XSLGeneralVariable
public XSLGeneralVariable()
mayContainTemplateBody
public boolean mayContainTemplateBody()
- Determine whether this type of element is allowed to contain a template-body
- Overrides:
mayContainTemplateBody
in class StyleElement
- Returns:
- true: yes, it may contain a template-body
isGlobal
public boolean isGlobal()
isAssignable
public boolean isAssignable()
- Test whether it is permitted to assign to the variable using the saxon:assign
extension element. This will only be true if the extra attribute saxon:assignable="yes"
is present.
getOwningProcedure
public Procedure getOwningProcedure()
throws javax.xml.transform.TransformerConfigurationException
- Get the owning Procedure definition, if this is a local variable
preprocess
public void preprocess()
throws javax.xml.transform.TransformerConfigurationException
- Preprocess: this ensures space is available for local variables declared within
this global variable
- Overrides:
preprocess
in class StyleElement
getVariableName
public java.lang.String getVariableName()
- Get the display name of the variable.
getVariableFingerprint
public int getVariableFingerprint()
- Get the fingerprint of the variable name
prepareAttributes
public void prepareAttributes()
throws javax.xml.transform.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 StyleElement
validate
public void validate()
throws javax.xml.transform.TransformerConfigurationException
- Description copied from class:
StyleElement
- Check that the element is valid. This is called once for each element, after
the entire tree has been built. As well as validation, it can perform first-time
initialisation. The default implementation does nothing; it is normally overriden
in subclasses.
- Overrides:
validate
in class StyleElement
checkDuplicateDeclaration
public void checkDuplicateDeclaration()
throws javax.xml.transform.TransformerConfigurationException
- Check whether this declaration duplicates another one
getSelectValue
protected Value getSelectValue(Context context)
throws javax.xml.transform.TransformerException
- Get the value of the select expression if present or the content of the element otherwise
getProcedure
public Procedure getProcedure()
- Get associated Procedure (for details of stack frame, if this is a global variable containing
local variable declarations)
