getName

public String getName()

Description copied from class: Facet

Returns the name of this Facet

Specified by:

getName in class Facet

Returns:

the name of this Facet

getValue

public String getValue()

Description copied from class: Facet

public void setValue(String value)
              throws SchemaException

Throws:

SchemaException

setDoNotMerge

public void setDoNotMerge(boolean dont)

isDoNotMerge

public boolean isDoNotMerge()

addBranch

public void addBranch(String pat)

Add a branch to a pattern: that is, combine this pattern with another, so that the resulting pattern is the "or" of the two patterns

Parameters:

pat - the new branch, which must be a valid regular expression

checkFacetRestriction

public void checkFacetRestriction(UserSimpleType type,
                                  SimpleType base,
                                  SchemaCompiler compiler)
                           throws SchemaException

Check that this facet is legal when used on a type derived by restriction

Overrides:

checkFacetRestriction in class Facet

Parameters:

base - the type from which the restricted type is derived

compiler -

type - the type on which the facet is defined

Throws:

SchemaException - if the facet is not legal

testAtomicValue

public boolean testAtomicValue(AtomicValue value)

Test whether an atomic value conforms to this facet

Specified by:

testAtomicValue in class Facet

Parameters:

value - the value to be tested

Returns:

true if the value conforms; false if it doesn't conform, or if the test fails
