Description:

a helper class for fileIn - keeps track of class and category to filein for.
Instances of this are created by the #methodsFor: methods in Class, to
read the next chunk(s) from a stream.

ClassCategoryReaders allow different ways of keeping the sourceCode of its
loaded code. This is controlled by the SourceMode class variable which may be:

    #discard         - forget the source code; no browsing/recompilation is possible

    #keep            - keep the source code as a string.
                       any saved image will later be fully independent of any
                       source files.

    #reference       - keep a reference to the loaded files basename
                       In order to be browsable, the original sourcefile should be
                       found along the sourcePath
                       (i.e. typically a link in the source directory should be present)

    #absReference    - keep a reference to the loaded files absolute pathname
                       but only if the file ends with .st.
                       (this is ok in multiUser configurations, where all sourcefiles are mounted
                       on a common path; typically automounted systems)

    #forceAbsReference
                     - like above, but also do it for files not ending with .st.
                       Must be used with care - NEVER ever reference sources from the changes
                       file, because the changesBrowser does not adjust methods sources
                       when it compresses or removes changes.

    #sourceReference - append source to the `st.src' file,
                       and keep a reference to that file.
                       if the image is later moved to another location,
                       this file should be moved along with it.

Class protocol:

 keepSource

 keepSource: aBoolean

 skipUnchangedMethods

return true, if the default for unchanged methods is to skip them.
The default is true.

 skipUnchangedMethods: aBoolean

return true, if the default for unchanged methods is to skip them.
The default is true. Can be temporarily changed to false, if
a forced fileIn is required.

 sourceMode

return the sourceMode, which controls how sources are to be handled.
Read #documentation for more info

 sourceMode: aSymbol

set the sourceMode, which controls how sources are to be handled.

 initialize

ClassCategoryReader initialize

 class: aClass

return a new ClassCategoryReader to operate on aClass

 class: aClass category: aCategory

return a new ClassCategoryReader to read methods for aClass with
methodCategory aCategory

 class: aClass primitiveSpec: which

return a ClassCategoryReader to read a primitiveSpec chunk

Instance protocol:

 fileInFrom: aStream

read method-chunks from the input stream, aStream; compile them
and add the methods to the class defined by the class-instance var

 fileInFrom: aStream notifying: requestor passChunk: passChunk

read method-chunks from the input stream, aStream; compile them
and add the methods to the class defined by the class-instance var;
errors and notifications are passed to requestor.
If passChunk is true, chunks are given to the requestor,
via a #source: message, allowing it to open a view showing any
erroneous source code.

 fileInFrom: aStream notifying: requestor passChunk: passChunk single: oneChunkOnly

read method-chunks from the input stream, aStream; compile them
and add the methods to the class defined by the class-instance var;
errors and notifications are passed to requestor.
If passChunk is true, chunks are given to the requestor,
via a #source: message, allowing it to open a view showing any
erroneous source code.
If oneChunkOnly is true, the fileIn is finished after the first chunk.

 fileInFrom: aStream notifying: requestor passChunk: passChunk single: oneChunkOnly silent: beSilent

read method-chunks from the input stream, aStream; compile them
and add the methods to the class defined by the class-instance var;
errors and notifications are passed to requestor.
If passChunk is true, chunks are given to the requestor,
via a #source: message, allowing it to open a view showing any
erroneous source code.
If oneChunkOnly is true, the fileIn is finished after the first chunk.
The beSilent argument controls output to the transcript, if it's true or
false. If it's nil, output is controlled by the Smalltalk>>silenLoading setting.

 fileInFrom: aStream silent: beSilent

read method-chunks from the input stream, aStream; compile them
and add the methods to the class defined by the class-instance var.
The beSilent argument controls if a message is to be sent to the Transcript.
