Method Detail

getValue

Object getValue(String str,
                ValidationContext vc)

Specified by:

getValue in class DatatypeBase

lexicallyAllows

boolean lexicallyAllows(String str)

Specified by:

lexicallyAllows in class DatatypeBase

allowsValue

boolean allowsValue(String str,
                    ValidationContext vc)

Overrides:

allowsValue in class DatatypeBase

getMeasure

Measure getMeasure()

Overrides:

getMeasure in class DatatypeBase

getLength

public int getLength(Object obj)

Specified by:

getLength in interface Measure

isContextDependent

public boolean isContextDependent()

Description copied from interface: Datatype

Checks if this datatype may need a context object for the validation.

The callee must return true even when the context is not always necessary. (For example, the "QName" type doesn't need a context object when validating unprefixed string. But nonetheless QName must return true.)

XSD's string and short types are examples of context-independent datatypes. Its QName and ENTITY types are examples of context-dependent datatypes.

When a datatype is context-independent, then the Datatype.isValid(java.lang.String, org.relaxng.datatype.ValidationContext) method, the Datatype.checkValid(java.lang.String, org.relaxng.datatype.ValidationContext) method, the Datatype.createStreamingValidator(org.relaxng.datatype.ValidationContext) method and the Datatype.createValue(java.lang.String, org.relaxng.datatype.ValidationContext) method can be called without providing a context object.

Specified by:

isContextDependent in interface Datatype

Overrides:

isContextDependent in class DatatypeBase

Returns:

true if this datatype is context-dependent (it needs a context object sometimes); false if this datatype is context-independent (it never needs a context object).

getIdType

public int getIdType()

Description copied from interface: Datatype

Checks if the ID/IDREF semantics is associated with this datatype.

This method is introduced to support the RELAX NG DTD compatibility spec. (Of course it's always free to use this method for other purposes.)

If you are implementing a datatype library and have no idea about the "RELAX NG DTD compatibility" thing, just return ID_TYPE_NULL is fine.

Specified by:

getIdType in interface Datatype

Overrides:

getIdType in class DatatypeBase

Returns:

If this datatype doesn't have any ID/IDREF semantics, it returns Datatype.ID_TYPE_NULL. If it has such a semantics (for example, XSD:ID, XSD:IDREF and comp:ID type), then it returns Datatype.ID_TYPE_ID, Datatype.ID_TYPE_IDREF or Datatype.ID_TYPE_IDREFS.

valueHashCode

public int valueHashCode(Object obj)

Description copied from interface: Datatype

Computes the hash code for a value object, which is consistent with the sameValue method.

Specified by:

valueHashCode in interface Datatype

Overrides:

valueHashCode in class DatatypeBase

Returns:

hash code for the specified value object.

sameValue

public boolean sameValue(Object obj1,
                         Object obj2)

Description copied from interface: Datatype

Tests the equality of two value objects which were originally created by the createValue method of this object. The behavior is undefined if objects not created by this type are passed. It is the caller's responsibility to ensure that value objects belong to this type.

Specified by:

sameValue in interface Datatype

Overrides:

sameValue in class DatatypeBase

Returns:

true if two value objects are considered equal according to the definition of this datatype; false if otherwise.
