Method Detail

slice

public FloatBuffer slice()
Description copied from class: FloatBuffer
Creates a new float buffer whose content is a shared subsequence of this buffer's content.

The content of the new buffer will start at this buffer's current position. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.

The new buffer's position will be zero, its capacity and its limit will be the number of floats remaining in this buffer, and its mark will be undefined. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.

Specified by:
slice in class FloatBuffer
Returns:
The new float buffer

duplicate

public FloatBuffer duplicate()
Description copied from class: FloatBuffer
Creates a new float buffer that shares this buffer's content.

The content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.

The new buffer's capacity, limit, position, and mark values will be identical to those of this buffer. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.

Specified by:
duplicate in class FloatBuffer
Returns:
The new float buffer

asReadOnlyBuffer

public FloatBuffer asReadOnlyBuffer()
Description copied from class: FloatBuffer
Creates a new, read-only float buffer that shares this buffer's content.

The content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer; the new buffer itself, however, will be read-only and will not allow the shared content to be modified. The two buffers' position, limit, and mark values will be independent.

The new buffer's capacity, limit, position, and mark values will be identical to those of this buffer.

If this buffer is itself read-only then this method behaves in exactly the same way as the duplicate method.

Specified by:
asReadOnlyBuffer in class FloatBuffer
Returns:
The new, read-only float buffer

ix

protected int ix(int i)

get

public float get()
Description copied from class: FloatBuffer
Relative get method. Reads the float at this buffer's current position, and then increments the position.

Specified by:
get in class FloatBuffer
Returns:
The float at the buffer's current position

get

public float get(int i)
Description copied from class: FloatBuffer
Absolute get method. Reads the float at the given index.

Specified by:
get in class FloatBuffer
Parameters:
i - The index from which the float will be read
Returns:
The float at the given index

put

public FloatBuffer put(float x)
Description copied from class: FloatBuffer
Relative put method  (optional operation).

Writes the given float into this buffer at the current position, and then increments the position.

Specified by:
put in class FloatBuffer
Parameters:
x - The float to be written
Returns:
This buffer

put

public FloatBuffer put(int i,
                       float x)
Description copied from class: FloatBuffer
Absolute put method  (optional operation).

Writes the given float into this buffer at the given index.

Specified by:
put in class FloatBuffer
Parameters:
i - The index at which the float will be written
x - The float value to be written
Returns:
This buffer

compact

public FloatBuffer compact()
Description copied from class: FloatBuffer
Compacts this buffer  (optional operation).

The floats between the buffer's current position and its limit, if any, are copied to the beginning of the buffer. That is, the float at index p = position() is copied to index zero, the float at index p + 1 is copied to index one, and so forth until the float at index limit() - 1 is copied to index n = limit() - 1 - p. The buffer's position is then set to n+1 and its limit is set to its capacity. The mark, if defined, is discarded.

The buffer's position is set to the number of floats copied, rather than to zero, so that an invocation of this method can be followed immediately by an invocation of another relative put method.

Specified by:
compact in class FloatBuffer
Returns:
This buffer

isDirect

public boolean isDirect()
Description copied from class: FloatBuffer
Tells whether or not this float buffer is direct.

Specified by:
isDirect in class FloatBuffer
Returns:
true if, and only if, this buffer is direct

isReadOnly

public boolean isReadOnly()
Description copied from class: Buffer
Tells whether or not this buffer is read-only.

Specified by:
isReadOnly in class Buffer
Returns:
true if, and only if, this buffer is read-only

order

public ByteOrder order()
Description copied from class: FloatBuffer
Retrieves this buffer's byte order.

The byte order of a float buffer created by allocation or by wrapping an existing float array is the native order of the underlying hardware. The byte order of a float buffer created as a view of a byte buffer is that of the byte buffer at the moment that the view is created.

Specified by:
order in class FloatBuffer
Returns:
This buffer's byte order
