int at this buffer's current position,
and then increments the position.
|
IntBuffer | put(int index, int b) - Absolute put method.
|
IntBuffer | put(int[] src) - Writes the content of the the
int array src
into the buffer.
|
IntBuffer | put(int[] src, int offset, int length) - Writes the content of the the
int array src
into the buffer.
|
IntBuffer | put(IntBuffer src) - Writes the content of the the
IntBUFFER src
into the buffer.
|
IntBuffer | slice() - Creates a new
IntBuffer whose content is a shared
subsequence of this buffer's content.
|

int array into a IntBuffer
object.
|

int array into a IntBuffer
object.

allocate
public static IntBuffer allocate(int capacity)
Allocates a new IntBuffer
object with a given capacity.
duplicate
public IntBuffer duplicate()
Creates a new IntBuffer
that shares this buffer's
content.
equals
public boolean equals(Object obj)
Checks if this buffer is equal to obj.
- equals in interface Object
get
public int get()
Reads the int
at this buffer's current position,
and then increments the position.
BufferUnderflowException
- If there are no remaining
int
s in this buffer.
get
public IntBuffer get(int[] dst)
This method transfers int
s from this buffer into the given
destination array.
dst
- The byte array to write into.
BufferUnderflowException
- If there are fewer than dst.length
int
s remaining in this buffer.
get
public IntBuffer get(int[] dst,
int offset,
int length)
This method transfers int
s from this buffer into the given
destination array. Before the transfer, it checks if there are fewer than
length int
s 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.
BufferUnderflowException
- If there are fewer than length
int
s remaining in this buffer.IndexOutOfBoundsException
- If the preconditions on the offset
and length parameters do not hold.
hasArray
public final boolean hasArray()
Tells whether ot not this buffer is backed by an accessible
int
array.
hashCode
public int hashCode()
Calculates a hash code for this buffer.
This is done with 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 interface Object
- the hash code
isDirect
public boolean isDirect()
Tells wether or not this buffer is direct.
put
public final IntBuffer put(int[] src)
Writes the content of the the int array
src
into the buffer.
src
- The array to copy into the buffer.
BufferOverflowException
- If there is insufficient space in this
buffer for the remaining int
s in the source array.ReadOnlyBufferException
- If this buffer is read-only.
put
public IntBuffer put(int[] src,
int offset,
int length)
Writes the content of the the 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 int
s in the source array.IndexOutOfBoundsException
- If the preconditions on the offset
and length parameters do not holdReadOnlyBufferException
- If this buffer is read-only.
put
public IntBuffer put(IntBuffer src)
Writes the content of the the 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 int
s in the source buffer.IllegalArgumentException
- If the source buffer is this buffer.ReadOnlyBufferException
- If this buffer is read-only.
slice
public IntBuffer slice()
Creates a new IntBuffer
whose content is a shared
subsequence of this buffer's content.
wrap
public static final IntBuffer wrap(int[] array)
Wraps a int
array into a IntBuffer
object.
wrap
public static final IntBuffer wrap(int[] array,
int offset,
int length)
Wraps a int
array into a IntBuffer
object.
IndexOutOfBoundsException
- If the preconditions on the offset
and length parameters do not hold
