public static IntBuffer allocate(int capacity)
IntBuffer object with a given capacity.
public static final IntBuffer wrap(int[] array,
int offset,
int length)
int array into a IntBuffer
object.

and length parameters do not holdpublic static final IntBuffer wrap(int[] array)
int array into a IntBuffer
object.
public IntBuffer get(int[] dst,
int offset,
int length)
ints from this buffer into the given
destination array. Before the transfer, it checks if there are fewer than
length ints remaining in this buffer.
dst - The destination arrayoffset - The offset within the array of the first int
to be written; must be non-negative and no larger than dst.length.length - The maximum number of bytes to be written to the given array;
must be non-negative and no larger than dst.length - offset.

ints remaining in this buffer.
IndexOutOfBoundsException - If the preconditions on the offset
and length parameters do not hold.public IntBuffer get(int[] dst)
ints from this buffer into the given
destination array.
dst - The byte array to write into.
BufferUnderflowException - If there are fewer than dst.length
ints remaining in this buffer.public IntBuffer put(IntBuffer src)
IntBUFFER src
into the buffer. Before the transfer, it checks if there is fewer than
src.remaining() space remaining in this buffer.
src - The source data.
BufferOverflowException - If there is insufficient space in this
buffer for the remaining ints in the source buffer.
IllegalArgumentException - If the source buffer is this buffer.
ReadOnlyBufferException - If this buffer is read-only.
public IntBuffer put(int[] src,
int offset,
int length)
int array src
into the buffer. Before the transfer, it checks if there is fewer than
length space remaining in this buffer.
src - The array to copy into the buffer.offset - The offset within the array of the first byte to be read;
must be non-negative and no larger than src.length.length - The number of bytes to be read from the given array;
must be non-negative and no larger than src.length - offset.
BufferOverflowException - If there is insufficient space in this
buffer for the remaining ints in the source array.
IndexOutOfBoundsException - If the preconditions on the offset
and length parameters do not hold
ReadOnlyBufferException - If this buffer is read-only.public final IntBuffer put(int[] src)
int array src
into the buffer.
src - The array to copy into the buffer.

ReadOnlyBufferException - If this buffer is read-only.public final boolean hasArray()
int array.
public final int[] array()
int array that backs this buffer.
ReadOnlyBufferException - If this buffer is read-only.
UnsupportedOperationException - If this buffer is not backed
by an accessible array.public final int arrayOffset()
ReadOnlyBufferException - If this buffer is read-only.
UnsupportedOperationException - If this buffer is not backed
by an accessible array.public int hashCode()
int arithmetic,
where ** represents exponentiation, by this formula:s[position()] + 31 + (s[position()+1] + 30)*31**1 + ... +
(s[limit()-1]+30)*31**(limit()-1).
Where s is the buffer data. Note that the hashcode is dependent
on buffer content, and therefore is not useful if the buffer
content may change.
hashCode in class ObjectObject.equals(Object),
System.identityHashCode(Object)public boolean equals(Object obj)
equals in class Objectobj - the Object to compare to
Object.hashCode()public int compareTo(IntBuffer other)
IntBuffer objects.
compareTo in interface Comparable<IntBuffer>other - the object to be compared
ClassCastException - If obj is not an object derived from
IntBuffer.public abstract ByteOrder order()
public abstract int get()

and then increments the position.
BufferUnderflowException - If there are no remaining
ints in this buffer.public abstract IntBuffer put(int b)
int at this buffer's current position,
and then increments the position.
BufferOverflowException - If there no remaining
ints in this buffer.
ReadOnlyBufferException - If this buffer is read-only.public abstract int get(int index)
IndexOutOfBoundsException - If index is negative or not smaller
than the buffer's limit.
public abstract IntBuffer put(int index,
int b)
IndexOutOfBoundsException - If index is negative or not smaller
than the buffer's limit.
