Classes and Interfaces
CountingLineProcessor	Processes only a certain number of lines.
LineProcessorBase	Abstract base class for line processors associated with tuplizer or other class that processes instances of MaprptLine, used mostly to support pragmas.
MatchingLineProcessor	Processes lines whose first characters match a prescribed set of characters.

Class: CountingLineProcessor   next package

Processes only a certain number of lines.
Treat this class as "thread-hostile", since it is designed to be created, used and discarded by a single thread.

Constructors

Public ctor for initializing an instance of this class. Parameters: anExpectedFirstCharset - maximum number of lines to be processed. public CountingLineProcessor(int aMaximumLineCount)

Methods

public boolean wantLine(com.arsi.mj.maprpt.parser.line.types.MaprptLine aMaprptLine)

Class: LineProcessorBase   previous next package

Abstract base class for line processors associated with tuplizer or other class that processes instances of MaprptLine, used mostly to support pragmas.
Treat this class as "thread-hostile", as it contains no synchronization and should be created, used and discarded by a single thread.

Constructors

public LineProcessorBase()

Methods

Add processing action to this line processor. Parameters: anAction - the processing action to add. public void addAction(com.arsi.mj.maprpt.parser.lineproc.LineProcessorBase.IAction anAction)

Apply actions that have been registered with this line processor to the specified Mapper report line. The calling convention is to invoke only after wantLine indicates that the line processor is interested in the line. Parameters: aMaprptLine - a typed line (e.g., AsteriskLine, PeriodLine, etc.) from a Mapper report. Returns: true to continue next stage of processing on line, false to stop processing of the line after this method returns; if a line processor "eats" a line such that the caller should not process the line, this method should return false. public boolean applyActions(com.arsi.mj.maprpt.parser.line.types.MaprptLine aMaprptLine)

Remove processing action from this line processor. Parameters: anAction - the processing action to remove. public void removeAction(com.arsi.mj.maprpt.parser.lineproc.LineProcessorBase.IAction anAction)

Is line wanted by this line processor? If line is wanted, it should be passed to applyActions for processing. If line is not wanted, no more calls should be made to this line processor instance (treat as an end-of-file indicator). IMPORTANT! Since derived classes may implement counting algorithms based on calls to this method, the caller should invoke this method only once per line. Parameters: aMaprptLine - a typed line (e.g., AsteriskLine, PeriodLine, etc.) from a Mapper report. Returns: true if line is wanted by line processor, false if line is not wanted. public abstract boolean wantLine(com.arsi.mj.maprpt.parser.line.types.MaprptLine aMaprptLine)
