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.

Overrides:

slice in class ByteBufferAsFloatBufferB

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.

Overrides:

duplicate in class ByteBufferAsFloatBufferB

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.

Overrides:

asReadOnlyBuffer in class ByteBufferAsFloatBufferB

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.

Overrides:

put in class ByteBufferAsFloatBufferB

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.

Overrides:

put in class ByteBufferAsFloatBufferB

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.

Overrides:

compact in class ByteBufferAsFloatBufferB

isDirect

public boolean isDirect()

Description copied from class: FloatBuffer

Tells whether or not this float buffer is direct.

Overrides:

isDirect in class ByteBufferAsFloatBufferB

isReadOnly

public boolean isReadOnly()

Description copied from class: Buffer

Tells whether or not this buffer is read-only.

Overrides:

isReadOnly in class ByteBufferAsFloatBufferB

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.

Overrides:

order in class ByteBufferAsFloatBufferB

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
