public static ShortBuffer allocate(int capacity)
ShortBuffer object with a given capacity.
public static final ShortBuffer wrap(short[] array,
int offset,
int length)
short array into a ShortBuffer
object.
IndexOutOfBoundsException - If the preconditions on the offset
and length parameters do not holdpublic static final ShortBuffer wrap(short[] array)
short array into a ShortBuffer
object.
public ShortBuffer get(short[] dst,
int offset,
int length)
shorts from this buffer into the given
destination array. Before the transfer, it checks if there are fewer than
length shorts 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
shorts remaining in this buffer.
IndexOutOfBoundsException - If the preconditions on the offset
and length parameters do not hold.public ShortBuffer get(short[] dst)
shorts from this buffer into the given
destination array.
dst - The byte array to write into.
BufferUnderflowException - If there are fewer than dst.length
shorts remaining in this buffer.public ShortBuffer put(ShortBuffer src)
ShortBUFFER 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 shorts in the source buffer.
IllegalArgumentException - If the source buffer is this buffer.
ReadOnlyBufferException - If this buffer is read-only.
public ShortBuffer put(short[] src,
int offset,
int length)
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 shorts 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 ShortBuffer put(short[] src)
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 shorts in the source array.
ReadOnlyBufferException - If this buffer is read-only.public final boolean hasArray()
short array.
public final short[] array()
short 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(ShortBuffer other)
ShortBuffer objects.
compareTo in interface Comparable<ShortBuffer>other - the object to be compared
ClassCastException - If obj is not an object derived from
ShortBuffer.public abstract ByteOrder order()
public abstract short get()

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