XSLVariable

public XSLVariable()

Method Detail

prepareAttributes

public void prepareAttributes()
                       throws TransformerConfigurationException

Description copied from class: StyleElement

Set the attribute list for the element. This is called to process the attributes (note the distinction from processAttributes in the superclass). Must be supplied in a subclass

Overrides:

prepareAttributes in class XSLGeneralVariable

Throws:

TransformerConfigurationException

isInstruction

public boolean isInstruction()

Determine whether this node is an instruction.

Overrides:

isInstruction in class XSLVariableDeclaration

Returns:

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

getRequiredType

public SequenceType getRequiredType()

Get the static type of the variable. This is the declared type, unless the value is statically known and constant, in which case it is the actual type of the value.

Specified by:

getRequiredType in class XSLVariableDeclaration

compile

public Instruction compile()
                    throws TransformerConfigurationException

Compile: this ensures space is available for local variables declared within this global variable

Specified by:

compile in class StyleElement

Returns:

either an Instruction, or null (indicating a no-op).

Throws:

TransformerConfigurationException
