GridData

public GridData(float[] array,
 GridInfo gridInfo)

Method Details

getData

public float[] getData()

getGridInfo

public GridInfo getGridInfo()

initGridData

public int initGridData(float[] array,
 GridInfo gridInfo)

show

public void show(double ge)

show

public void show(double ge,
 PrintStream out)

getValueAt

public double getValueAt(int x,
 int y)

return the value at the position x,y

setValueAt

public int setValueAt(int x,
 int y,
 float value)

Sets the value at position x,y

Parameters:

x -

y -

value -

Returns:

0 if there is no error, otherwise -1

setValueAt

public int setValueAt(int x,
 int y,
 double value)

Sets the value at position x,y

Parameters:

x -

y -

value -

Returns:

0 if there is no error, otherwise -1

updateStatistics

public int updateStatistics()

roundValues

public int roundValues(int precision)

public int roundValues(int precision) Rounds off values in the data array to the decimal precision given. This reduces the number of unique values in the array, resulting in more effective data compression when we use the ZLIB deflate method.

Parameters:

precision - Number of decimal places of precision: 0 rounds to whole numbers 1 to tenths, etc.

Returns:

Status: 0 indicates success

getNumberMissing

public int getNumberMissing()

Returns:

setData

public void setData(float[] data)

initGridInfo

public void initGridInfo(GridInfo gridInfo)
