Class FloatBuffer

public static FloatBuffer allocate(int capacity)

Allocates a new FloatBuffer object with a given capacity.

public final float[] array()

Returns the float array that backs this buffer.

Throws:

ReadOnlyBufferException - If this buffer is read-only.

UnsupportedOperationException - If this buffer is not backed by an accessible array.

public final int arrayOffset()

Returns the offset within this buffer's backing array of the first element.

Throws:

ReadOnlyBufferException - If this buffer is read-only.

UnsupportedOperationException - If this buffer is not backed by an accessible array.

public abstract FloatBuffer asReadOnlyBuffer()

Creates a new read-only FloatBuffer that shares this buffer's content.

public abstract FloatBuffer compact()

Compacts this buffer.

Throws:

ReadOnlyBufferException - If this buffer is read-only.

public int compareTo(FloatBuffer other)

Compares two FloatBuffer objects.

Throws:

ClassCastException - If obj is not an object derived from FloatBuffer.

public abstract FloatBuffer duplicate()

Creates a new FloatBuffer that shares this buffer's content.

public boolean equals(Object obj)

Checks if this buffer is equal to obj.

Overrides:

equals in interface Object

public abstract float get()

Reads the float at this buffer's current position, and then increments the position.

Throws:

BufferUnderflowException - If there are no remaining floats in this buffer.

public FloatBuffer get(float[] dst)

This method transfers floats from this buffer into the given destination array.

Parameters:

dst - The byte array to write into.

Throws:

BufferUnderflowException - If there are fewer than dst.length floats remaining in this buffer.

public FloatBuffer get(float[] dst,
                       int offset,
                       int length)

This method transfers floats from this buffer into the given destination array. Before the transfer, it checks if there are fewer than length floats remaining in this buffer.

Parameters:

dst - The destination array

offset - 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.

Throws:

BufferUnderflowException - If there are fewer than length floats remaining in this buffer.

IndexOutOfBoundsException - If the preconditions on the offset and length parameters do not hold.

public abstract float get(int index)

Absolute get method.

Throws:

IndexOutOfBoundsException - If index is negative or not smaller than the buffer's limit.

public final boolean hasArray()

Tells whether ot not this buffer is backed by an accessible float array.

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.

Overrides:

hashCode in interface Object

Returns:

the hash code

public abstract boolean isDirect()

Tells wether or not this buffer is direct.

public abstract ByteOrder order()

Returns the byte order of this buffer.

public abstract FloatBuffer put(float b)

Writes the float at this buffer's current position, and then increments the position.

Throws:

BufferOverflowException - If there no remaining floats in this buffer.

ReadOnlyBufferException - If this buffer is read-only.

public final FloatBuffer put(float[] src)

Writes the content of the the float array src into the buffer.

Parameters:

src - The array to copy into the buffer.

Throws:

BufferOverflowException - If there is insufficient space in this buffer for the remaining floats in the source array.

ReadOnlyBufferException - If this buffer is read-only.

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.

Parameters:

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.

Throws:

BufferOverflowException - If there is insufficient space in this buffer for the remaining floats 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 abstract FloatBuffer put(int index,
                                float b)

Absolute put method.

Throws:

IndexOutOfBoundsException - If index is negative or not smaller than the buffer's limit.

ReadOnlyBufferException - If this buffer is read-only.

public FloatBuffer put(FloatBuffer src)

Writes the content of the the FloatBUFFER src into the buffer. Before the transfer, it checks if there is fewer than src.remaining() space remaining in this buffer.

Parameters:

src - The source data.

Throws:

BufferOverflowException - If there is insufficient space in this buffer for the remaining floats in the source buffer.

IllegalArgumentException - If the source buffer is this buffer.

ReadOnlyBufferException - If this buffer is read-only.

public abstract FloatBuffer slice()

Creates a new FloatBuffer whose content is a shared subsequence of this buffer's content.

public static final FloatBuffer wrap(float[] array)

Wraps a float array into a FloatBuffer object.

public static final FloatBuffer wrap(float[] array,
                                     int offset,
                                     int length)

Wraps a float array into a FloatBuffer object.

Throws:

IndexOutOfBoundsException - If the preconditions on the offset and length parameters do not hold
