AbstractValue

public AbstractValue(java.lang.String xpath)

Method Detail

getHandler

public org.xml.sax.ContentHandler getHandler()

Description copied from interface: Instruction

provides a handler to parce instruction

Specified by:

getHandler in interface Instruction

Returns:

getPath

public XmlPath getPath()

Description copied from interface: Instruction

Provides path to the instruction

Specified by:

getPath in interface Instruction

Returns:

XmlPath path
generally path can be modified outside, so it should return clone if path is statically calculated inside

childDone

public void childDone(Instruction child)

Description copied from interface: Instruction

Child notifies a parent that evaluation done, and a parent can use it for own evaluation

Specified by:

childDone in interface Instruction

setParent

public void setParent(Instruction parent)

Description copied from interface: Instruction

call back from processor to set parent instruction

Specified by:

setParent in interface Instruction

getParent

public Instruction getParent()

Description copied from interface: Instruction

returns parent, not sure that we need it at all

Specified by:

getParent in interface Instruction

Returns:

parent

getNameSpace

public Instruction.NameSpace getNameSpace()

Description copied from interface: Instruction

return current name space

Specified by:

getNameSpace in interface Instruction

Returns:

NameSpace where children can be stored makes no sense for simple variables

getAllowedAttributeNames

public java.lang.String[] getAllowedAttributeNames()

Description copied from interface: Instruction

Funtions used only for diagnostic purpose to check if not allowed attribute for instruction used.

Specified by:

getAllowedAttributeNames in interface Instruction

Returns:

String[] names of allowed attribute, can return null if any attribute is allowed
