public static IntBuffer allocate(int capacity)
capacity - the capacity of the new buffer.IllegalArgumentException - if capacity is less than zero.public static IntBuffer wrap(int[] array)
Calling this method has the same effect as
wrap(array, 0, array.length).
array - the int array which the new buffer will be based on.public static IntBuffer wrap(int[] array, int start, int len)
The new buffer's position will be start, limit will be
start + len, capacity will be the length of the array.
array - the int array which the new buffer will be based on.start - the start index, must not be negative and not greater than
array.lengthlen - the length, must not be negative and not greater than
array.length - start.IndexOutOfBoundsException - if either start or len is invalid.public final int[] array()
ReadOnlyBufferException - if this buffer is based on an array, but it is read-only.UnsupportedOperationException - if this buffer is not based on an array.public final int arrayOffset()
The offset is the index of the array corresponds to the zero position of the buffer.
ReadOnlyBufferException - if this buffer is based on an array, but it is read-only.UnsupportedOperationException - if this buffer is not based on an array.public abstract IntBuffer asReadOnlyBuffer()
The returned buffer is guaranteed to be a new instance, even this buffer is read-only itself. The new buffer's position, limit, capacity and mark are the same as this buffer's.
The new buffer shares its content with this buffer, which means this buffer's change of content will be visible to the new buffer. The two buffer's position, limit and mark are independent.
public abstract IntBuffer compact()
The remaining ints will be moved to the head of the buffer, starting from
position zero. Then the position is set to remaining(); the
limit is set to capacity; the mark is cleared.
ReadOnlyBufferException - if no changes may be made to the contents of this buffer.public int compareTo(IntBuffer otherBuffer)
compareTo in interface Comparable<IntBuffer>otherBuffer - another int buffer.other; 0 if this
equals to other; a positive value if this is greater
than other.ClassCastException - if other is not an int buffer.public abstract IntBuffer duplicate()
The duplicated buffer's position, limit, capacity and mark are the same as this buffer. The duplicated buffer's read-only property and byte order are the same as this buffer's.
The new buffer shares its content with this buffer, which means either buffer's change of content will be visible to the other. The two buffer's position, limit and mark are independent.
public boolean equals(Object other)
If other is not a int buffer then false is returned. Two
int buffers are equal if and only if their remaining ints are exactly the
same. Position, limit, capacity and mark are not considered.
public abstract int get()
BufferUnderflowException - if the position is equal or greater than limit.public IntBuffer get(int[] dest)
Calling this method has the same effect as
get(dest, 0, dest.length).
dest - the destination int array.BufferUnderflowException - if dest.length is greater than remaining().public IntBuffer get(int[] dest, int off, int len)
dest - the target int array.off - the offset of the int array, must not be negative and not
greater than dest.length.len - the number of ints to read, must be no less than zero and not
greater than dest.length - off.IndexOutOfBoundsException - if either off or len is invalid.BufferUnderflowException - if len is greater than remaining().public abstract int get(int index)
index - the index, must not be negative and less than limit.IndexOutOfBoundsException - if index is invalid.public final boolean hasArray()
true if this buffer is based on a int array and provides
read/write access, false otherwise.public int hashCode()
public abstract boolean isDirect()
An int buffer is direct if it is based on a byte buffer and the byte buffer is direct.
true if this buffer is direct, false otherwise.public abstract ByteOrder order()
If this buffer is not based on a byte buffer, then always return the platform's native byte order.

The sliced buffer's capacity will be this buffer's remaining(),
and its zero position will correspond to this buffer's current position.
The new buffer's position will be 0, limit will be its capacity, and its
mark is cleared. The new buffer's read-only property and byte order are
same as this buffer's.
The new buffer shares its content with this buffer, which means either buffer's change of content will be visible to the other. The two buffer's position, limit and mark are independent.
