and then increments the position.
|
long | get(int index) - Absolute get method.
|
LongBuffer | get(long[] dst) - This method transfers
long s from this buffer into the given
destination array.
|
LongBuffer | get(long[] dst, int offset, int length) - This method transfers
long s from this buffer into the given
destination array.

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

long array into a LongBuffer
object.
|

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