Method Detail

getField

public ListingField getField(ProxyObj<?> proxy,
                             int varWidth)

Returns the FactoryField for the given object at index index.

Specified by:

getField in class FieldFactory

Parameters:

varWidth - the amount of variable width spacing for any fields before this one.

proxy - the object whose properties should be displayed.

Returns:

the newly generated FactoryField that shows some property or information about the given object.

getFieldLocation

public FieldLocation getFieldLocation(ListingField lf,
                                      java.math.BigInteger index,
                                      int fieldNum,

Description copied from class: FieldFactory

Return a FieldLocation that corresponds to the given index, fieldNum, and ProgramLocation IF and ONLY IF the given programLocation is the type generated by this class's FieldFactory.getFieldLocation(ListingField, BigInteger, int, ProgramLocation). Each FieldFactory should generate and process a unique ProgramLocation class.

Specified by:

getFieldLocation in class FieldFactory

Parameters:

lf - the ListingField at the current cursor.

index - the line index (corresponds to an address)

fieldNum - the index of field within the layout to try and get a FieldLocation.

programLoc - the ProgramLocation to be converted into a FieldLocation.

acceptsType

public boolean acceptsType(int category,
                           java.lang.Class<?> proxyObjectClass)

Description copied from class: FieldFactory

Used to specify which format models this field can belong to.

Specified by:

acceptsType in class FieldFactory

Parameters:

category - the category for this field

proxyObjectClass - the type of proxy object used by this field

Returns:

true if this class accepts the given category.
