Method Details

type

Class<? extends PNumberArray> type()

Description copied from interface: Array

Returns the canonical AlgART type of this array: the class of one of 9 basic interfaces, describing all kinds of AlgART arrays for 8 primitive and any non-primitive element types. More precisely, returns:

• BitArray.class, if this object is an instance of BitArray,
• CharArray.class, if this object is an instance of CharArray,
• ByteArray.class, if this object is an instance of ByteArray,
• ShortArray.class, if this object is an instance of ShortArray,
• IntArray.class, if this object is an instance of IntArray,
• LongArray.class, if this object is an instance of LongArray,
• FloatArray.class, if this object is an instance of FloatArray,
• DoubleArray.class, if this object is an instance of DoubleArray,
• ObjectArray.class, if this object is an instance of ObjectArray.

There is a guarantee that this method works very quickly (usually it just returns a constant value).

Specified by:

type in interface Array

Specified by:

type in interface PArray

Returns:

canonical AlgART type of this array.

updatableType

Class<? extends UpdatablePNumberArray> updatableType()

Description copied from interface: Array

Returns the canonical updatable AlgART type of arrays with the same element types: the class of one of 9 basic interfaces, describing all kinds of updatable AlgART arrays for 8 primitive and any non-primitive element types. More precisely, returns:

• UpdatableBitArray.class, if this object is an instance of BitArray,
• UpdatableCharArray.class, if this object is an instance of CharArray,
• UpdatableByteArray.class, if this object is an instance of ByteArray,
• UpdatableShortArray.class, if this object is an instance of ShortArray,
• UpdatableIntArray.class, if this object is an instance of IntArray,
• UpdatableLongArray.class, if this object is an instance of LongArray,
• UpdatableFloatArray.class, if this object is an instance of FloatArray,
• UpdatableDoubleArray.class, if this object is an instance of DoubleArray,
• UpdatableObjectArray.class, if this object is an instance of ObjectArray.

There is a guarantee that this method works very quickly (usually it just returns a constant value).

Specified by:

updatableType in interface Array

Specified by:

updatableType in interface PArray

Returns:

canonical AlgART type of an updatable array of the same kind.

mutableType

Class<? extends MutablePNumberArray> mutableType()

Description copied from interface: Array

Returns the canonical resizable AlgART type of arrays with the same element types: the class of one of 9 basic interfaces, describing all kinds of resizable AlgART arrays for 8 primitive and any non-primitive element types. More precisely, returns:

• MutableBitArray.class, if this object is an instance of BitArray,
• MutableCharArray.class, if this object is an instance of CharArray,
• MutableByteArray.class, if this object is an instance of ByteArray,
• MutableShortArray.class, if this object is an instance of ShortArray,
• MutableIntArray.class, if this object is an instance of IntArray,
• MutableLongArray.class, if this object is an instance of LongArray,
• MutableFloatArray.class, if this object is an instance of FloatArray,
• MutableDoubleArray.class, if this object is an instance of DoubleArray,
• MutableObjectArray.class, if this object is an instance of ObjectArray.

There is a guarantee that this method works very quickly (usually it just returns a constant value).
