Method Detail

marshal

public Streamable marshal(MacroDefinition macroDefinition,
                          ConversionContext conversionContext)
                   throws XhtmlException

Marshals the supplied MacroDefinition using either V1 or V2 macro storage format. Will use V2 storage format in preference, but only if it can find metadata for the macro.

If the MacroDefinition originated in V1 format, but is being marshalled as V2, then a flag will be set in the ConversionContext to record that the fact that the macro is being migrated from one storage format to another. This information is then later retrieved via the wasMigrationPerformed(com.atlassian.confluence.content.render.xhtml.ConversionContext) method.

Specified by:

marshal in interface Marshaller<MacroDefinition>

Parameters:

macroDefinition - The macro to be migrated

conversionContext - the conversion context in which to store the migration flag

Returns:

A Streamable containing the marshalled macro defintion.

Throws:

XhtmlException - if an error occurs during marshalling

wasMigrationPerformed

public boolean wasMigrationPerformed(ConversionContext conversionContext)

Description copied from interface: MigrationAware

Given a ConversionContext that was previously used to perform a migration, determine if that context contains information that indicates whether a "migration" was performed. What constitutes a migration is implementation-dependent.

Specified by:

wasMigrationPerformed in interface MigrationAware

Parameters:

conversionContext - the context used for the migration

Returns:

true if the supplied ConversionContext contains the flag that indicates that a macro storage format migration was performed within that context, false otherwise.
