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

short array into a ShortBuffer
object.
|

allocate
public static ShortBuffer allocate(int capacity)
Allocates a new ShortBuffer
object with a given capacity.
duplicate
public ShortBuffer duplicate()
Creates a new ShortBuffer
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 short get()
Reads the short
at this buffer's current position,
and then increments the position.
BufferUnderflowException
- If there are no remaining
short
s in this buffer.
get
public short get(int index)
Absolute get method.
IndexOutOfBoundsException
- If index is negative or not smaller
than the buffer's limit.
get
public ShortBuffer get(short[] dst)
This method transfers short
s from this buffer into the given
destination array.
dst
- The byte array to write into.
BufferUnderflowException
- If there are fewer than dst.length
short
s remaining in this buffer.
get
public ShortBuffer get(short[] dst,
int offset,
int length)
This method transfers short
s from this buffer into the given
destination array. Before the transfer, it checks if there are fewer than
length short
s remaining in this buffer.
dst
- The destination arrayoffset
- The offset within the array of the first short
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
short
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
short
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 ShortBuffer put(short[] src)
Writes the content of the the short 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 short
s in the source array.ReadOnlyBufferException
- If this buffer is read-only.
put
public ShortBuffer put(short[] src,
int offset,
int length)
Writes the content of the the short 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 short
s in the source array.IndexOutOfBoundsException
- If the preconditions on the offset
and length parameters do not holdReadOnlyBufferException
- If this buffer is read-only.
slice
public ShortBuffer slice()
Creates a new ShortBuffer
whose content is a shared
subsequence of this buffer's content.
wrap
public static final ShortBuffer wrap(short[] array)
Wraps a short
array into a ShortBuffer
object.
wrap
public static final ShortBuffer wrap(short[] array,
int offset,
int length)
Wraps a short
array into a ShortBuffer
object.
IndexOutOfBoundsException
- If the preconditions on the offset
and length parameters do not hold
