Class Buffer

java.lang.Object

net.beadsproject.beads.data.Buffer

All Implemented Interfaces:

java.io.Serializable

public class Buffer
extends java.lang.Object
implements java.io.Serializable

A Buffer stores a one-dimensional buffer of floats for use as a wavetable or a window. Buffer does not perform any interpolation in this version, you should just make sure your buffer is high-res enough for what you need. Could add interpolation easily if needed.

Constructor Detail

Buffer

public Buffer(int size)

Instantiates a new buffer.

Parameters:

size - the size of the buffer.

Method Detail

getValueFraction

public float getValueFraction(float fraction)

Returns the value of the buffer at the given fraction along its length (0 = start, 1 = end). Uses linear interpolation.

Parameters:

fraction - the point along the buffer to inspect.

Returns:

the value at that point.

getValueFractionNoInterp

public float getValueFractionNoInterp(float fraction)

Returns the value of the buffer at the given fraction along its length (0 = start, 1 = end). No interpolation.

Parameters:

fraction - the point along the buffer to inspect.

Returns:

the value at that point.

getValueIndex

public float getValueIndex(int index)

Returns the value of the buffer at a specific index. If index is outside the range, then it is clipped to the ends.

Parameters:

index - the index to inspect.

Returns:

the value at that point.

toString

public java.lang.String toString()

Returns the contents of the buffer as a String over one line.

Overrides:

toString in class java.lang.Object

Returns:

Buffer as String.
