Arg

• java.lang.Object

Fields Summary
private QName	m_qname Field m_qname: The name of this argument, expressed as a QName (Qualified Name) object.
private XObject	m_val Field m_val: Stored XObject value of this argument
private String	m_expression Field m_expression: Stored expression value of this argument.
private boolean	m_isFromWithParam True if this variable was added with an xsl:with-param or is added via setParameter.
private boolean	m_isVisible True if this variable is currently visible. To be visible, a variable needs to come either from xsl:variable or be a "received" parameter, ie one for which an xsl:param has been encountered. Set at the time the object is constructed and updated as needed.

Constructors Summary
public Arg() Construct a dummy parameter argument, with no QName and no value (either expression string or value XObject). isVisible defaults to true. m_qname = new QName(""); ; // so that string compares can be done. m_val = null; m_expression = null; m_isVisible = true; m_isFromWithParam = false;
public Arg(QName qname, String expression, boolean isFromWithParam) Construct a parameter argument that contains an expression. param qname Name of the argument, expressed as a QName object. param expression String to be stored as this argument's value expression. param isFromWithParam True if this is a parameter variable. m_qname = qname; m_val = null; m_expression = expression; m_isFromWithParam = isFromWithParam; m_isVisible = !isFromWithParam;
public Arg(QName qname, XObject val) Construct a parameter argument which has an XObject value. isVisible defaults to true. param qname Name of the argument, expressed as a QName object. param val Value of the argument, expressed as an XObject m_qname = qname; m_val = val; m_isVisible = true; m_isFromWithParam = false; m_expression = null;
public Arg(QName qname, XObject val, boolean isFromWithParam) Construct a parameter argument. param qname Name of the argument, expressed as a QName object. param val Value of the argument, expressed as an XObject param isFromWithParam True if this is a parameter variable. m_qname = qname; m_val = val; m_isFromWithParam = isFromWithParam; m_isVisible = !isFromWithParam; m_expression = null;

Methods Summary
public void	detach() Have the object release it's resources. Call only when the variable or argument is going out of scope. if(null != m_val) { m_val.allowDetachToRelease(true); m_val.detach(); }
public boolean	equals(java.lang.Object obj) Equality function specialized for the variable name. If the argument is not a qname, it will deligate to the super class. param obj the reference object with which to compare. return true if this object is the same as the obj argument; false otherwise. if(obj instanceof QName) { return m_qname.equals(obj); } else return super.equals(obj);
public java.lang.String	getExpression() Get the value expression for this argument. return String containing the expression previously stored into this argument see #setExpression return m_expression;
public final com.sun.org.apache.xml.internal.utils.QName	getQName() Get the qualified name for this argument. return QName object containing the qualified name return m_qname;
public final com.sun.org.apache.xpath.internal.objects.XObject	getVal() Get the value for this argument. return the argument's stored XObject value. see #setVal(XObject) return m_val;
public boolean	isFromWithParam() Tell if this variable is a parameter passed with a with-param or as a top-level parameter. return m_isFromWithParam;
public boolean	isVisible() Tell if this variable is currently visible. return m_isVisible;
public void	setExpression(java.lang.String expr) Set the value expression for this argument. param expr String containing the expression to be stored as this argument's value. see #getExpression m_expression = expr;
public void	setIsVisible(boolean b) Update visibility status of this variable. m_isVisible = b;
public final void	setQName(com.sun.org.apache.xml.internal.utils.QName name) Set the qualified name for this argument. param name QName object representing the new Qualified Name. m_qname = name;
public final void	setVal(com.sun.org.apache.xpath.internal.objects.XObject val) Set the value of this argument. param val an XObject representing the arguments's value. see #getVal() m_val = val;
