FloatBuffer

Creates a float buffer based on a newly allocated float array.

Returns the array that backs this buffer (optional operation). The returned value is the actual array, not a copy, so modifications to the array write through to the buffer.

Subclasses should override this method with a covariant return type to provide the exact type of the array.

Use hasArray to ensure this method won't throw. (A separate call to isReadOnly is not necessary.)

Returns the offset into the array returned by array of the first element of the buffer (optional operation). The backing array (if there is one) is not necessarily the same size as the buffer, and position 0 in the buffer is not necessarily the 0th element in the array. Use buffer.array()[offset + buffer.arrayOffset() to access element offset in buffer.

Use hasArray to ensure this method won't throw. (A separate call to isReadOnly is not necessary.)

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.

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 remaining(); the limit is set to capacity; the mark is cleared.

Compare the remaining floats of this buffer to another float buffer's remaining floats.

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 buffers' position, limit and mark are independent.

Checks whether this float buffer is equal to another object. If other is not a FloatBuffer then false is returned.

Two float buffers are equal if their remaining floats are equal. Position, limit, capacity and mark are not considered.

This method considers two floats a and b to be equal if a == b or if a and b are both NaN. Unlike equals(Object), this method considers -0.0 and +0.0 to be equal.

Returns a float at the specified index; the position is not changed.

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.

Returns the float at the current position and increases the position by 1.

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 get(dst, 0, dst.length).

Returns true if array and arrayOffset won't throw. This method does not return true for buffers not backed by arrays because the other methods would throw UnsupportedOperationException, nor does it return true for buffers backed by read-only arrays, because the other methods would throw ReadOnlyBufferException.

Calculates this buffer's hash code from the remaining chars. The position, limit, capacity and mark don't affect the hash code.

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.

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.

Writes a float to the specified index of this buffer; the position is not changed.

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.

Writes all the remaining floats of the src float buffer to this buffer's current position, and increases both buffers' position by the number of floats copied.

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 put(src, 0, src.length).

Writes the given float to the current position and increases the position by 1.

Returns a sliced buffer that shares its content with this buffer.

The sliced buffer's capacity will be this buffer's 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 buffers' position, limit and mark are independent.

Creates a new float buffer by wrapping the given float array.

Calling this method has the same effect as wrap(array, 0, array.length).

Creates a new float buffer by wrapping the given float array.

The new buffer's position will be start, limit will be start + floatCount, capacity will be the length of the array.
