Constructor Detail

FloatBuffer

FloatBuffer(int capacity,
            int limit,
            int position,
            int mark)
Method Detail

allocate

public static FloatBuffer allocate(int capacity)
Allocates a new FloatBuffer object with a given capacity.

wrap

public static final FloatBuffer wrap(float[] array,
                                     int offset,
                                     int length)
Wraps a float array into a FloatBuffer object.

wrap

public static final FloatBuffer wrap(float[] array)
Wraps a float array into a FloatBuffer object.

get

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.

get

public FloatBuffer get(float[] dst)
This method transfers floats from this buffer into the given destination array.

put

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.

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.

put

public final FloatBuffer put(float[] src)
Writes the content of the the float array src into the buffer.

hasArray

public final boolean hasArray()
Tells whether ot not this buffer is backed by an accessible float array.

array

public final float[] array()
Returns the float array that backs this buffer.

arrayOffset

public final int arrayOffset()
Returns the offset within this buffer's backing array of the first element.

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.

equals

public boolean equals(java.lang.Object obj)
Checks if this buffer is equal to obj.

compareTo

public int compareTo(java.lang.Object obj)
Compares two FloatBuffer objects.

Specified by:
compareTo in interface java.lang.Comparable

order

public abstract ByteOrder order()
Returns the byte order of this buffer.

get

public abstract float get()
Reads the float at this buffer's current position, and then increments the position.

put

public abstract FloatBuffer put(float b)
Writes the float at this buffer's current position, and then increments the position.

get

public abstract float get(int index)
Absolute get method.

put

public abstract FloatBuffer put(int index,
                                float b)
Absolute put method.

compact

public abstract FloatBuffer compact()
Compacts this buffer.

isDirect

public abstract boolean isDirect()
Tells wether or not this buffer is direct.

slice

public abstract FloatBuffer slice()
Creates a new FloatBuffer whose content is a shared subsequence of this buffer's content.

duplicate

public abstract FloatBuffer duplicate()
Creates a new FloatBuffer that shares this buffer's content.

asReadOnlyBuffer

public abstract FloatBuffer asReadOnlyBuffer()
Creates a new read-only FloatBuffer that shares this buffer's content.
