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

setIndexedVariableNames

public void setIndexedVariableNames(String[] indexedVariableNames)

Overrides:

setIndexedVariableNames in class BaseVariableResolverFactory

getIndexedVariableNames

public String[] getIndexedVariableNames()

Overrides:

getIndexedVariableNames in class BaseVariableResolverFactory

createIndexedVariable

public VariableResolver createIndexedVariable(int index,
                                              String name,
                                              Object value,
                                              Class<?> type)

Specified by:

createIndexedVariable in interface VariableResolverFactory

Overrides:

createIndexedVariable in class BaseVariableResolverFactory

createIndexedVariable

public VariableResolver createIndexedVariable(int index,
                                              String name,
                                              Object value)

Specified by:

createIndexedVariable in interface VariableResolverFactory

Overrides:

createIndexedVariable in class BaseVariableResolverFactory

getIndexedVariableResolver

public VariableResolver getIndexedVariableResolver(int index)

Specified by:

getIndexedVariableResolver in interface VariableResolverFactory

Overrides:

getIndexedVariableResolver in class BaseVariableResolverFactory

setIndexedVariableResolver

public VariableResolver setIndexedVariableResolver(int index,
                                                   VariableResolver resolver)

Specified by:

setIndexedVariableResolver in interface VariableResolverFactory

Overrides:

setIndexedVariableResolver in class BaseVariableResolverFactory

variableIndexOf

public int variableIndexOf(String name)

Specified by:

variableIndexOf in interface VariableResolverFactory

Overrides:

variableIndexOf in class BaseVariableResolverFactory

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
