 org.apache.xpath.Arg
| Arg | | public class Arg (Code) | | This class holds an instance of an argument on
the stack. The value of the argument can be either an
XObject or a String containing an expression.
|
| Constructor Summary | |
| public | Arg()
Construct a dummy parameter argument, with no QName and no
value (either expression string or value XObject). | | public | Arg(QName qname, String expression, boolean isFromWithParam)
Construct a parameter argument that contains an expression. | | public | Arg(QName qname, XObject val)
Construct a parameter argument which has an XObject value. | | public | Arg(QName qname, XObject val, boolean isFromWithParam)
Construct a parameter argument. |
| Method Summary | |
| public void | detach()
Have the object release it's resources. | | public boolean | equals(Object obj)
Equality function specialized for the variable name. | | public String | getExpression()
Get the value expression for this argument. | | final public QName | getQName()
Get the qualified name for this argument. | | final public XObject | getVal()
Get the value for this argument. | | public boolean | isFromWithParam()
Tell if this variable is a parameter passed with a with-param or as
a top-level parameter. | | public boolean | isVisible()
Tell if this variable is currently visible. | | public void | setExpression(String expr)
Set the value expression for this argument. | | public void | setIsVisible(boolean b)
Update visibility status of this variable. | | final public void | setQName(QName name)
Set the qualified name for this argument. | | final public void | setVal(XObject val)
Set the value of this argument. |
| Arg | | public Arg()(Code) | | Construct a dummy parameter argument, with no QName and no
value (either expression string or value XObject). isVisible
defaults to true.
|
| Arg | | public Arg(QName qname, String expression, boolean isFromWithParam)(Code) | | Construct a parameter argument that contains an expression.
Parameters:
qname - Name of the argument, expressed as a QName object.
Parameters:
expression - String to be stored as this argument's value expression.
Parameters:
isFromWithParam - True if this is a parameter variable. |
| Arg | | public Arg(QName qname, XObject val)(Code) | | Construct a parameter argument which has an XObject value.
isVisible defaults to true.
Parameters:
qname - Name of the argument, expressed as a QName object.
Parameters:
val - Value of the argument, expressed as an XObject |
| Arg | | public Arg(QName qname, XObject val, boolean isFromWithParam)(Code) | | Construct a parameter argument.
Parameters:
qname - Name of the argument, expressed as a QName object.
Parameters:
val - Value of the argument, expressed as an XObject
Parameters:
isFromWithParam - True if this is a parameter variable. |
| detach | | public void detach()(Code) | | Have the object release it's resources.
Call only when the variable or argument is going out of scope.
|
| equals | | public boolean equals(Object obj)(Code) | | Equality function specialized for the variable name. If the argument
is not a qname, it will deligate to the super class.
Parameters:
obj - the reference object with which to compare. true if this object is the same as the objargument; false otherwise. |
| getExpression | | public String getExpression()(Code) | | Get the value expression for this argument.
String containing the expression previously stored into thisargument

| getQName | | final public QName getQName()(Code) | | Get the qualified name for this argument.
QName object containing the qualified name |
| isFromWithParam | | public boolean isFromWithParam()(Code) | | Tell if this variable is a parameter passed with a with-param or as
a top-level parameter.
|
| isVisible | | public boolean isVisible()(Code) | | Tell if this variable is currently visible.
|
| setExpression | | public void setExpression(String expr)(Code) | | Set the value expression for this argument.
Parameters:
expr - String containing the expression to be stored as thisargument's value.
See Also: Arg.getExpression |
| setIsVisible | | public void setIsVisible(boolean b)(Code) | | Update visibility status of this variable.
|
| setQName | | final public void setQName(QName name)(Code) | | Set the qualified name for this argument.
Parameters:
name - QName object representing the new Qualified Name. |
| setVal | | final public void setVal(XObject val)(Code) | | Set the value of this argument.
Parameters:
val - an XObject representing the arguments's value.
