PatternFacet(Configuration config) Create a pattern facet

Method Summary

Modifier and Type	Method and Description
void	addBranch(java.lang.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
void	checkFacetRestriction(UserSimpleType type, SimpleType base, SchemaCompiler compiler) Check that this facet is legal when used on a type derived by restriction
void	compile(java.util.List<java.lang.String> warnings) Compile the regular expression
Function	getFacetAsFunctionItem() Get a function item that represents this Facet schema component.
java.lang.String	getFlags() Get the flags for the regular expression
java.lang.String	getName() Returns the name of this Facet
RegularExpression	getRegularExpression()
java.lang.String	getValue() Returns the lexical representation of the value of this facet
boolean	isDoNotMerge()
void	setDoNotMerge(boolean dont)
void	setFlags(java.lang.String flags) Saxon allows flags for the regular expression (e.g.
void	setValue(java.lang.String value)
boolean	testAtomicValue(AtomicValue value) Test whether an atomic value conforms to this facet

Constructor Detail

PatternFacet

public PatternFacet(Configuration config)

Create a pattern facet

Parameters:

config - the Saxon configuration

Method Detail

getName

public java.lang.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 java.lang.String getValue()

Description copied from class: Facet

Returns the lexical representation of the value of this facet

Specified by:

getValue in class Facet

Returns:

the value of this facet, as a string

getRegularExpression

public RegularExpression getRegularExpression()

setValue

public void setValue(java.lang.String value)

setFlags

public void setFlags(java.lang.String flags)

Saxon allows flags for the regular expression (e.g. "i" meaning case-independent) to be set using the saxon:flags attribute

Parameters:

flags - the regular expression flags

getFlags

public java.lang.String getFlags()

Get the flags for the regular expression

Returns:

the flags

compile

public void compile(java.util.List<java.lang.String> warnings)
             throws SchemaException

Compile the regular expression

Parameters:

warnings - if non-null, receives any warnings that arise from compiling the regular expression

Throws:

SchemaException - if the regular expression is invalid

setDoNotMerge

public void setDoNotMerge(boolean dont)

isDoNotMerge

public boolean isDoNotMerge()

addBranch

public void addBranch(java.lang.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)

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 - the schema compiler

type - the type on which the facet is defined

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

getFacetAsFunctionItem

public Function getFacetAsFunctionItem()

Description copied from class: Facet

Get a function item that represents this Facet schema component.

Specified by:

getFacetAsFunctionItem in class Facet
