createVariable
Description copied from interface:VariableResolverFactory
Creates a new variable. This probably doesn't need to be implemented in most scenarios. This is used for variable assignment.- Specified by:
createVariable
in interfaceVariableResolverFactory
- Overrides:
createVariable
in classMapVariableResolverFactory
- Parameters:
name
- - name of the variable being createdvalue
- - value of the variable- Returns:
- instance of the variable resolver associated with the variable
-
createVariable
Description copied from interface:VariableResolverFactory
Creates a new variable, and assigns a static type. It is expected the underlying factory and resolver will enforce this.- Specified by:
createVariable
in interfaceVariableResolverFactory
- Overrides:
createVariable
in classMapVariableResolverFactory
- Parameters:
name
- - name of the variable being createdvalue
- - value of the variabletype
- - the static type- Returns:
- instance of the variable resolver associated with the variable
-
getVariableResolver
Description copied from interface:VariableResolverFactory
Return a variable resolver for the specified variable name. This method is expected to traverse the heirarchy of ResolverFactories.- Specified by:
getVariableResolver
in interfaceVariableResolverFactory
- Overrides:
getVariableResolver
in classMapVariableResolverFactory
- Parameters:
name
- - variable name- Returns:
- - instance of the VariableResolver for the specified variable
-
isTarget
Description copied from interface:VariableResolverFactory
Deterimines whether or not the current VariableResolverFactory is the physical target for the actual variable.- Specified by:
isTarget
in interfaceVariableResolverFactory
- Overrides:
isTarget
in classMapVariableResolverFactory
- Parameters:
name
- - variable name- Returns:
- - boolean indicating whether or not factory is the physical target
-
isResolveable
Description copied from interface:VariableResolverFactory
Determines whether or not the variable is resolver in the chain of factories.- Specified by:
isResolveable
in interfaceVariableResolverFactory
- Overrides:
isResolveable
in classMapVariableResolverFactory
- Parameters:
name
- - variable name- Returns:
- - boolean
-
isIndexedFactory
public boolean isIndexedFactory()- Specified by:
isIndexedFactory
in interfaceVariableResolverFactory
- Overrides:
isIndexedFactory
in classBaseVariableResolverFactory
