Method Detail

singleVariableIterationName

public static String singleVariableIterationName(String selectionName)

Calculates the default name for the single variable in the selection with the given name.

over

public static IterationBuilderOver over(Class<? extends org.jboss.windup.graph.model.WindupVertexFrame> sourceType,
                                        String source)

Begin an Iteration over the named selection of the given type. Also sets the name and type of the variable for this iteration's "current element". The type serves for automatic type check.

over

public static IterationBuilderOver over(String source)

Begin an Iteration over the named selection. Also sets the name of the variable for this iteration's "current element".

public static IterationBuilderOver over(Class<? extends org.jboss.windup.graph.model.WindupVertexFrame> sourceType)

Begin an Iteration over the selection of the given type, named with the default name. Also sets the name of the variable for this iteration's "current element" to have the default value.

over

public static IterationBuilderOver over()

Begin an Iteration over the selection that is placed on the top of the Variables. Also sets the name of the variable for this iteration's "current element" (i.e payload) to have the default value.

getRequiredParameterNames

public Set<String> getRequiredParameterNames()

These are really just needed to pass through to the condition, since the visitor system doesn't expect operations to have conditions and wouldn't otherwise find them.
