Class ProcessorImpl

java.lang.Object
  fr.ove.openmath.jome.model.processor.ProcessorImpl

All Implemented Interfaces:

Processor

Direct Known Subclasses:

DepthProcessor, WidthDepthProcessor, WidthProcessor

public class ProcessorImpl

extends java.lang.Object

implements Processor

An implementation of a @see Processor.
The method doProcess does nothing. Subclasses have to, at least, override it to provide the desired processing.

Field Detail

COMPUTE

public static final int COMPUTE

Compute the the necessaru stuff for the iconifcation of the formula.

See Also:

Constant Field Values

SIMPLE_ICONIFICATION

public static final int SIMPLE_ICONIFICATION

Iconify the formula according to the iconification level fixed.
We assume the necessary computation for the iconification of the formula was previously done.
This is a simple iconification process. Subtrees of iconfied ones are not iconified.

See Also:

Constant Field Values

RECURSIVE_ICONIFICATION

public static final int RECURSIVE_ICONIFICATION

Iconify the formula according to the iconification level fixed.
We assume the necessary computation for the iconification of the formula was previously done.
This is a recursive iconification process. Subtrees of iconfied ones are also iconified.

See Also:

Constant Field Values

COMPUTE_AND_ICONIFY

public static final int COMPUTE_AND_ICONIFY

Compute and iconify (recursivly) the formula according to the iconification level fixed.
This is the default behaviour.

updateDisplay - true if the display needs update. false otherwise.

getUpdateDisplay

public boolean getUpdateDisplay()

Checks if, after processing the formula, the display has to be updated.

Specified by:

getUpdateDisplay in interface Processor

init

public void init()

Initialisation of the processor. !! Method to override by subclasses !! The default is just setting the processing Id to be COMPUTE_AND_ICONIFY;

Specified by:

init in interface Processor

Specified by:

setLevel in interface Processor

Parameters:

level - the level.

getLevel

public int getLevel()

Returns the level from which the processing starts.

Specified by:

getLevel in interface Processor
