Constructor Detail

AttributeCreator

public AttributeCreator()

Method Detail

setSchemaType

public void setSchemaType(SimpleType type)

Set the required schema type of the attribute

Parameters:

type - the required schema type, if validation against a specific type is required, or null if no validation is required

getSchemaType

public SimpleType getSchemaType()

Return the required schema type of the attribute

Specified by:

getSchemaType in interface ValidatingInstruction

Returns:

if validation against a schema type was requested, return the schema type (always a simple type). Otherwise, if validation against a specific type was not requested, return null

setValidationAction

public void setValidationAction(int action)

Set the validation action required

Parameters:

action - the validation action required, for example strict or lax

getValidationAction

public int getValidationAction()

Get the validation action requested

Specified by:

getValidationAction in interface ValidatingInstruction

Returns:

the validation action, for example strict or lax

setOptions

public void setOptions(int options)

Set the options to be used on the attribute event

Parameters:

options - Options to be used. The only option currently defined is ReceiverOptions.REJECT_DUPLICATES, which controls whether or not it is an error to create two attributes with the same name for the same element. (This is an error in XQuery but not in XSLT).

setRejectDuplicates

public void setRejectDuplicates()

Indicate that two attributes with the same name are not acceptable. (This option is set in XQuery, but not in XSLT)

setNoSpecialChars

public void setNoSpecialChars()

Indicate that the attribute value contains no special characters that might need escaping

getOptions

public int getOptions()

Get the options to be used on the attribute event

Returns:

the option flags to be used

computeSpecialProperties

public int computeSpecialProperties()

Get the static properties of this expression (other than its type). The result is bit-signficant. These properties are used for optimizations. In general, if property bit is set, it is true, but if it is unset, the value is unknown.

Overrides:

computeSpecialProperties in class SimpleNodeConstructor

Returns:

a set of flags indicating static properties of this expression

processValue

public final void processValue(CharSequence value,
                               XPathContext context)
                        throws XPathException

Process the value of the node, to create the new node.

Specified by:

processValue in class SimpleNodeConstructor

Parameters:

value - the string value of the new node

context - the dynamic evaluation context

Throws:

XPathException
