+----iicm.vrml.pwutils.FloatArray
- public class FloatArray
- extends Object
FloatArray - dynamic array of float type values
better time and memory efficiency than Vector,
float[] accessible in native code

-
FloatArray()
- create with default length
-
FloatArray(float[])
- copy initial data from another float[].
-
FloatArray(FloatArray)
- copy initial data from another FloatArray (non-null).
-
FloatArray(int)
- create with initial buffer length
-
append(float)
- append one float element
-
clearData()
- clear the array
-
getCount()
- get count of used array members.
-
getData()
- get data array.
-
setData(float[])
- copy data from a float[]
-
setData(float[], int)
- copy first n elements of a float[]
-
setData(FloatArray)
- copy data from another FloatArray
-
setSize(int)
- set number of used array elements (ensures there is enough storage)
FloatArray
public FloatArray()
- create with default length
FloatArray
public FloatArray(int len)
- create with initial buffer length
FloatArray
public FloatArray(float dat[])
- copy initial data from another float[]. To say it again:
values in float[] are *copied* and not just referenced by this class
FloatArray
public FloatArray(FloatArray dat)
- copy initial data from another FloatArray (non-null).
do not use the above constructor in this case, as it would use all values,
not just the used length (count); again: values are *copied*
setData
public void setData(FloatArray dat)
- copy data from another FloatArray
setData
public void setData(float dat[])
- copy data from a float[]
setData
public synchronized void setData(float dat[],
int n)
- copy first n elements of a float[]
getCount
public final synchronized int getCount()
- get count of used array members.
Note: may be smaller than data_.length
getData
public final synchronized float[] getData()
- get data array. Only elements 0 to (getCount () - 1) were set by user.
Subsequent calls (after enlargement) may return a different array object
append
public synchronized void append(float d)
- append one float element
setSize
public synchronized void setSize(int n)
- set number of used array elements (ensures there is enough storage)
clearData
public synchronized boolean clearData()
- clear the array
- Returns:
- true if the array was previously non-empty
