Method Detail

getTarget

public java.lang.Class<? super java.lang.Number> getTarget()

Specified by:

getTarget in interface uk.ac.ed.epcc.webapp.Targetted<java.lang.Number>

getDuration

accept

public <R> R accept(BasePropExpressionVisitor<R> vis)
         throws java.lang.Exception

Description copied from interface: PropExpression

Visitor pattern. Have the BasePropExpressionVisitor visit this expression

Specified by:

accept in interface PropExpression<java.lang.Number>

Throws:

java.lang.Exception

Type Parameters:

R - type of return

Parameters:

vis - visitor

Returns:

result of type R

copy

public PropExpression<java.lang.Number> copy()

Description copied from interface: PropExpression

Generate an equivalent (and where possible immutable) copy of this expression. Most implementing types should themselves be immutable, calling copy on their arguments and returning a self-reference for copy. In this case the return type of the function should be narrowed to the implemeting sub-type.

Specified by:

copy in interface PropExpression<java.lang.Number>

Returns:

PropExpression

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object
