Constructor Detail

FloatLiteralExpr

public FloatLiteralExpr()
The noarg constructor is needed for ANTLR support and deserialization. The caller must make sure to set the ANTLR tree structure himself or, call setChildren optionally.


FloatLiteralExpr

public FloatLiteralExpr(antlr.Token token)
The noarg constructor is needed for ANTLR support. The caller must make sure to set the ANTLR tree structure himself or, call setChildren optionally.


FloatLiteralExpr

FloatLiteralExpr(java.lang.Float f)
This constructor is called by the query tree instance. It delegates to the super class constructor.

Parameters:
f - the float value

FloatLiteralExpr

FloatLiteralExpr(float f)
This constructor is called by the query tree instance. It delegates to the super class constructor.

Parameters:
f - the float value
Method Detail

getFloat

public float getFloat()
Returns the float value represented by this expression.

Specified by:
getFloat in interface FloatLiteralExpression
Returns:
the float value

arrive

public void arrive(NodeVisitor visitor)
Delegates to the argument visitor.

Specified by:
arrive in interface Node
Overrides:
arrive in class ConstantExpr
Parameters:
visitor - the node visitor

leave

public java.lang.Object leave(NodeVisitor visitor,
                              java.lang.Object[] results)
Delegates to the argument visitor.

Specified by:
leave in interface Node
Overrides:
leave in class ConstantExpr
Parameters:
visitor - the node visitor
results - the result array
Returns:
the object returned by the visitor instance
