Method Detail

createVariable

public VariableResolver createVariable(String name,
                              Object value)

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 interface VariableResolverFactory

Overrides:

createVariable in class MapVariableResolverFactory

Parameters:

name - - name of the variable being created

value - - value of the variable

Returns:

instance of the variable resolver associated with the variable

createVariable

public VariableResolver createVariable(String name,
                              Object value,
                              Class<?> type)

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 interface VariableResolverFactory

Overrides:

createVariable in class MapVariableResolverFactory

Parameters:

name - - name of the variable being created

value - - value of the variable

type - - the static type

Returns:

instance of the variable resolver associated with the variable

getVariableResolver

public VariableResolver getVariableResolver(String name)

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 interface VariableResolverFactory

Overrides:

getVariableResolver in class MapVariableResolverFactory

Parameters:

name - - variable name

Returns:

- instance of the VariableResolver for the specified variable

isTarget

public boolean isTarget(String name)

Description copied from interface: VariableResolverFactory

Deterimines whether or not the current VariableResolverFactory is the physical target for the actual variable.

Specified by:

isTarget in interface VariableResolverFactory

Overrides:

isTarget in class MapVariableResolverFactory

Parameters:

name - - variable name

Returns:

- boolean indicating whether or not factory is the physical target

isResolveable

public boolean isResolveable(String name)

Description copied from interface: VariableResolverFactory

Determines whether or not the variable is resolver in the chain of factories.

Specified by:

isResolveable in interface VariableResolverFactory

Overrides:

isResolveable in class MapVariableResolverFactory

Parameters:

name - - variable name

Returns:

- boolean

isIndexedFactory

public boolean isIndexedFactory()

Specified by:

isIndexedFactory in interface VariableResolverFactory

Overrides:

isIndexedFactory in class BaseVariableResolverFactory
