public abstract class AbstractUpdatableCharArray extends AbstractCharArray implements UpdatableCharArray
Implementation of almost all basic functions of UpdatableCharArray interface.
The only CharArray.getChar(long) and UpdatableCharArray.setChar(long, char) methods
are not defined in this class;
all other methods are implemented via calls of these 2 methods.

| Constructor Detail |

protected AbstractUpdatableCharArray(long initialCapacity,
long initialLength,
boolean underlyingArraysAreParallel,
Array... underlyingArrays)
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.
initialCapacity - initial capacity of the array.initialLength - initial length of the array.underlyingArraysAreParallel - see the same argument of
AbstractCharArray.AbstractCharArray(long, long, boolean, Array...).underlyingArrays - see the same argument of
AbstractArray.AbstractArray(long, long, Array...).java.lang.NullPointerException - if underlyingArrays argument or some of underlyingArrays[k]
elements is null.java.lang.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.
protected AbstractUpdatableCharArray(long initialCapacityAndLength,
boolean underlyingArraysAreParallel,
Array... underlyingArrays)
AbstractUpdatableCharArray(long, long, boolean, Array...),
where both initialCapacity and initialLength arguments are equal to
initialCapacityAndLength.
initialCapacityAndLength - initial capacity and length of the array.underlyingArraysAreParallel - see AbstractUpdatableCharArray(long, long, boolean, Array...).underlyingArrays - see AbstractUpdatableCharArray(long, long, boolean, Array...)java.lang.IllegalArgumentException - if the passed argument are illegal (negative).| Method Detail |

and with overridden methods AbstractCharArray.getChar(long), setChar(long, char),

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 AbstractCharArray.loadResources(ArrayContext, long, long),
AbstractCharArray.flushResources(ArrayContext, long, long, boolean) and
AbstractCharArray.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(),

this method works as for all other array types.

containing all characters of the array, you may use
