Constructor Details

AbstractUpdatableFloatArray

protected AbstractUpdatableFloatArray(long initialCapacity,
 long initialLength,
 boolean underlyingArraysAreParallel,
 Array... underlyingArrays)

Creates an updatable array with the given initial capacity and length.

This array is not new by default. This is correct usually, because this class is often used for creating a view of another data. However, if the instance if this class does not depend on any other data sources, you may call setNewStatus(true) in the constructor of your subclass.

Parameters:

initialCapacity - initial capacity of the array.

initialLength - initial length of the array.

underlyingArraysAreParallel - see the same argument of AbstractFloatArray(long, long, boolean, Array...).

underlyingArrays - see the same argument of AbstractArray(long, long, Array...).

Throws:

NullPointerException - if underlyingArrays argument or some of underlyingArrays[k] elements is null.

IllegalArgumentException - if the initialCapacity or initialLength arguments are illegal (negative, or capacity < length).

SizeMismatchException - if underlyingArraysAreParallel=true, underlyingArrays.length>1 and some of passed arrays have different lengths.

AbstractUpdatableFloatArray

protected AbstractUpdatableFloatArray(long initialCapacityAndLength,
 boolean underlyingArraysAreParallel,
 Array... underlyingArrays)

Equivalent to the constructor AbstractUpdatableFloatArray(long, long, boolean, Array...), where both initialCapacity and initialLength arguments are equal to initialCapacityAndLength.

Parameters:

initialCapacityAndLength - initial capacity and length of the array.

underlyingArraysAreParallel - see AbstractUpdatableFloatArray(long, long, boolean, Array...).

underlyingArrays - see AbstractUpdatableFloatArray(long, long, boolean, Array...)

Throws:

IllegalArgumentException - if the passed argument are illegal (negative).

Method Details

subArray

public UpdatableFloatArray subArray(long fromIndex,
 long toIndex)

This implementation returns new instance of AbstractUpdatableFloatArray with the same memory model and underlying arrays, that were passed to the constructor of this instance, and with overridden methods AbstractFloatArray.getFloat(long), setFloat(long, float), AbstractFloatArray.getData(long, Object, int, int) and setData(long, Object, int, int) calling the same methods of this instance with corresponding corrections of the arguments.

The returned instance also have overridden methods AbstractFloatArray.loadResources(ArrayContext, long, long), AbstractFloatArray.flushResources(ArrayContext, long, long, boolean) and AbstractFloatArray.freeResources(ArrayContext, long, long, boolean), that also call the same methods of this instance with corresponding correction of their fromIndex argument.

The returned instance also have overridden method AbstractArray.isLazy(), that just calls the same methods of this instance with the same arguments.

Parameters:

index - index of element to replace.

value - element to be stored at the specified position.

See Also:

Description copied from interface: UpdatablePArray

Sets the element #index with conversion from long, as (xxx)value for numeric element type xxx (byte, short, int, long, float, double or char), or as value!=0 for boolean element type.

Depending on the specific subinterface implemented by the object, this method is equivalent to one of the following calls:

• for UpdatableBitArray: setBit(index, value != 0);
• for UpdatableCharArray: setChar(index, (char) value);
• for UpdatableByteArray: setByte(index, (byte) value);
