Method Details

isEmptiable

public boolean isEmptiable()
                    throws MissingComponentException

Determine if empty content is allowed

Specified by:

isEmptiable in class ModelGroup

Returns:

Throws:

MissingComponentException - if the schema contains unresolved references to required components

isPointless

public boolean isPointless(ModelGroup container)

Test whether the compositor is pointless, as described in XML Schema Part 1 Schema Component Constraint: Particle Valid (Restriction)

Overrides:

isPointless in class ModelGroup

Parameters:

container - not used

Returns:

true if the particle is pointless (which effectively means it can't match anything)

validate

public boolean validate(SchemaCompiler compiler)
                 throws SchemaException

Checks the validity of this Compositor definition.

Specified by:

validate in interface UserSchemaComponent

Overrides:

validate in class ModelGroup

Parameters:

compiler - the schema compiler

Returns:

true when this Schema definition is valid, otherwise false.

Throws:

SchemaException - when the error listener decides an error is fatal

getCompositorName

public String getCompositorName()

Get the name of this compositor

Specified by:

getCompositorName in class ModelGroup

Returns:

one of "sequence", "choice", or "all"
