Constructor Detail

XSLVariable

public XSLVariable()

Method Detail

getSlotNumber

public int getSlotNumber()

Description copied from interface: Binding

Determine a slot number for the variable.

Specified by:

getSlotNumber in interface Binding

isInstruction

public boolean isInstruction()

Determine whether this node is an instruction.

Overrides:

isInstruction in class StyleElement

Returns:

true - it is an instruction (well, it can be, anyway)

validate

public void validate()
              throws TransformerConfigurationException

Check that the variable is not already declared, and allocate a slot number

Overrides:

validate in class XSLGeneralVariable

Throws:

TransformerConfigurationException

getDataType

public int getDataType()

Get the data type, if known statically.

Specified by:

getDataType in interface Binding

Returns:

the data type if known

constantValue

public Value constantValue()

Get the value, if known statically.

Specified by:

constantValue in interface Binding

Returns:

the value if known in advance, or null if not.

process

public void process(Context context)
             throws TransformerException

Process the variable declaration

Specified by:

process in class StyleElement

Parameters:

context - The context in the source XML document, giving access to the current node, the current variables, etc.

Throws:

TransformerException
