| Methods Summary |
|---|
| java.lang.Object | _array()
if (hasArray()) {
return array();
}
return null;
|
| int | _arrayOffset()
if (hasArray()) {
return arrayOffset();
}
return 0;
|
| public static java.nio.IntBuffer | allocate(int capacity)Creates an int buffer based on a newly allocated int array.
if (capacity < 0) {
throw new IllegalArgumentException();
}
return BufferFactory.newIntBuffer(capacity);
|
| public final int[] | array()Returns the int array which this buffer is based on, if there is one.
return protectedArray();
|
| public final int | arrayOffset()Returns the offset of the int array which this buffer is based on, if
there is one.
The offset is the index of the array corresponds to the zero position of
the buffer.
return protectedArrayOffset();
|
| public abstract java.nio.IntBuffer | asReadOnlyBuffer()Returns a read-only buffer that shares its content with this buffer.
The returned buffer is guaranteed to be a new instance, even this buffer
is read-only itself. The new buffer's position, limit, capacity and mark
are the same as this buffer's.
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.IntBuffer | compact()Compacts this int buffer.
The remaining ints 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.IntBuffer otherBuffer)Compares the remaining ints of this buffer to another int buffer's
remaining ints.
int compareRemaining = (remaining() < otherBuffer.remaining()) ? remaining()
: otherBuffer.remaining();
int thisPos = position;
int otherPos = otherBuffer.position;
// BEGIN android-changed
int thisInt, otherInt;
while (compareRemaining > 0) {
thisInt = get(thisPos);
otherInt = otherBuffer.get(otherPos);
if (thisInt != otherInt) {
return thisInt < otherInt ? -1 : 1;
}
thisPos++;
otherPos++;
compareRemaining--;
}
// END android-changed
return remaining() - otherBuffer.remaining();
|
| public abstract java.nio.IntBuffer | 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 the 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 boolean | equals(java.lang.Object other)Checks whether this int buffer is equal to another object.
If {@code other} is not a int buffer then {@code false} is returned. Two
int buffers are equal if and only if their remaining ints are exactly the
same. Position, limit, capacity and mark are not considered.
if (!(other instanceof IntBuffer)) {
return false;
}
IntBuffer otherBuffer = (IntBuffer) 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 int | get()Returns the int at the current position and increases the position by 1.
|
| public java.nio.IntBuffer | get(int[] dest)Reads ints from the current position into the specified int array and
increases the position by the number of ints read.
Calling this method has the same effect as
{@code get(dest, 0, dest.length)}.
return get(dest, 0, dest.length);
|
| public java.nio.IntBuffer | get(int[] dest, int off, int len)Reads ints from the current position into the specified int array,
starting from the specified offset, and increases the position by the
number of ints read.
int length = dest.length;
if (off < 0 || len < 0 || (long)len + (long)off > 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 int | get(int index)Returns an int at the specified index; the position is not changed.
|
| public final boolean | hasArray()Indicates whether this buffer is based on a int 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 + 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.
An int 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 ints from/to
bytes.
If this buffer is not based on a byte buffer, then always return the
platform's native byte order.
|
| abstract int[] | 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.IntBuffer | put(int i)Writes the given int to the current position and increases the position
by 1.
|
| public final java.nio.IntBuffer | put(int[] src)Writes ints from the given int array to the current position and
increases the position by the number of ints written.
Calling this method has the same effect as
{@code put(src, 0, src.length)}.
return put(src, 0, src.length);
|
| public java.nio.IntBuffer | put(int[] src, int off, int len)Writes ints from the given int array, starting from the specified offset,
to the current position and increases the position by the number of ints
written.
int length = src.length;
if (off < 0 || len < 0 || (long)len + (long)off > 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.IntBuffer | put(java.nio.IntBuffer src)Writes all the remaining ints of the {@code src} int buffer to this
buffer's current position, and increases both buffers' position by the
number of ints copied.
if (src == this) {
throw new IllegalArgumentException();
}
if (src.remaining() > remaining()) {
throw new BufferOverflowException();
}
int[] contents = new int[src.remaining()];
src.get(contents);
put(contents);
return this;
|
| public abstract java.nio.IntBuffer | put(int index, int i)Write a int to the specified index of this buffer; the position is not
changed.
|
| public abstract java.nio.IntBuffer | 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 represents of the state of this int 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.IntBuffer | wrap(int[] array)Creates a new int buffer by wrapping the given int 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.IntBuffer | wrap(int[] array, int start, int len)Creates a new int buffer by wrapping the given int 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)len + (long)start > array.length) {
throw new IndexOutOfBoundsException();
}
IntBuffer buf = BufferFactory.newIntBuffer(array);
buf.position = start;
buf.limit = start + len;
return buf;
