| Methods Summary |
|---|
| java.lang.Object | _array()
if (hasArray()) {
return array();
}
return null;
|
| int | _arrayOffset()
if (hasArray()) {
return arrayOffset();
}
return 0;
|
| public static java.nio.FloatBuffer | allocate(int capacity)Creates a float buffer based on a newly allocated float array.
if (capacity < 0) {
throw new IllegalArgumentException();
}
return BufferFactory.newFloatBuffer(capacity);
|
| public final float[] | array()Returns the float array which this buffer is based on, if there is one.
return protectedArray();
|
| public final int | arrayOffset()Returns the offset of the float array which this buffer is based on, if
there is one.
The offset is the index of the array and corresponds to the zero position
of the buffer.
return protectedArrayOffset();
|
| public abstract java.nio.FloatBuffer | asReadOnlyBuffer()Returns a read-only buffer that shares its content with this buffer.
The returned buffer is guaranteed to be a new instance, even if this
buffer is read-only itself. The new buffer's position, limit, capacity
and mark are the same as this buffer.
The new buffer shares its content with this buffer, which means this
buffer's change of content will be visible to the new buffer. The two
buffer's position, limit and mark are independent.
|
| public abstract java.nio.FloatBuffer | compact()Compacts this float buffer.
The remaining floats will be moved to the head of the buffer, starting
from position zero. Then the position is set to {@code remaining()}; the
limit is set to capacity; the mark is cleared.
|
| public int | compareTo(java.nio.FloatBuffer otherBuffer)Compare the remaining floats of this buffer to another float buffer's
remaining floats.
int compareRemaining = (remaining() < otherBuffer.remaining()) ? remaining()
: otherBuffer.remaining();
int thisPos = position;
int otherPos = otherBuffer.position;
// BEGIN android-changed
float thisFloat, otherFloat;
while (compareRemaining > 0) {
thisFloat = get(thisPos);
otherFloat = otherBuffer.get(otherPos);
// checks for float and NaN inequality
if ((thisFloat != otherFloat)
&& ((thisFloat == thisFloat) || (otherFloat == otherFloat))) {
return thisFloat < otherFloat ? -1 : 1;
}
thisPos++;
otherPos++;
compareRemaining--;
}
// END android-changed
return remaining() - otherBuffer.remaining();
|
| public abstract java.nio.FloatBuffer | duplicate()Returns a duplicated buffer that shares its content with this buffer.
The duplicated buffer's position, limit, capacity and mark are the same
as this buffer. The duplicated buffer's read-only property and byte order
are same as this buffer too.
The new buffer shares its content with this buffer, which means either
buffer's change of content will be visible to the other. The two buffer's
position, limit and mark are independent.
|
| public boolean | equals(java.lang.Object other)Checks whether this float buffer is equal to another object.
If {@code other} is not a float buffer then {@code false} is returned.
Two float buffers are equal if and only if their remaining floats are
exactly the same. Position, limit, capacity and mark are not considered.
if (!(other instanceof FloatBuffer)) {
return false;
}
FloatBuffer otherBuffer = (FloatBuffer) other;
if (remaining() != otherBuffer.remaining()) {
return false;
}
int myPosition = position;
int otherPosition = otherBuffer.position;
boolean equalSoFar = true;
while (equalSoFar && (myPosition < limit)) {
equalSoFar = get(myPosition++) == otherBuffer.get(otherPosition++);
}
return equalSoFar;
|
| public abstract float | get()Returns the float at the current position and increases the position by
1.
|
| public java.nio.FloatBuffer | get(float[] dest)Reads floats from the current position into the specified float array and
increases the position by the number of floats read.
Calling this method has the same effect as
{@code get(dest, 0, dest.length)}.
return get(dest, 0, dest.length);
|
| public java.nio.FloatBuffer | get(float[] dest, int off, int len)Reads floats from the current position into the specified float array,
starting from the specified offset, and increases the position by the
number of floats read.
int length = dest.length;
if (off < 0 || len < 0 || (long)off + (long)len > length) {
throw new IndexOutOfBoundsException();
}
if (len > remaining()) {
throw new BufferUnderflowException();
}
for (int i = off; i < off + len; i++) {
dest[i] = get();
}
return this;
|
| public abstract float | get(int index)Returns a float at the specified index; the position is not changed.
|
| public final boolean | hasArray()Indicates whether this buffer is based on a float array and is
read/write.
return protectedHasArray();
|
| public int | hashCode()Calculates this buffer's hash code from the remaining chars. The
position, limit, capacity and mark don't affect the hash code.
int myPosition = position;
int hash = 0;
while (myPosition < limit) {
hash = hash + Float.floatToIntBits(get(myPosition++));
}
return hash;
|
| public abstract boolean | isDirect()Indicates whether this buffer is direct. A direct buffer will try its
best to take advantage of native memory APIs and it may not stay in the
Java heap, so it is not affected by garbage collection.
A float buffer is direct if it is based on a byte buffer and the byte
buffer is direct.
|
| public abstract java.nio.ByteOrder | order()Returns the byte order used by this buffer when converting floats from/to
bytes.
If this buffer is not based on a byte buffer, then always return the
platform's native byte order.
|
| abstract float[] | protectedArray()Child class implements this method to realize {@code array()}.
|
| abstract int | protectedArrayOffset()Child class implements this method to realize {@code arrayOffset()}.
|
| abstract boolean | protectedHasArray()Child class implements this method to realize {@code hasArray()}.
|
| public abstract java.nio.FloatBuffer | put(float f)Writes the given float to the current position and increases the position
by 1.
|
| public final java.nio.FloatBuffer | put(float[] src)Writes floats from the given float array to the current position and
increases the position by the number of floats written.
Calling this method has the same effect as
{@code put(src, 0, src.length)}.
return put(src, 0, src.length);
|
| public java.nio.FloatBuffer | put(float[] src, int off, int len)Writes floats from the given float array, starting from the specified
offset, to the current position and increases the position by the number
of floats written.
int length = src.length;
if (off < 0 || len < 0 || (long)off + (long)len > length) {
throw new IndexOutOfBoundsException();
}
if (len > remaining()) {
throw new BufferOverflowException();
}
for (int i = off; i < off + len; i++) {
put(src[i]);
}
return this;
|
| public java.nio.FloatBuffer | put(java.nio.FloatBuffer src)Writes all the remaining floats of the {@code src} float buffer to this
buffer's current position, and increases both buffers' position by the
number of floats copied.
if (src == this) {
throw new IllegalArgumentException();
}
if (src.remaining() > remaining()) {
throw new BufferOverflowException();
}
float[] contents = new float[src.remaining()];
src.get(contents);
put(contents);
return this;
|
| public abstract java.nio.FloatBuffer | put(int index, float f)Writes a float to the specified index of this buffer; the position is not
changed.
|
| public abstract java.nio.FloatBuffer | slice()Returns a sliced buffer that shares its content with this buffer.
The sliced buffer's capacity will be this buffer's {@code remaining()},
and its zero position will correspond to this buffer's current position.
The new buffer's position will be 0, limit will be its capacity, and its
mark is cleared. The new buffer's read-only property and byte order are
same as this buffer's.
The new buffer shares its content with this buffer, which means either
buffer's change of content will be visible to the other. The two buffer's
position, limit and mark are independent.
|
| public java.lang.String | toString()Returns a string representing the state of this float buffer.
StringBuffer buf = new StringBuffer();
buf.append(getClass().getName());
buf.append(", status: capacity="); //$NON-NLS-1$
buf.append(capacity());
buf.append(" position="); //$NON-NLS-1$
buf.append(position());
buf.append(" limit="); //$NON-NLS-1$
buf.append(limit());
return buf.toString();
|
| public static java.nio.FloatBuffer | wrap(float[] array)Creates a new float buffer by wrapping the given float array.
Calling this method has the same effect as
{@code wrap(array, 0, array.length)}.
return wrap(array, 0, array.length);
|
| public static java.nio.FloatBuffer | wrap(float[] array, int start, int len)Creates a new float buffer by wrapping the given float array.
The new buffer's position will be {@code start}, limit will be
{@code start + len}, capacity will be the length of the array.
if (array == null) {
throw new NullPointerException();
}
if (start < 0 || len < 0 || (long)start + (long)len > array.length) {
throw new IndexOutOfBoundsException();
}
FloatBuffer buf = BufferFactory.newFloatBuffer(array);
buf.position = start;
buf.limit = start + len;
return buf;
