public abstract class AbstractMatrix extends PersistentObject
Abstract base class for arbitrary-dimensional matrices holding objects or primitive data types such as int, float, etc. First see the package summary and javadoc tree view to get the broad picture.

Note that this implementation is not synchronized.

    void
    ensureCapacity(int minNonZeros)
    Ensures that the receiver can hold at least the specified number of non-zero (non-null) cells without needing to allocate new internal memory.
    protected boolean
    isView()
    Returns whether the receiver is a view or not.
    abstract int
    size()
    Returns the number of cells.

    • ensureCapacity

      public void ensureCapacity(int minNonZeros)
      Ensures that the receiver can hold at least the specified number of non-zero (non-null) cells without needing to allocate new internal memory. If necessary, allocates new internal memory and increases the capacity of the receiver.

      This default implementation does nothing. Override this method if necessary.

      Parameters:
      minNonZeros - the desired minimum number of non-zero (non-null) cells.

    • isView

      protected boolean isView()
      Returns whether the receiver is a view or not.

    • size

      public abstract int size()
      Returns the number of cells.

    • trimToSize

      public void trimToSize()
      Releases any superfluous internal memory. An application can use this operation to minimize the storage of the receiver.

      This default implementation does nothing. Override this method if necessary.
