of
Creates a stack assignment that loads the default value for a given type.- Parameters:
typeDefinition
- The type for which a default value should be loaded onto the operand stack.- Returns:
- A stack manipulation loading the default value for the given type.
-
isValid
public boolean isValid()Determines if this stack manipulation is valid.- Specified by:
isValid
in interfaceStackManipulation
- Returns:
- If
false
, this manipulation cannot be applied and should throw an exception.

in interfaceStackManipulation
- Parameters:
methodVisitor
- The method visitor used to write the method implementation to.implementationContext
- The context of the current implementation.- Returns:
- The changes to the size of the operand stack that are implied by this stack manipulation.
