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

float array into a FloatBuffer
object.
|

float array into a FloatBuffer
object.

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