Constructor Detail

AttributeDecl

public AttributeDecl(Schema schema, String name)
Creates a new AttrDecl with the given name

Parameters: name of the Attribute defined by this attribute declaration schema the schema that contains the new attrDecl

AttributeDecl

public AttributeDecl(Schema schema)
Creates a new AttrDecl in the given schema.

Parameters: schema the schema that contains the new attrDecl

Method Detail

getDefaultValue

public String getDefaultValue()
Returns the default value of this element definition.

Returns: the default value of this element definition, or null if no default was specified.

getFixedValue

public String getFixedValue()
Returns the fixed value of this element definition.

Returns: the fixed value of this element definition, or null if no default was specified.

getForm

public Form getForm()
Returns the Form for this attribute declaration. The Form object species whether or not names are qualified or unqualified for instances of this attribute declaration. If null, the Form should be obtained from the parent Schema.

Returns: the Form for this attribute declaration, or null if not set.

getId

public String getId()
Returns the Id for this attribute declaration

Returns: the Id for this attribute declaration

getName

public String getName()
Returns the name of attributes defined by this AttributeDecl. If this AttributeDecl is a reference to another AttributeDecl, the reference will be resolved and the name of the referenced AttributeDecl will be returned. The name will always be an NCName, no namespace prefix will be included.

Returns: the name of attributes defined by this AttributeDecl.

getName

public String getName(boolean ignoreRef)
Returns the name of this Attribute declaration. The name will always be an NCName, no namespace prefix will be included.

Parameters: ingoreRef a boolean that when false, indicates that if this is an attribute reference to return the reference name. Otherwise the only the local name is used.

Returns: the name of this attribute declaration

getParent

public Structure getParent()
Returns the parent of this AttributeDecl, this value may be null if no parent has been set.

Returns: the parent Structure of this AttributeDecl.

getReference

public AttributeDecl getReference()
Returns the AttributeDecl that this attribute definition references. This will return null if this attribute definition does not reference a different attribute definition.

Returns: the AttributeDecl that this attribute definition references

getReferenceName

public String getReferenceName()
Returns the actual reference name of this AttributeDecl, or null if this AttributeDecl is not a reference. The name returned, if not null, will be a QName, possibly containing the namespace prefix.

Returns: the reference name

getSchema

public Schema getSchema()
Returns the Schema that this AttributeGroupDecl belongs to.

Returns: the Schema that this AttributeGroupDecl belongs to.

getSimpleType

Returns: the data type associated with this AttributeDecl.

getStructureType

public short getStructureType()
Returns the type of this Schema Structure

Returns: the type of this Schema Structure

getUse

public String getUse()
Returns the value of the use attribute for this attribute declaration or attribute reference. If this is a reference the value of the use attribute will *not* be obtained from the referenced attribute declaration as top-level attributes do not take into account the use attribute.
