int count()

Description copied from interface: PropertyState

The number of values of this property. 1 for atoms.

Specified by:

count in interface PropertyState

Overrides:

count in class EmptyPropertyState

Returns:

1
