setExpressions

public void setExpressions(java.util.List<DerivedColumn> expressions)

getType

public java.lang.Class<?> getType()

Description copied from interface: Expression

Get the return type of this expression. This method will not necessarily work right before resolution (Expression.isResolved() returns true).

Specified by:

getType in interface Expression

Returns:

Java class name

isResolved

public boolean isResolved()

Description copied from interface: Expression

Return true if expression has been fully resolved. Typically the QueryResolver component will handle resolution of an expression.

Specified by:

isResolved in interface Expression

Returns:

True if resolved

acceptVisitor

public void acceptVisitor(LanguageVisitor visitor)

Description copied from interface: LanguageObject

Method for accepting a visitor. It is the responsibility of the language object to call back on the visitor.

Specified by:

acceptVisitor in interface LanguageObject

Parameters:

visitor - Visitor being used

clone

public TextLine clone()

Description copied from interface: LanguageObject

Implement clone to make objects cloneable.

Specified by:

clone in interface LanguageObject

Overrides:

clone in class java.lang.Object

Returns:

Deep clone of this object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

evaluate

public static <T> java.lang.String evaluate(java.util.List<T> values,
                                            TextLine.ValueExtractor<T> valueExtractor,
                                            java.lang.Character delimeter,
                                            java.lang.Character quote)
                                 throws TransformationException

Throws:

TransformationException
